-What:		/sys/kernel/debug/kmemtrace/
-Date:		July 2008
-Contact:	Eduard - Gabriel Munteanu <eduard.munteanu@linux360.ro>
-Description:
-
-In kmemtrace-enabled kernels, the following files are created:
-
-/sys/kernel/debug/kmemtrace/
-	cpu<n>		(0400)	Per-CPU tracing data, see below. (binary)
-	total_overruns	(0400)	Total number of bytes which were dropped from
-				cpu<n> files because of full buffer condition,
-				non-binary. (text)
-	abi_version	(0400)	Kernel's kmemtrace ABI version. (text)
-
-Each per-CPU file should be read according to the relay interface. That is,
-the reader should set affinity to that specific CPU and, as currently done by
-the userspace application (though there are other methods), use poll() with
-an infinite timeout before every read(). Otherwise, erroneous data may be
-read. The binary data has the following _core_ format:
-
-	Event ID	(1 byte)	Unsigned integer, one of:
-		0 - represents an allocation (KMEMTRACE_EVENT_ALLOC)
-		1 - represents a freeing of previously allocated memory
-		    (KMEMTRACE_EVENT_FREE)
-	Type ID		(1 byte)	Unsigned integer, one of:
-		0 - this is a kmalloc() / kfree()
-		1 - this is a kmem_cache_alloc() / kmem_cache_free()
-		2 - this is a __get_free_pages() et al.
-	Event size	(2 bytes)	Unsigned integer representing the
-					size of this event. Used to extend
-					kmemtrace. Discard the bytes you
-					don't know about.
-	Sequence number	(4 bytes)	Signed integer used to reorder data
-					logged on SMP machines. Wraparound
-					must be taken into account, although
-					it is unlikely.
-	Caller address	(8 bytes)	Return address to the caller.
-	Pointer to mem	(8 bytes)	Pointer to target memory area. Can be
-					NULL, but not all such calls might be
-					recorded.
-
-In case of KMEMTRACE_EVENT_ALLOC events, the next fields follow:
-
-	Requested bytes	(8 bytes)	Total number of requested bytes,
-					unsigned, must not be zero.
-	Allocated bytes (8 bytes)	Total number of actually allocated
-					bytes, unsigned, must not be lower
-					than requested bytes.
-	Requested flags	(4 bytes)	GFP flags supplied by the caller.
-	Target CPU	(4 bytes)	Signed integer, valid for event id 1.
-					If equal to -1, target CPU is the same
-					as origin CPU, but the reverse might
-					not be true.
-
-The data is made available in the same endianness the machine has.
-
-Other event ids and type ids may be defined and added. Other fields may be
-added by increasing event size, but see below for details.
-Every modification to the ABI, including new id definitions, are followed
-by bumping the ABI version by one.
-
-Adding new data to the packet (features) is done at the end of the mandatory
-data:
-	Feature size	(2 byte)
-	Feature ID	(1 byte)
-	Feature data	(Feature size - 3 bytes)
-
-
-Users:
-	kmemtrace-user - git://repo.or.cz/kmemtrace-user.git

+Description:
+		The /sys/power/wakeup_count file allows user space to put the
+		system into a sleep state while taking into account the
+		concurrent arrival of wakeup events.  Reading from it returns
+		the current number of registered wakeup events and it blocks if
+		some wakeup events are being processed at the time the file is
+		read from.  Writing to it will only succeed if the current
+		number of wakeup events is equal to the written value and, if
+		successful, will make the kernel abort a subsequent transition
+		to a sleep state if any wakeup events are reported after the
+		write has returned.

+<title>Introduction</title>
+
+<para>The LIRC device interface is a bi-directional interface for
+transporting raw IR data between userspace and kernelspace. Fundamentally,
+it is just a chardev (/dev/lircX, for X = 0, 1, 2, ...), with a number
+of standard struct file_operations defined on it. With respect to
+transporting raw IR data to and fro, the essential fops are read, write
+and ioctl.</para>
+
+<para>Example dmesg output upon a driver registering w/LIRC:</para>
+  <blockquote>
+    <para>$ dmesg |grep lirc_dev</para>
+    <para>lirc_dev: IR Remote Control driver registered, major 248</para>
+    <para>rc rc0: lirc_dev: driver ir-lirc-codec (mceusb) registered at minor = 0</para>
+  </blockquote>
+
+<para>What you should see for a chardev:</para>
+  <blockquote>
+    <para>$ ls -l /dev/lirc*</para>

+</section>
+
+<section id="lirc_read">
+<title>LIRC read fop</title>
+
+<para>The lircd userspace daemon reads raw IR data from the LIRC chardev. The
+exact format of the data depends on what modes a driver supports, and what
+mode has been selected. lircd obtains supported modes and sets the active mode
+via the ioctl interface, detailed at <xref linkend="lirc_ioctl"/>. The generally
+preferred mode is LIRC_MODE_MODE2, in which packets containing an int value
+describing an IR signal are read from the chardev.</para>
+
+<para>See also <ulink url="http://www.lirc.org/html/technical.html">http://www.lirc.org/html/technical.html</ulink> for more info.</para>
+</section>
+
+<section id="lirc_write">
+<title>LIRC write fop</title>
+
+<para>The data written to the chardev is a pulse/space sequence of integer
+values. Pulses and spaces are only marked implicitly by their position. The
+data must start and end with a pulse, therefore, the data must always include
+an unevent number of samples. The write function must block until the data has
+been transmitted by the hardware.</para>
+</section>
+
+<section id="lirc_ioctl">
+<title>LIRC ioctl fop</title>
+
+<para>The LIRC device's ioctl definition is bound by the ioctl function
+definition of struct file_operations, leaving us with an unsigned int
+for the ioctl command and an unsigned long for the arg. For the purposes
+of ioctl portability across 32-bit and 64-bit, these values are capped
+to their 32-bit sizes.</para>
+
+<para>The following ioctls can be used to change specific hardware settings.
+In general each driver should have a default set of settings. The driver
+implementation is expected to re-apply the default settings when the device
+is closed by user-space, so that every application opening the device can rely
+on working with the default settings initially.</para>

+Yama is a Linux Security Module that collects a number of security
+protections that are not handled by the core kernel itself.  To select
+it at boot time, specify "security=yama" (though this will disable any
+other LSM).
+
+Yama is controlled through sysctl in /proc/sys/kernel/yama:
+
+- protected_sticky_symlinks
+- protected_nonaccess_hardlinks
+- ptrace_scope
+
+==============================================================
+
+protected_sticky_symlinks:
+
+A long-standing class of security issues is the symlink-based
+time-of-check-time-of-use race, most commonly seen in world-writable
+directories like /tmp. The common method of exploitation of this flaw
+is to cross privilege boundaries when following a given symlink (i.e. a
+root process follows a symlink belonging to another user).  For a likely
+incomplete list of hundreds of examples across the years, please see:
+http://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=/tmp
+
+When set to "0", symlink following behavior is unrestricted.
+
+When set to "1" symlinks are permitted to be followed only when outside
+a sticky world-writable directory, or when the uid of the symlink and
+follower match, or when the directory owner matches the symlink's owner.
+
+This protection is based on the restrictions in Openwall and grsecurity.
+
+==============================================================
+
+protected_nonaccess_hardlinks:
+
+Hardlinks can be abused in a similar fashion to symlinks in sticky
+world-writable directories, but their weakness is not limited to
+just that scenario. For example, if /etc and /home are on the same
+partition, a regular user can create a hardlink to /etc/shadow in their
+home directory. While it retains the original owner and permissions,
+it is possible for privileged programs that are otherwise symlink-safe
+to mistakenly access the file through its hardlink. Additionally, a very
+minor untraceable quota-bypassing local denial of service is possible by
+an attacker exhausting disk space by filling a world-writable directory
+with hardlinks.
+
+When set to "0", hardlink creation behavior is unrestricted.
+
+When set to "1", hardlinks cannot be created to files that a given user
+would be unable to read and write originally, or are otherwise sensitive.
+
+This protection is based on the restrictions in Openwall and grsecurity.
+
+==============================================================
+
+ptrace_scope:
+
+As Linux grows in popularity, it will become a larger target for
+malware. One particularly troubling weakness of the Linux process
+interfaces is that a single user is able to examine the memory and
+running state of any of their processes. For example, if one application
+(e.g. Pidgin) was compromised, it would be possible for an attacker to
+attach to other running processes (e.g. Firefox, SSH sessions, GPG agent,
+etc) to extract additional credentials and continue to expand the scope
+of their attack without resorting to user-assisted phishing.
+
+This is not a theoretical problem. SSH session hijacking
+(http://www.storm.net.nz/projects/7) and arbitrary code injection
+(http://c-skills.blogspot.com/2007/05/injectso.html) attacks already
+exist and remain possible if PTRACE is allowed to operate as before.
+PTRACE is not commonly used by non-developers and non-admins, so system
+builders should be allowed the option to disable this debugging system.
+
+For a solution, some applications use prctl(PR_SET_DUMPABLE, ...) to
+specifically disallow such PTRACE attachment (e.g. ssh-agent), but many
+do not. A more general solution is to only allow PTRACE directly from a
+parent to a child process (i.e. direct "gdb EXE" and "strace EXE" still
+work), or with CAP_SYS_PTRACE (i.e. "gdb --pid=PID", and "strace -p PID"
+still work as root).
+
+0 - classic PTRACE permissions: a process can PTRACE any other process
+    running under the same uid, as long as it is dumpable (i.e. did not
+    transition uids, start privileged, or have prctl(PR_SET_DUMPABLE...)
+    called).
+
+1 - child-only PTRACE: a process can PTRACE only its descendants when
+    the above classic criteria is also met.
+
+This protection is based on the restrictions in grsecurity.

+
+ Getting Coccinelle
+~~~~~~~~~~~~~~~~~~~~
+
+The semantic patches included in the kernel use the 'virtual rule'
+feature which was introduced in Coccinelle version 0.1.11.
+
+Coccinelle (>=0.2.0) is available through the package manager
+of many distributions, e.g. :
+
+ - Debian (>=squeeze)
+ - Fedora (>=13)
+ - Ubuntu (>=10.04 Lucid Lynx)
+ - OpenSUSE
+ - Arch Linux
+ - NetBSD
+ - FreeBSD
+
+
+You can get the latest version released from the Coccinelle homepage at
+http://coccinelle.lip6.fr/
+
+Once you have it, run the following command:
+
+     	./configure
+        make
+
+as a regular user, and install it with
+
+        sudo make install
+
+
+ Using Coccinelle on the Linux kernel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A Coccinelle-specific target is defined in the top level
+Makefile. This target is named 'coccicheck' and calls the 'coccicheck'
+front-end in the 'scripts' directory.
+
+Four modes are defined: report, patch, context, and org. The mode to
+use is specified by setting the MODE variable with 'MODE=<mode>'.
+
+'report' generates a list in the following format:
+  file:line:column-column: message
+
+'patch' proposes a fix, when possible.
+
+'context' highlights lines of interest and their context in a
+diff-like style.Lines of interest are indicated with '-'.
+
+'org' generates a report in the Org mode format of Emacs.
+
+Note that not all semantic patches implement all modes.
+
+To make a report for every semantic patch, run the following command:
+
+	make coccicheck MODE=report
+
+NB: The 'report' mode is the default one.
+
+To produce patches, run:
+
+	make coccicheck MODE=patch
+
+
+The coccicheck target applies every semantic patch available in the
+subdirectories of 'scripts/coccinelle' to the entire Linux kernel.
+
+For each semantic patch, a changelog message is proposed.  It gives a
+description of the problem being checked by the semantic patch, and
+includes a reference to Coccinelle.
+
+As any static code analyzer, Coccinelle produces false
+positives. Thus, reports must be carefully checked, and patches
+reviewed.
+
+
+ Using Coccinelle with a single semantic patch
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The optional make variable COCCI can be used to check a single
+semantic patch. In that case, the variable must be initialized with
+the name of the semantic patch to apply.
+
+For instance:
+
+	make coccicheck COCCI=<my_SP.cocci> MODE=patch
+or
+	make coccicheck COCCI=<my_SP.cocci> MODE=report
+
+
+ Proposing new semantic patches
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New semantic patches can be proposed and submitted by kernel
+developers. For sake of clarity, they should be organized in the
+subdirectories of 'scripts/coccinelle/'.
+
+
+ Detailed description of the 'report' mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+'report' generates a list in the following format:
+  file:line:column-column: message
+
+Example:
+
+Running
+
+	make coccicheck MODE=report COCCI=scripts/coccinelle/err_cast.cocci
+
+will execute the following part of the SmPL script.
+
+<smpl>

+

+illustrated below:

+/home/user/linux/crypto/xts.c:227:9-16: ERR_CAST can be used with alg
+
+
+ Detailed description of the 'patch' mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When the 'patch' mode is available, it proposes a fix for each problem
+identified.
+
+Example:
+
+Running
+	make coccicheck MODE=patch COCCI=scripts/coccinelle/err_cast.cocci
+

+
+Description
+-----------
+
+The Standard Microsystems Corporation (SMSC) EMC2103 chips
+contain up to 4 temperature sensors and a single fan controller.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 1, the lowest
+representable value is 480 RPM.
+
+This driver supports RPM based control, to use this a fan target
+should be written to fan1_target and pwm1_enable should be set to 3.
+
+The 2103-2 and 2103-4 variants have a third temperature sensor, which can
+be connected to two anti-parallel diodes.  These values can be read
+as temp3 and temp4.  If only one diode is attached to this channel, temp4
+will show as "fault".  The module parameter "apd=0" can be used to suppress
+this 4th channel when anti-parallel diodes are not fitted.

+If you have NOT configured the driver to sample all GPIO pins as analog
+voltages, then the in10_input and in11_input sysfs attributes will not be
+created. The driver will sample the GPIO pin that is currently connected to the
+ADC as an analog voltage, and report the value in in9_input.
+
+If you have configured the driver to sample all GPIO pins as analog voltages,
+then they will be sampled in round-robin fashion. If userspace reads too
+slowly, -EAGAIN will be returned when you read the sysfs attribute containing
+the sensor reading.
+
+The LTC4245 chip can be configured to sample all GPIO pins with two methods:
+1) platform data -- see include/linux/i2c/ltc4245.h
+2) OF device tree -- add the "ltc4245,use-extra-gpios" property to each chip
+
+The default mode of operation is to sample a single GPIO pin.

+
+Capability: KVM_CAP_SET_IDENTITY_MAP_ADDR
+Architectures: x86
+Type: vm ioctl
+Parameters: unsigned long identity (in)
+Returns: 0 on success, -1 on error
+
+This ioctl defines the physical address of a one-page region in the guest

+guest physical address space and must not conflict with any memory slot
+or any mmio address.  The guest may malfunction if it accesses this memory

+Emulating cr0.wp
+================
+
+If tdp is not enabled, the host must keep cr0.wp=1 so page write protection
+works for the guest kernel, not guest guest userspace.  When the guest
+cr0.wp=1, this does not present a problem.  However when the guest cr0.wp=0,
+we cannot map the permissions for gpte.u=1, gpte.w=0 to any spte (the
+semantics require allowing any guest kernel access plus user read access).
+
+We handle this by mapping the permissions to two possible sptes, depending
+on fault type:
+
+- kernel write fault: spte.u=0, spte.w=1 (allows full kernel access,
+  disallows user access)
+- read fault: spte.u=1, spte.w=0 (allows full read access, disallows kernel
+  write access)
+
+(user write faults generate a #PF)
+
+Large pages
+===========
+
+The mmu supports all combinations of large and small guest and host pages.
+Supported page sizes include 4k, 2M, 4M, and 1G.  4M pages are treated as
+two separate 2M pages, on both guest and host, since the mmu always uses PAE
+paging.
+
+To instantiate a large spte, four constraints must be satisfied:
+
+- the spte must point to a large host page
+- the guest pte must be a large pte of at least equivalent size (if tdp is
+  enabled, there is no guest pte and this condition is satisified)
+- if the spte will be writeable, the large page frame may not overlap any
+  write-protected pages
+- the guest page must be wholly contained by a single memory slot
+
+To check the last two conditions, the mmu maintains a ->write_count set of
+arrays for each memory slot and large page size.  Every write protected page
+causes its write_count to be incremented, thus preventing instantiation of
+a large spte.  The frames at the end of an unaligned memory slot have
+artificically inflated ->write_counts so they can never be instantiated.

+KVM-specific MSRs.
+Glauber Costa <glommer@redhat.com>, Red Hat Inc, 2010
+=====================================================
+
+KVM makes use of some custom MSRs to service some requests.
+At present, this facility is only used by kvmclock.
+
+Custom MSRs have a range reserved for them, that goes from
+0x4b564d00 to 0x4b564dff. There are MSRs outside this area,
+but they are deprecated and their use is discouraged.
+
+Custom MSR list
+--------
+
+The current supported Custom MSR list is:
+
+MSR_KVM_WALL_CLOCK_NEW:   0x4b564d00
+
+	data: 4-byte alignment physical address of a memory area which must be
+	in guest RAM. This memory is expected to hold a copy of the following
+	structure:
+
+	struct pvclock_wall_clock {
+		u32   version;
+		u32   sec;
+		u32   nsec;
+	} __attribute__((__packed__));
+
+	whose data will be filled in by the hypervisor. The hypervisor is only
+	guaranteed to update this data at the moment of MSR write.
+	Users that want to reliably query this information more than once have
+	to write more than once to this MSR. Fields have the following meanings:
+
+		version: guest has to check version before and after grabbing
+		time information and check that they are both equal and even.
+		An odd version indicates an in-progress update.
+
+		sec: number of seconds for wallclock.
+
+		nsec: number of nanoseconds for wallclock.
+
+	Note that although MSRs are per-CPU entities, the effect of this
+	particular MSR is global.
+
+	Availability of this MSR must be checked via bit 3 in 0x4000001 cpuid
+	leaf prior to usage.
+
+MSR_KVM_SYSTEM_TIME_NEW:  0x4b564d01
+
+	data: 4-byte aligned physical address of a memory area which must be in
+	guest RAM, plus an enable bit in bit 0. This memory is expected to hold
+	a copy of the following structure:
+
+	struct pvclock_vcpu_time_info {
+		u32   version;
+		u32   pad0;
+		u64   tsc_timestamp;
+		u64   system_time;
+		u32   tsc_to_system_mul;
+		s8    tsc_shift;
+		u8    flags;
+		u8    pad[2];
+	} __attribute__((__packed__)); /* 32 bytes */
+
+	whose data will be filled in by the hypervisor periodically. Only one
+	write, or registration, is needed for each VCPU. The interval between
+	updates of this structure is arbitrary and implementation-dependent.
+	The hypervisor may update this structure at any time it sees fit until
+	anything with bit0 == 0 is written to it.
+
+	Fields have the following meanings:
+
+		version: guest has to check version before and after grabbing
+		time information and check that they are both equal and even.
+		An odd version indicates an in-progress update.
+
+		tsc_timestamp: the tsc value at the current VCPU at the time
+		of the update of this structure. Guests can subtract this value
+		from current tsc to derive a notion of elapsed time since the
+		structure update.
+
+		system_time: a host notion of monotonic time, including sleep
+		time at the time this structure was last updated. Unit is
+		nanoseconds.
+
+		tsc_to_system_mul: a function of the tsc frequency. One has
+		to multiply any tsc-related quantity by this value to get
+		a value in nanoseconds, besides dividing by 2^tsc_shift
+
+		tsc_shift: cycle to nanosecond divider, as a power of two, to
+		allow for shift rights. One has to shift right any tsc-related
+		quantity by this value to get a value in nanoseconds, besides
+		multiplying by tsc_to_system_mul.
+
+		With this information, guests can derive per-CPU time by
+		doing:
+
+			time = (current_tsc - tsc_timestamp)
+			time = (time * tsc_to_system_mul) >> tsc_shift
+			time = time + system_time
+
+		flags: bits in this field indicate extended capabilities
+		coordinated between the guest and the hypervisor. Availability
+		of specific flags has to be checked in 0x40000001 cpuid leaf.
+		Current flags are:
+
+		 flag bit   | cpuid bit    | meaning
+		-------------------------------------------------------------
+			    |	           | time measures taken across
+		     0      |	   24      | multiple cpus are guaranteed to
+			    |		   | be monotonic
+		-------------------------------------------------------------
+
+	Availability of this MSR must be checked via bit 3 in 0x4000001 cpuid
+	leaf prior to usage.
+
+
+MSR_KVM_WALL_CLOCK:  0x11
+
+	data and functioning: same as MSR_KVM_WALL_CLOCK_NEW. Use that instead.
+
+	This MSR falls outside the reserved KVM range and may be removed in the
+	future. Its usage is deprecated.
+
+	Availability of this MSR must be checked via bit 0 in 0x4000001 cpuid
+	leaf prior to usage.
+
+MSR_KVM_SYSTEM_TIME: 0x12
+
+	data and functioning: same as MSR_KVM_SYSTEM_TIME_NEW. Use that instead.

+	This MSR falls outside the reserved KVM range and may be removed in the
+	future. Its usage is deprecated.
+
+	Availability of this MSR must be checked via bit 0 in 0x4000001 cpuid
+	leaf prior to usage.
+
+	The suggested algorithm for detecting kvmclock presence is then:
+
+		if (!kvm_para_available())    /* refer to cpuid.txt */
+			return NON_PRESENT;

+		if (flags & 3) {
+			msr_kvm_system_time = MSR_KVM_SYSTEM_TIME_NEW;
+			msr_kvm_wall_clock = MSR_KVM_WALL_CLOCK_NEW;
+			return PRESENT;
+		} else if (flags & 0) {

+			msr_kvm_wall_clock = MSR_KVM_WALL_CLOCK;
+			return PRESENT;

-4. Querying Bonding Configuration 
+3.5 Overriding Configuration for Special Cases
+----------------------------------------------
+When using the bonding driver, the physical port which transmits a frame is
+typically selected by the bonding driver, and is not relevant to the user or
+system administrator.  The output port is simply selected using the policies of
+the selected bonding mode.  On occasion however, it is helpful to direct certain
+classes of traffic to certain physical interfaces on output to implement
+slightly more complex policies.  For example, to reach a web server over a
+bonded interface in which eth0 connects to a private network, while eth1
+connects via a public network, it may be desirous to bias the bond to send said
+traffic over eth0 first, using eth1 only as a fall back, while all other traffic
+can safely be sent over either interface.  Such configurations may be achieved
+using the traffic control utilities inherent in linux.
+
+By default the bonding driver is multiqueue aware and 16 queues are created
+when the driver initializes (see Documentation/networking/multiqueue.txt
+for details).  If more or less queues are desired the module parameter
+tx_queues can be used to change this value.  There is no sysfs parameter
+available as the allocation is done at module init time.
+
+The output of the file /proc/net/bonding/bondX has changed so the output Queue
+ID is now printed for each slave:
+
+Bonding Mode: fault-tolerance (active-backup)
+Primary Slave: None
+Currently Active Slave: eth0
+MII Status: up
+MII Polling Interval (ms): 0
+Up Delay (ms): 0
+Down Delay (ms): 0
+
+Slave Interface: eth0
+MII Status: up
+Link Failure Count: 0
+Permanent HW addr: 00:1a:a0:12:8f:cb
+Slave queue ID: 0
+
+Slave Interface: eth1
+MII Status: up
+Link Failure Count: 0
+Permanent HW addr: 00:1a:a0:12:8f:cc
+Slave queue ID: 2
+
+The queue_id for a slave can be set using the command:
+
+# echo "eth1:2" > /sys/class/net/bond0/bonding/queue_id
+
+Any interface that needs a queue_id set should set it with multiple calls
+like the one above until proper priorities are set for all interfaces.  On
+distributions that allow configuration via initscripts, multiple 'queue_id'
+arguments can be added to BONDING_OPTS to set all needed slave queues.
+
+These queue id's can be used in conjunction with the tc utility to configure
+a multiqueue qdisc and filters to bias certain traffic to transmit on certain
+slave devices.  For instance, say we wanted, in the above configuration to
+force all traffic bound to 192.168.1.100 to use eth1 in the bond as its output
+device. The following commands would accomplish this:
+
+# tc qdisc add dev bond0 handle 1 root multiq
+
+# tc filter add dev bond0 protocol ip parent 1: prio 1 u32 match ip dst \
+	192.168.1.100 action skbedit queue_mapping 2
+
+These commands tell the kernel to attach a multiqueue queue discipline to the
+bond0 interface and filter traffic enqueued to it, such that packets with a dst
+ip of 192.168.1.100 have their output queue mapping value overwritten to 2.
+This value is then passed into the driver, causing the normal output path
+selection policy to be overridden, selecting instead qid 2, which maps to eth1.
+
+Note that qid values begin at 1.  Qid 0 is reserved to initiate to the driver
+that normal output policy selection should take place.  One benefit to simply
+leaving the qid for a slave to 0 is the multiqueue awareness in the bonding
+driver that is now present.  This awareness allows tc filters to be placed on
+slave devices as well as bond devices and the bonding driver will simply act as
+a pass-through for selecting output queues on the slave device rather than 
+output port selection.
+
+This feature first appeared in bonding driver version 3.7.0 and support for
+output slave selection was limited to round-robin and active-backup modes.

+- CAIF SPI porting -
+
+- CAIF SPI basics:
+
+Running CAIF over SPI needs some extra setup, owing to the nature of SPI.
+Two extra GPIOs have been added in order to negotiate the transfers
+ between the master and the slave. The minimum requirement for running
+CAIF over SPI is a SPI slave chip and two GPIOs (more details below).
+Please note that running as a slave implies that you need to keep up
+with the master clock. An overrun or underrun event is fatal.
+
+- CAIF SPI framework:
+
+To make porting as easy as possible, the CAIF SPI has been divided in
+two parts. The first part (called the interface part) deals with all
+generic functionality such as length framing, SPI frame negotiation
+and SPI frame delivery and transmission. The other part is the CAIF
+SPI slave device part, which is the module that you have to write if
+you want to run SPI CAIF on a new hardware. This part takes care of
+the physical hardware, both with regard to SPI and to GPIOs.
+
+- Implementing a CAIF SPI device:
+
+	- Functionality provided by the CAIF SPI slave device:
+
+	In order to implement a SPI device you will, as a minimum,
+	need to implement the following
+	functions:
+
+	int (*init_xfer) (struct cfspi_xfer * xfer, struct cfspi_dev *dev):
+
+	This function is called by the CAIF SPI interface to give
+	you a chance to set up your hardware to be ready to receive
+	a stream of data from the master. The xfer structure contains
+	both physical and logical adresses, as well as the total length
+	of the transfer in both directions.The dev parameter can be used
+	to map to different CAIF SPI slave devices.
+
+	void (*sig_xfer) (bool xfer, struct cfspi_dev *dev):
+
+	This function is called by the CAIF SPI interface when the output
+	(SPI_INT) GPIO needs to change state. The boolean value of the xfer
+	variable indicates whether the GPIO should be asserted (HIGH) or
+	deasserted (LOW). The dev parameter can be used to map to different CAIF
+	SPI slave devices.
+
+	- Functionality provided by the CAIF SPI interface:
+
+	void (*ss_cb) (bool assert, struct cfspi_ifc *ifc);
+
+	This function is called by the CAIF SPI slave device in order to
+	signal a change of state of the input GPIO (SS) to the interface.
+	Only active edges are mandatory to be reported.
+	This function can be called from IRQ context (recommended in order
+	not to introduce latency). The ifc parameter should be the pointer
+	returned from the platform probe function in the SPI device structure.
+
+	void (*xfer_done_cb) (struct cfspi_ifc *ifc);
+
+	This function is called by the CAIF SPI slave device in order to
+	report that a transfer is completed. This function should only be
+	called once both the transmission and the reception are completed.
+	This function can be called from IRQ context (recommended in order
+	not to introduce latency). The ifc parameter should be the pointer
+	returned from the platform probe function in the SPI device structure.
+
+	- Connecting the bits and pieces:
+
+		- Filling in the SPI slave device structure:
+
+		Connect the necessary callback functions.
+		Indicate clock speed (used to calculate toggle delays).
+		Chose a suitable name (helps debugging if you use several CAIF
+		SPI slave devices).
+		Assign your private data (can be used to map to your structure).
+
+		- Filling in the SPI slave platform device structure:
+		Add name of driver to connect to ("cfspi_sspi").
+		Assign the SPI slave device structure as platform data.
+
+- Padding:
+
+In order to optimize throughput, a number of SPI padding options are provided.
+Padding can be enabled independently for uplink and downlink transfers.
+Padding can be enabled for the head, the tail and for the total frame size.
+The padding needs to be correctly configured on both sides of the link.
+The padding can be changed via module parameters in cfspi_sspi.c or via
+the sysfs directory of the cfspi_sspi driver (before device registration).

++ PACKET_TIMESTAMP
+-------------------------------------------------------------------------------
+
+The PACKET_TIMESTAMP setting determines the source of the timestamp in
+the packet meta information.  If your NIC is capable of timestamping
+packets in hardware, you can request those hardware timestamps to used.
+Note: you may need to enable the generation of hardware timestamps with
+SIOCSHWTSTAMP.
+
+PACKET_TIMESTAMP accepts the same integer bit field as
+SO_TIMESTAMPING.  However, only the SOF_TIMESTAMPING_SYS_HARDWARE
+and SOF_TIMESTAMPING_RAW_HARDWARE values are recognized by
+PACKET_TIMESTAMP.  SOF_TIMESTAMPING_SYS_HARDWARE takes precedence over
+SOF_TIMESTAMPING_RAW_HARDWARE if both bits are set.
+
+    int req = 0;
+    req |= SOF_TIMESTAMPING_SYS_HARDWARE;
+    setsockopt(fd, SOL_PACKET, PACKET_TIMESTAMP, (void *) &req, sizeof(req))
+
+If PACKET_TIMESTAMP is not set, a software timestamp generated inside
+the networking stack is used (the behavior before this setting was added).
+
+See include/linux/net_tstamp.h and Documentation/networking/timestamping
+for more information on hardware timestamps.

+HPSA - Hewlett Packard Smart Array driver
+-----------------------------------------
+
+This file describes the hpsa SCSI driver for HP Smart Array controllers.
+The hpsa driver is intended to supplant the cciss driver for newer
+Smart Array controllers.  The hpsa driver is a SCSI driver, while the
+cciss driver is a "block" driver.  Actually cciss is both a block
+driver (for logical drives) AND a SCSI driver (for tape drives). This
+"split-brained" design of the cciss driver is a source of excess
+complexity and eliminating that complexity is one of the reasons
+for hpsa to exist.
+
+Supported devices:
+------------------
+
+Smart Array P212
+Smart Array P410
+Smart Array P410i
+Smart Array P411
+Smart Array P812
+Smart Array P712m
+Smart Array P711m
+StorageWorks P1210m
+
+Additionally, older Smart Arrays may work with the hpsa driver if the kernel
+boot parameter "hpsa_allow_any=1" is specified, however these are not tested
+nor supported by HP with this driver.  For older Smart Arrays, the cciss
+driver should still be used.
+
+HPSA specific entries in /sys
+-----------------------------
+
+  In addition to the generic SCSI attributes available in /sys, hpsa supports
+  the following attributes:
+
+  HPSA specific host attributes:
+  ------------------------------
+
+  /sys/class/scsi_host/host*/rescan
+  /sys/class/scsi_host/host*/firmware_revision
+
+  the host "rescan" attribute is a write only attribute.  Writing to this
+  attribute will cause the driver to scan for new, changed, or removed devices
+  (e.g. hot-plugged tape drives, or newly configured or deleted logical drives,
+  etc.) and notify the SCSI midlayer of any changes detected.  Normally this is
+  triggered automatically by HP's Array Configuration Utility (either the GUI or
+  command line variety) so for logical drive changes, the user should not
+  normally have to use this.  It may be useful when hot plugging devices like
+  tape drives, or entire storage boxes containing pre-configured logical drives.
+
+  The "firmware_revision" attribute contains the firmware version of the Smart Array.
+  For example:
+
+	root@host:/sys/class/scsi_host/host4# cat firmware_revision
+	7.14
+
+  HPSA specific disk attributes:
+  ------------------------------
+
+  /sys/class/scsi_disk/c:b:t:l/device/unique_id
+  /sys/class/scsi_disk/c:b:t:l/device/raid_level
+  /sys/class/scsi_disk/c:b:t:l/device/lunid
+
+  (where c:b:t:l are the controller, bus, target and lun of the device)
+
+  For example:
+
+	root@host:/sys/class/scsi_disk/4:0:0:0/device# cat unique_id
+	600508B1001044395355323037570F77
+	root@host:/sys/class/scsi_disk/4:0:0:0/device# cat lunid
+	0x0000004000000000
+	root@host:/sys/class/scsi_disk/4:0:0:0/device# cat raid_level
+	RAID 0
+
+HPSA specific ioctls:
+---------------------
+
+  For compatibility with applications written for the cciss driver, many, but
+  not all of the ioctls supported by the cciss driver are also supported by the
+  hpsa driver.  The data structures used by these are described in
+  include/linux/cciss_ioctl.h
+
+  CCISS_DEREGDISK
+  CCISS_REGNEWDISK
+  CCISS_REGNEWD
+
+  The above three ioctls all do exactly the same thing, which is to cause the driver
+  to rescan for new devices.  This does exactly the same thing as writing to the
+  hpsa specific host "rescan" attribute.
+
+  CCISS_GETPCIINFO
+
+	Returns PCI domain, bus, device and function and "board ID" (PCI subsystem ID).
+
+  CCISS_GETDRIVVER
+
+	Returns driver version in three bytes encoded as:
+		(major_version << 16) | (minor_version << 8) | (subminor_version)
+
+  CCISS_PASSTHRU
+  CCISS_BIG_PASSTHRU
+
+	Allows "BMIC" and "CISS" commands to be passed through to the Smart Array.
+	These are used extensively by the HP Array Configuration Utility, SNMP storage
+	agents, etc.  See cciss_vol_status at http://cciss.sf.net for some examples.

-			kmemtrace - Kernel Memory Tracer
-
-			  by Eduard - Gabriel Munteanu
-			     <eduard.munteanu@linux360.ro>
-
-I. Introduction
-===============
-
-kmemtrace helps kernel developers figure out two things:
-1) how different allocators (SLAB, SLUB etc.) perform
-2) how kernel code allocates memory and how much
-
-To do this, we trace every allocation and export information to the userspace
-through the relay interface. We export things such as the number of requested
-bytes, the number of bytes actually allocated (i.e. including internal
-fragmentation), whether this is a slab allocation or a plain kmalloc() and so
-on.
-
-The actual analysis is performed by a userspace tool (see section III for
-details on where to get it from). It logs the data exported by the kernel,
-processes it and (as of writing this) can provide the following information:
-- the total amount of memory allocated and fragmentation per call-site
-- the amount of memory allocated and fragmentation per allocation
-- total memory allocated and fragmentation in the collected dataset
-- number of cross-CPU allocation and frees (makes sense in NUMA environments)
-
-Moreover, it can potentially find inconsistent and erroneous behavior in
-kernel code, such as using slab free functions on kmalloc'ed memory or
-allocating less memory than requested (but not truly failed allocations).
-
-kmemtrace also makes provisions for tracing on some arch and analysing the
-data on another.
-
-II. Design and goals
-====================
-
-kmemtrace was designed to handle rather large amounts of data. Thus, it uses
-the relay interface to export whatever is logged to userspace, which then
-stores it. Analysis and reporting is done asynchronously, that is, after the
-data is collected and stored. By design, it allows one to log and analyse
-on different machines and different arches.
-
-As of writing this, the ABI is not considered stable, though it might not
-change much. However, no guarantees are made about compatibility yet. When
-deemed stable, the ABI should still allow easy extension while maintaining
-backward compatibility. This is described further in Documentation/ABI.
-
-Summary of design goals:
-	- allow logging and analysis to be done across different machines
-	- be fast and anticipate usage in high-load environments (*)
-	- be reasonably extensible
-	- make it possible for GNU/Linux distributions to have kmemtrace
-	included in their repositories
-
-(*) - one of the reasons Pekka Enberg's original userspace data analysis
-    tool's code was rewritten from Perl to C (although this is more than a
-    simple conversion)
-
-
-III. Quick usage guide
-======================
-
-1) Get a kernel that supports kmemtrace and build it accordingly (i.e. enable
-CONFIG_KMEMTRACE).
-
-2) Get the userspace tool and build it:
-$ git clone git://repo.or.cz/kmemtrace-user.git		# current repository
-$ cd kmemtrace-user/
-$ ./autogen.sh
-$ ./configure
-$ make
-
-3) Boot the kmemtrace-enabled kernel if you haven't, preferably in the
-'single' runlevel (so that relay buffers don't fill up easily), and run
-kmemtrace:
-# '$' does not mean user, but root here.
-$ mount -t debugfs none /sys/kernel/debug
-$ mount -t proc none /proc
-$ cd path/to/kmemtrace-user/
-$ ./kmemtraced
-Wait a bit, then stop it with CTRL+C.
-$ cat /sys/kernel/debug/kmemtrace/total_overruns	# Check if we didn't
-							# overrun, should
-							# be zero.
-$ (Optionally) [Run kmemtrace_check separately on each cpu[0-9]*.out file to
-		check its correctness]
-$ ./kmemtrace-report
-
-Now you should have a nice and short summary of how the allocator performs.

-IV. FAQ and known issues
-========================
-
-Q: 'cat /sys/kernel/debug/kmemtrace/total_overruns' is non-zero, how do I fix
-this? Should I worry?
-A: If it's non-zero, this affects kmemtrace's accuracy, depending on how
-large the number is. You can fix it by supplying a higher
-'kmemtrace.subbufs=N' kernel parameter.
----
-
-Q: kmemtrace_check reports errors, how do I fix this? Should I worry?
-A: This is a bug and should be reported. It can occur for a variety of
-reasons:
-	- possible bugs in relay code
-	- possible misuse of relay by kmemtrace
-	- timestamps being collected unorderly
-Or you may fix it yourself and send us a patch.
----
-
-Q: kmemtrace_report shows many errors, how do I fix this? Should I worry?
-A: This is a known issue and I'm working on it. These might be true errors
-in kernel code, which may have inconsistent behavior (e.g. allocating memory
-with kmem_cache_alloc() and freeing it with kfree()). Pekka Enberg pointed
-out this behavior may work with SLAB, but may fail with other allocators.
-
-It may also be due to lack of tracing in some unusual allocator functions.
-
-We don't want bug reports regarding this issue yet.

+
+* Overview
+
+The Multifunction Composite Gadget (or g_multi) is a composite gadget
+that makes extensive use of the composite framework to provide
+a... multifunction gadget.
+
+In it's standard configuration it provides a single USB configuration
+with RNDIS[1] (that is Ethernet), USB CDC[2] ACM (that is serial) and
+USB Mass Storage functions.
+
+A CDC ECM (Ethernet) function may be turned on via a Kconfig option
+and RNDIS can be turned off.  If they are both enabled the gadget will
+have two configurations -- one with RNDIS and another with CDC ECM[3].
+
+Please not that if you use non-standard configuration (that is enable
+CDC ECM) you may need to change vendor and/or product ID.
+
+* Host drivers
+
+To make use of the gadget one needs to make it work on host side --
+without that there's no hope of achieving anything with the gadget.
+As one might expect, things one need to do very from system to system.
+
+** Linux host drivers
+
+Since the gadget uses standard composite framework and appears as such
+to Linux host it does not need any additional drivers on Linux host
+side.  All the functions are handled by respective drivers developed
+for them.
+
+This is also true for two configuration set-up with RNDIS
+configuration being the first one.  Linux host will use the second
+configuration with CDC ECM which should work better under Linux.
+
+** Windows host drivers
+
+For the gadget two work under Windows two conditions have to be met:
+
+*** Detecting as composite gadget
+
+First of all, Windows need to detect the gadget as an USB composite
+gadget which on its own have some conditions[4].  If they are met,
+Windows lets USB Generic Parent Driver[5] handle the device which then
+tries to much drivers for each individual interface (sort of, don't
+get into too many details).
+
+The good news is: you do not have to worry about most of the
+conditions!
+
+The only thing to worry is that the gadget has to have a single
+configuration so a dual RNDIS and CDC ECM gadget won't work unless you
+create a proper INF -- and of course, if you do submit it!
+
+*** Installing drivers for each function
+
+The other, trickier thing is making Windows install drivers for each
+individual function.
+
+For mass storage it is trivial since Windows detect it's an interface
+implementing USB Mass Storage class and selects appropriate driver.
+
+Things are harder with RDNIS and CDC ACM.
+
+**** RNDIS
+
+To make Windows select RNDIS drivers for the first function in the
+gadget, one needs to use the [[file:linux.inf]] file provided with this
+document.  It "attaches" Window's RNDIS driver to the first interface
+of the gadget.
+
+Please note, that while testing we encountered some issues[6] when
+RNDIS was not the first interface.  You do not need to worry abut it
+unless you are trying to develop your own gadget in which case watch
+out for this bug.
+
+**** CDC ACM
+
+Similarly, [[file:linux-cdc-acm.inf]] is provided for CDC ACM.
+
+**** Customising the gadget
+
+If you intend to hack the g_multi gadget be advised that rearranging
+functions will obviously change interface numbers for each of the
+functionality.  As an effect provided INFs won't work since they have
+interface numbers hard-coded in them (it's not hard to change those
+though[7]).
+
+This also means, that after experimenting with g_multi and changing
+provided functions one should change gadget's vendor and/or product ID
+so there will be no collision with other customised gadgets or the
+original gadget.
+
+Failing to comply may cause brain damage after wondering for hours why
+things don't work as intended before realising Windows have cached
+some drivers information (changing USB port may sometimes help plus
+you might try using USBDeview[8] to remove the phantom device).
+
+**** INF testing
+
+Provided INF files have been tested on Windows XP SP3, Windows Vista
+and Windows 7, all 32-bit versions.  It should work on 64-bit versions
+as well.  It most likely won't work on Windows prior to Windows XP
+SP2.
+
+** Other systems
+
+At this moment, drivers for any other systems have not been tested.
+Knowing how MacOS is based on BSD and BSD is an Open Source it is
+believed that it should (read: "I have no idea whether it will") work
+out-of-the-box.
+
+For more exotic systems I have even less to say...
+
+Any testing and drivers *are* *welcome*!

+ * It is expected that the OMAP PM code will use this information to

+ *
+ * omap_pm_set_min_clk_rate() differs from the clock code's
+ * clk_set_rate() in that it considers other constraints before taking
+ * any hardware action, and may change a system OPP rather than just a
+ * clock rate.  clk_set_rate() is intended to be a low-level
+ * interface.
+ *
+ * omap_pm_set_min_clk_rate() is easily open to abuse.  A better API
+ * would be something like "omap_pm_set_min_dev_performance()";
+ * however, there is no easily-generalizable concept of performance
+ * that applies to all devices.  Only a device (and possibly the
+ * device subsystem) has both the subsystem-specific knowledge, and
+ * the hardware IP block-specific knowledge, to translate a constraint
+ * on "touchscreen sampling accuracy" or "number of pixels or polygons
+ * rendered per second" to a clock rate.  This translation can be
+ * dependent on the hardware IP block's revision, or firmware version,
+ * and the driver is the only code on the system that has this
+ * information and can know how to translate that into a clock rate.
+ *
+ * The intended use-case for this function is for userspace or other
+ * kernel code to communicate a particular performance requirement to
+ * a subsystem; then for the subsystem to communicate that requirement
+ * to something that is meaningful to the device driver; then for the
+ * device driver to convert that requirement to a clock rate, and to
+ * then call omap_pm_set_min_clk_rate().
+ *
+ * Users of this function (such as device drivers) should not simply
+ * call this function with some high clock rate to ensure "high
+ * performance."  Rather, the device driver should take a performance
+ * constraint from its subsystem, such as "render at least X polygons
+ * per second," and use some formula or table to convert that into a
+ * clock rate constraint given the hardware type and hardware
+ * revision.  Device drivers or subsystems should not assume that they
+ * know how to make a power/performance tradeoff - some device use
+ * cases may tolerate a lower-fidelity device function for lower power
+ * consumption; others may demand a higher-fidelity device function,
+ * no matter what the power consumption.
+ *
+ * Multiple calls to omap_pm_set_min_clk_rate() will replace the
+ * previous rate value for the device @dev.  To remove the minimum clock

+
+	  If you are compiling a kernel which will never run on a

+	  kernel boot arguments with the kernel itself (that is,
+	  to not rely on the boot loader to provide them.)
+
+	  To compile command line arguments into the kernel,
+	  set this option to 'Y', then fill in the

+	  command line at boot time, it is appended to this string to
+	  form the full kernel command line, when the system boots.
+
+	  However, you can use the CONFIG_CMDLINE_OVERRIDE option to
+	  change this behavior.
+
+	  In most cases, the command line (whether built-in or provided
+	  by the boot loader) should specify the device for the root
+	  file system.
+
+config CMDLINE_OVERRIDE

+	help
+	  Write kernel log output directly via the hypervisor console.
+
+	  This is useful for kernel debugging when your machine crashes very
+	  early before the console code is initialized. For normal operation

+ * the kernel task doesn't need to take any more interrupts.  At that
+ * point it's then necessary to explicitly reinstall it when context
+ * switching back to the original mm.
+ *
+ * On Tile, we have to do a page-table install whenever DMA is enabled,
+ * so in that case lazy mode doesn't help anyway.  And more generally,
+ * we have efficient per-page TLB shootdown, and don't expect to spend
+ * that much time in kernel tasks in general, so just leaving the
+ * kernel task borrowing the old page table, but handling TLB
+ * shootdowns, is a reasonable thing to do.  And importantly, this
+ * lets us use the hypervisor's internal APIs for TLB shootdown, which
+ * means we don't have to worry about having TLB shootdowns blocked

+ * read_barrier_depends - Flush all pending reads that subsequents reads

+ *
+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier.  All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads.  This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies.  See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ *	CPU 0				CPU 1
+ *
+ *	b = 2;
+ *	memory_barrier();
+ *	p = &b;				q = p;
+ *					read_barrier_depends();
+ *					d = *q;
+ * </programlisting>
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends().  However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ *	CPU 0				CPU 1
+ *
+ *	a = 2;
+ *	memory_barrier();
+ *	b = 3;				y = b;
+ *					read_barrier_depends();
+ *					x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b".  Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
+ * in cases like this where there are no data dependencies.

+ *  the hypervisor, and are normally handled directly by the client;
+ *  when these occur in a client's interrupt critical section, they must
+ *  be delivered through the downcall mechanism.
+ *
+ *  A downcall is initially delivered to the client as an INTCTRL_1
+ *  interrupt.  Upon entry to the INTCTRL_1 vector, the client must
+ *  immediately invoke the hv_downcall_dispatch service.  This service
+ *  will not return; instead it will cause one of the client's actual
+ *  downcall-handling interrupt vectors to be entered.  The EX_CONTEXT
+ *  registers in the client will be set so that when the client irets,
+ *  it will return to the code which was interrupted by the INTCTRL_1
+ *  interrupt.
+ *
+ *  Under some circumstances, the firing of INTCTRL_1 can race with
+ *  the lowering of a device interrupt.  In such a case, the
+ *  hv_downcall_dispatch service may issue an iret instruction instead
+ *  of entering one of the client's actual downcall-handling interrupt
+ *  vectors.  This will return execution to the location that was
+ *  interrupted by INTCTRL_1.
+ *
+ *  Any saving of registers should be done by the actual handling
+ *  vectors; no registers should be changed by the INTCTRL_1 handler.
+ *  In particular, the client should not use a jal instruction to invoke
+ *  the hv_downcall_dispatch service, as that would overwrite the client's
+ *  lr register.  Note that the hv_downcall_dispatch service may overwrite
+ *  one or more of the client's system save registers.
+ *
+ *  The client must not modify the INTCTRL_1_STATUS SPR.  The hypervisor
+ *  will set this register to cause a downcall to happen, and will clear
+ *  it when no further downcalls are pending.
+ *
+ *  When a downcall vector is entered, the INTCTRL_1 interrupt will be
+ *  masked.  When the client is done processing a downcall, and is ready
+ *  to accept another, it must unmask this interrupt; if more downcalls
+ *  are pending, this will cause the INTCTRL_1 vector to be reentered.
+ *  Currently the following interrupt vectors can be entered through a
+ *  downcall:
+ *
+ *  INT_MESSAGE_RCV_DWNCL   (hypervisor message available)
+ *  INT_DMATLB_MISS_DWNCL   (DMA TLB miss)

+ *
+ * Support routines for atomic operations.  Each function takes:
+ *
+ * r0: address to manipulate
+ * r1: pointer to atomic lock guarding this operation (for FUTEX_LOCK_REG)
+ * r2: new value to write, or for cmpxchg/add_unless, value to compare against
+ * r3: (cmpxchg/xchg_add_unless) new value to write or add;
+ *     (atomic64 ops) high word of value to write
+ * r4/r5: (cmpxchg64/add_unless64) new value to write or add
+ *
+ * The 32-bit routines return a "struct __get_user" so that the futex code
+ * has an opportunity to return -EFAULT to the user if needed.
+ * The 64-bit routines just return a "long long" with the value,
+ * since they are only used from kernel space and don't expect to fault.
+ * Support for 16-bit ops is included in the framework but we don't provide
+ * any (x86_64 has an atomic_inc_short(), so we might want to some day).
+ *
+ * Note that the caller is advised to issue a suitable L1 or L2
+ * prefetch on the address being manipulated to avoid extra stalls.
+ * In addition, the hot path is on two icache lines, and we start with
+ * a jump to the second line to make sure they are both in cache so
+ * that we never stall waiting on icache fill while holding the lock.
+ * (This doesn't work out with most 64-bit ops, since they consume
+ * too many bundles, so may take an extra i-cache stall.)
+ *
+ * These routines set the INTERRUPT_CRITICAL_SECTION bit, just
+ * like sys_cmpxchg(), so that NMIs like PERF_COUNT will not interrupt
+ * the code, just page faults.
+ *
+ * If the load or store faults in a way that can be directly fixed in
+ * the do_page_fault_ics() handler (e.g. a vmalloc reference) we fix it
+ * directly, return to the instruction that faulted, and retry it.
+ *
+ * If the load or store faults in a way that potentially requires us
+ * to release the atomic lock, then retry (e.g. a migrating PTE), we
+ * reset the PC in do_page_fault_ics() to the "tns" instruction so
+ * that on return we will reacquire the lock and restart the op.  We
+ * are somewhat overloading the exception_table_entry notion by doing
+ * this, since those entries are not normally used for migrating PTEs.
+ *
+ * If the main page fault handler discovers a bad address, it will see
+ * the PC pointing to the "tns" instruction (due to the earlier
+ * exception_table_entry processing in do_page_fault_ics), and
+ * re-reset the PC to the fault handler, atomic_bad_address(), which
+ * effectively takes over from the atomic op and can either return a
+ * bad "struct __get_user" (for user addresses) or can just panic (for
+ * bad kernel addresses).
+ *
+ * Note that if the value we would store is the same as what we
+ * loaded, we bypass the load.  Other platforms with true atomics can
+ * make the guarantee that a non-atomic __clear_bit(), for example,
+ * can safely race with an atomic test_and_set_bit(); this example is
+ * from bit_spinlock.h in slub_lock() / slub_unlock().  We can't do
+ * that on Tile since the "atomic" op is really just a
+ * read/modify/write, and can race with the non-atomic
+ * read/modify/write.  However, if we can short-circuit the write when
+ * it is not needed, in the atomic case, we avoid the race.

- *  - When the cycleOffset field wraps around to zero, the cycleCount field is

- *  - Occasionally, the entire register reads zero.
- *
- * To catch these, we read the register three times and ensure that the

- * less than twice the other.  Furthermore, any negative difference indicates an

+ * Driver for USB Windows Media Center Ed. eHome Infrared Transceivers
+ *
+ * Copyright (c) 2010 by Jarod Wilson <jarod@redhat.com>
+ *
+ * Based on the original lirc_mceusb and lirc_mceusb2 drivers, by Dan
+ * Conti, Martin Blatter and Daniel Melander, the latter of which was
+ * in turn also based on the lirc_atiusb driver by Paul Miller. The
+ * two mce drivers were merged into one by Jarod Wilson, with transmit
+ * support for the 1st-gen device added primarily by Patrick Calhoun,
+ * with a bit of tweaks by Jarod. Debugging improvements and proper
+ * support for what appears to be 3rd-gen hardware added by Jarod.
+ * Initial port from lirc driver to ir-core drivery by Jarod, based
+ * partially on a port to an earlier proposed IR infrastructure by
+ * Jon Smirl, which included enhancements and simplifications to the
+ * incoming IR buffer parsing routines.

- *  STV0680 USB Camera Driver, by Kevin Sisson (kjsisson@bellsouth.net)
- *
- * Thanks to STMicroelectronics for information on the usb commands, and
- * to Steve Miller at STM for his help and encouragement while I was
- * writing this driver.
- *
- * This driver is based heavily on the
- * Endpoints (formerly known as AOX) se401 USB Camera Driver
- * Copyright (c) 2000 Jeroen B. Vreeken (pe1rxq@amsat.org)
- *
- * Still somewhat based on the Linux ov511 driver.

- * Free Software Foundation; either version 2 of the License, or (at your
- * option) any later version.

- * along with this program; if not, write to the Free Software Foundation,
- * Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
- *
- * History:
- * ver 0.1 October, 2001. Initial attempt.
- *
- * ver 0.2 November, 2001. Fixed asbility to resize, added brightness
- *                         function, made more stable (?)
- *
- * ver 0.21 Nov, 2001.     Added gamma correction and white balance,
- *                         due to Alexander Schwartz. Still trying to
- *                         improve stablility. Moved stuff into stv680.h
- *
- * ver 0.22 Nov, 2001.	   Added sharpen function (by Michael Sweet,
- *                         mike@easysw.com) from GIMP, also used in pencam.
- *                         Simple, fast, good integer math routine.
- *
- * ver 0.23 Dec, 2001 (gkh)
- * 			   Took out sharpen function, ran code through
- * 			   Lindent, and did other minor tweaks to get
- * 			   things to work properly with 2.5.1
- *
- * ver 0.24 Jan, 2002 (kjs)
- *                         Fixed the problem with webcam crashing after
- *                         two pictures. Changed the way pic is halved to
- *                         improve quality. Got rid of green line around
- *                         frame. Fix brightness reset when changing size
- *                         bug. Adjusted gamma filters slightly.
- *
- * ver 0.25 Jan, 2002 (kjs)
- *			   Fixed a bug in which the driver sometimes attempted
- *			   to set to a non-supported size. This allowed
- *			   gnomemeeting to work.
- *			   Fixed proc entry removal bug.

+ * domain.
+ *
+ * MRC requires extra work for use with CCK. You need to align the antenna

+ * You need aligment of signals as CCK is in time domain, so addition can cancel
+ * your signal completely if phase is 180 degrees (think of adding sine waves).
+ * You also need to remove noise before the addition and this is where ANI
+ * MRC CCK comes into play. One of the antenna inputs may be stronger but
+ * lower SNR, so just adding after alignment can be dangerous.
+ *
+ * Regardless of alignment in time, the antenna signals add constructively after
+ * FFT and improve your reception. For more information:

+/*
+ * Some Intel Ibex Peak based platforms support so-called "intelligent
+ * power sharing", which allows the CPU and GPU to cooperate to maximize
+ * performance within a given TDP (thermal design point).  This driver
+ * performs the coordination between the CPU and GPU, monitors thermal and
+ * power statistics in the platform, and initializes power monitoring
+ * hardware.  It also provides a few tunables to control behavior.  Its
+ * primary purpose is to safely allow CPU and GPU turbo modes to be enabled
+ * by tracking power and thermal budget; secondarily it can boost turbo
+ * performance by allocating more power or thermal budget to the CPU or GPU
+ * based on available headroom and activity.
+ *
+ * The basic algorithm is driven by a 5s moving average of tempurature.  If
+ * thermal headroom is available, the CPU and/or GPU power clamps may be
+ * adjusted upwards.  If we hit the thermal ceiling or a thermal trigger,
+ * we scale back the clamp.  Aside from trigger events (when we're critically
+ * close or over our TDP) we don't adjust the clamps more than once every
+ * five seconds.
+ *
+ * The thermal device (device 31, function 6) has a set of registers that
+ * are updated by the ME firmware.  The ME should also take the clamp values
+ * written to those registers and write them to the CPU, but we currently
+ * bypass that functionality and write the CPU MSR directly.
+ *
+ * UNSUPPORTED:
+ *   - dual MCP configs
+ *
+ * TODO:
+ *   - handle CPU hotplug
+ *   - provide turbo enable/disable api
+ *   - make sure we can write turbo enable/disable reg based on MISC_EN
+ *

-	  This driver allows other kernel drivers access to the
-	  contents of the restricted access region control registers.
-
-	  The restricted access region control registers
-	  (rar_registers) are used to pass address and
-	  locking information on restricted access regions
-	  to other drivers that use restricted access regions.
-
-	  The restricted access regions are regions of memory
-	  on the Intel MID Platform that are not accessible to
-	  the x86 processor, but are accessible to dedicated
-	  processors on board peripheral devices.
-
-	  The purpose of the restricted access regions is to
-	  protect sensitive data from compromise by unauthorized
-	  programs running on the x86 processor.

+	   Say Y here is you want fanotify listeners to be able to make permissions
+	   decisions concerning filesystem events.  This is used by some fanotify
+	   listeners which need to scan files before allowing the system access to
+	   use those files.  This is used by some anti-malware vendors and by some
+	   hierarchical storage managent systems.
+
+	   If unsure, say N.

-/*
- * fsnotify inode mark locking/lifetime/and refcnting
- *
- * REFCNT:
- * The mark->refcnt tells how many "things" in the kernel currently are
- * referencing this object.  The object typically will live inside the kernel
- * with a refcnt of 2, one for each list it is on (i_list, g_list).  Any task
- * which can find this object holding the appropriete locks, can take a reference
- * and the object itself is guarenteed to survive until the reference is dropped.
- *
- * LOCKING:
- * There are 3 spinlocks involved with fsnotify inode marks and they MUST
- * be taken in order as follows:
- *
- * entry->lock
- * group->mark_lock
- * inode->i_lock
- *
- * entry->lock protects 2 things, entry->group and entry->inode.  You must hold
- * that lock to dereference either of these things (they could be NULL even with
- * the lock)
- *
- * group->mark_lock protects the mark_entries list anchored inside a given group
- * and each entry is hooked via the g_list.  It also sorta protects the
- * free_g_list, which when used is anchored by a private list on the stack of the
- * task which held the group->mark_lock.
- *
- * inode->i_lock protects the i_fsnotify_mark_entries list anchored inside a
- * given inode and each entry is hooked via the i_list. (and sorta the
- * free_i_list)
- *
- *
- * LIFETIME:
- * Inode marks survive between when they are added to an inode and when their
- * refcnt==0.
- *
- * The inode mark can be cleared for a number of different reasons including:
- * - The inode is unlinked for the last time.  (fsnotify_inode_remove)
- * - The inode is being evicted from cache. (fsnotify_inode_delete)
- * - The fs the inode is on is unmounted.  (fsnotify_inode_delete/fsnotify_unmount_inodes)
- * - Something explicitly requests that it be removed.  (fsnotify_destroy_mark_by_entry)
- * - The fsnotify_group associated with the mark is going away and all such marks
- *   need to be cleaned up. (fsnotify_clear_marks_by_group)
- *
- * Worst case we are given an inode and need to clean up all the marks on that
- * inode.  We take i_lock and walk the i_fsnotify_mark_entries safely.  For each
- * mark on the list we take a reference (so the mark can't disappear under us).
- * We remove that mark form the inode's list of marks and we add this mark to a
- * private list anchored on the stack using i_free_list;  At this point we no
- * longer fear anything finding the mark using the inode's list of marks.
- *
- * We can safely and locklessly run the private list on the stack of everything
- * we just unattached from the original inode.  For each mark on the private list
- * we grab the mark-> and can thus dereference mark->group and mark->inode.  If
- * we see the group and inode are not NULL we take those locks.  Now holding all
- * 3 locks we can completely remove the mark from other tasks finding it in the
- * future.  Remember, 10 things might already be referencing this mark, but they
- * better be holding a ref.  We drop our reference we took before we unhooked it
- * from the inode.  When the ref hits 0 we can free the mark.
- *
- * Very similarly for freeing by group, except we use free_g_list.
- *
- * This has the very interesting property of being able to run concurrently with
- * any (or all) other directions.

+ * fsnotify inode mark locking/lifetime/and refcnting
+ *
+ * REFCNT:
+ * The mark->refcnt tells how many "things" in the kernel currently are
+ * referencing this object.  The object typically will live inside the kernel
+ * with a refcnt of 2, one for each list it is on (i_list, g_list).  Any task
+ * which can find this object holding the appropriete locks, can take a reference
+ * and the object itself is guarenteed to survive until the reference is dropped.
+ *
+ * LOCKING:
+ * There are 3 spinlocks involved with fsnotify inode marks and they MUST
+ * be taken in order as follows:
+ *
+ * mark->lock
+ * group->mark_lock
+ * inode->i_lock
+ *
+ * mark->lock protects 2 things, mark->group and mark->inode.  You must hold
+ * that lock to dereference either of these things (they could be NULL even with
+ * the lock)
+ *
+ * group->mark_lock protects the marks_list anchored inside a given group
+ * and each mark is hooked via the g_list.  It also sorta protects the
+ * free_g_list, which when used is anchored by a private list on the stack of the
+ * task which held the group->mark_lock.
+ *
+ * inode->i_lock protects the i_fsnotify_marks list anchored inside a
+ * given inode and each mark is hooked via the i_list. (and sorta the
+ * free_i_list)
+ *
+ *
+ * LIFETIME:
+ * Inode marks survive between when they are added to an inode and when their
+ * refcnt==0.
+ *
+ * The inode mark can be cleared for a number of different reasons including:
+ * - The inode is unlinked for the last time.  (fsnotify_inode_remove)
+ * - The inode is being evicted from cache. (fsnotify_inode_delete)
+ * - The fs the inode is on is unmounted.  (fsnotify_inode_delete/fsnotify_unmount_inodes)
+ * - Something explicitly requests that it be removed.  (fsnotify_destroy_mark)
+ * - The fsnotify_group associated with the mark is going away and all such marks
+ *   need to be cleaned up. (fsnotify_clear_marks_by_group)
+ *
+ * Worst case we are given an inode and need to clean up all the marks on that
+ * inode.  We take i_lock and walk the i_fsnotify_marks safely.  For each
+ * mark on the list we take a reference (so the mark can't disappear under us).
+ * We remove that mark form the inode's list of marks and we add this mark to a
+ * private list anchored on the stack using i_free_list;  At this point we no
+ * longer fear anything finding the mark using the inode's list of marks.
+ *
+ * We can safely and locklessly run the private list on the stack of everything
+ * we just unattached from the original inode.  For each mark on the private list
+ * we grab the mark-> and can thus dereference mark->group and mark->inode.  If
+ * we see the group and inode are not NULL we take those locks.  Now holding all
+ * 3 locks we can completely remove the mark from other tasks finding it in the
+ * future.  Remember, 10 things might already be referencing this mark, but they
+ * better be holding a ref.  We drop our reference we took before we unhooked it
+ * from the inode.  When the ref hits 0 we can free the mark.
+ *
+ * Very similarly for freeing by group, except we use free_g_list.
+ *
+ * This has the very interesting property of being able to run concurrently with
+ * any (or all) other directions.

+/*
+ * Copyright 2009 Novell.  All Rights Reserved.
+ *
+ * IOQ is a generic shared-memory, lockless queue mechanism. It can be used
+ * in a variety of ways, though its intended purpose is to become the
+ * asynchronous communication path for virtual-bus drivers.
+ *
+ * The following are a list of key design points:
+ *
+ * #) All shared-memory is always allocated on explicitly one side of the
+ *    link.  This typically would be the guest side in a VM/VMM scenario.
+ * #) Each IOQ has the concept of "north" and "south" locales, where
+ *    north denotes the memory-owner side (e.g. guest).
+ * #) An IOQ is manipulated using an iterator idiom.
+ * #) Provides a bi-directional signaling/notification infrastructure on
+ *    a per-queue basis, which includes an event mitigation strategy
+ *    to reduce boundary switching.
+ * #) The signaling path is abstracted so that various technologies and
+ *    topologies can define their own specific implementation while sharing
+ *    the basic structures and code.

+/*
+ * To properly implement 64bits network statistics on 32bit and 64bit hosts,
+ * we provide a synchronization point, that is a noop on 64bit or UP kernels.
+ *
+ * Key points :
+ * 1) Use a seqcount on SMP 32bits, with low overhead.
+ * 2) Whole thing is a noop on 64bit arches or UP kernels.
+ * 3) Write side must ensure mutual exclusion or one seqcount update could
+ *    be lost, thus blocking readers forever.
+ *    If this synchronization point is not a mutex, but a spinlock or
+ *    spinlock_bh() or disable_bh() :
+ * 3.1) Write side should not sleep.
+ * 3.2) Write side should not allow preemption.
+ * 3.3) If applicable, interrupts should be disabled.
+ *
+ * 4) If reader fetches several counters, there is no guarantee the whole values
+ *    are consistent (remember point 1) : this is a noop on 64bit arches anyway)
+ *
+ * 5) readers are allowed to sleep or be preempted/interrupted : They perform
+ *    pure reads. But if they have to fetch many values, it's better to not allow
+ *    preemptions/interruptions to avoid many retries.
+ *
+ * 6) If counter might be written by an interrupt, readers should block interrupts.
+ *    (On UP, there is no seqcount_t protection, a reader allowing interrupts could
+ *     read partial values)
+ *
+ * 7) For softirq uses, readers can use u64_stats_fetch_begin_bh() and
+ *    u64_stats_fetch_retry_bh() helpers
+ *
+ * Usage :
+ *
+ * Stats producer (writer) should use following template granted it already got
+ * an exclusive access to counters (a lock is already taken, or per cpu
+ * data is used [in a non preemptable context])
+ *
+ *   spin_lock_bh(...) or other synchronization to get exclusive access
+ *   ...
+ *   u64_stats_update_begin(&stats->syncp);
+ *   stats->bytes64 += len; // non atomic operation
+ *   stats->packets64++;    // non atomic operation
+ *   u64_stats_update_end(&stats->syncp);
+ *
+ * While a consumer (reader) should use following template to get consistent
+ * snapshot for each variable (but no guarantee on several ones)
+ *
+ * u64 tbytes, tpackets;
+ * unsigned int start;
+ *
+ * do {
+ *         start = u64_stats_fetch_begin(&stats->syncp);
+ *         tbytes = stats->bytes64; // non atomic operation
+ *         tpackets = stats->packets64; // non atomic operation
+ * } while (u64_stats_fetch_retry(&stats->syncp, start));

+ * There is no strict promise about the base, although it tends to start
+ * at 0 on boot (but people really shouldn't rely on that).
+ *
+ * cpu_clock(i)       -- can be used from any context, including NMI.
+ * sched_clock_cpu(i) -- must be used with local IRQs disabled (implied by NMI)
+ * local_clock()      -- is cpu_clock() on the current cpu.
+ *
+ * How:
+ *
+ * The implementation either uses sched_clock() when
+ * !CONFIG_HAVE_UNSTABLE_SCHED_CLOCK, which means in that case the
+ * sched_clock() is assumed to provide these properties (mostly it means
+ * the architecture provides a globally synchronized highres time source).
+ *
+ * Otherwise it tries to create a semi stable clock from a mixture of other
+ * clocks, including:
+ *
+ *  - GTOD (clock monotomic)
  *  - sched_clock()
  *  - explicit idle events
  *
- * We use gtod as base and the unstable clock deltas. The deltas are filtered,
- * making it monotonic and keeping it within an expected window.
+ * We use GTOD as base and use sched_clock() deltas to improve resolution. The
+ * deltas are filtered to provide monotonicity and keeping it within an
+ * expected window.
  *
  * Furthermore, explicit sleep and wakeup hooks allow us to account for time
  * that is otherwise invisible (TSC gets stopped).
  *
- * The clock: sched_clock_cpu() is monotonic per cpu, and should be somewhat
- * consistent between cpus (never more than 2 jiffies difference).
+ *
+ * Notes:
+ *
+ * The !IRQ-safetly of sched_clock() and sched_clock_cpu() comes from things
+ * like cpufreq interrupts that can change the base clock (TSC) multiplier
+ * and cause funny jumps in time -- although the filtering provided by
+ * sched_clock_cpu() should mitigate serious artifacts we cannot rely on it
+ * in general since for !CONFIG_HAVE_UNSTABLE_SCHED_CLOCK we fully rely on

- * ftrace_preempt_disable - disable preemption scheduler safe

- * flag is checked. If this happens and the tracer calls
- * preempt_enable (after a disable), a schedule might take place
- * causing an infinite recursion.
- *
- * To prevent this, we read the need_resched flag before
- * disabling preemption. When we want to enable preemption we
- * check the flag, if it is set, then we call preempt_enable_no_resched.
- * Otherwise, we call preempt_enable.
- *
- * The rational for doing the above is that if need_resched is set
- * and we have yet to reschedule, we are either in an atomic location
- * (where we do not need to check for scheduling) or we are inside
- * the scheduler and do not want to resched.

+ * DOC: RX A-MPDU aggregation
+ *
+ * Aggregation on the RX side requires only implementing the

+ * block-ack sessions for RX aggregation.
+ *
+ * When RX aggregation is started by the peer, the driver is
+ * notified via @ampdu_action function, with the
+ * %IEEE80211_AMPDU_RX_START action, and may reject the request
+ * in which case a negative response is sent to the peer, if it
+ * accepts it a positive response is sent.
+ *
+ * While the session is active, the device/driver are required
+ * to de-aggregate frames and pass them up one by one to mac80211,
+ * which will handle the reorder buffer.
+ *
+ * When the aggregation session is stopped again by the peer or
+ * ourselves, the driver's @ampdu_action function will be called
+ * with the action %IEEE80211_AMPDU_RX_STOP. In this case, the
+ * call must not fail.

  *
  * Aggregation on the TX side requires setting the hardware flag
- * %IEEE80211_HW_AMPDU_AGGREGATION as well as, if present, the @ampdu_queues
- * hardware parameter to the number of hardware AMPDU queues. If there are no
- * hardware queues then the driver will (currently) have to do all frame
- * buffering.
+ * %IEEE80211_HW_AMPDU_AGGREGATION. The driver will then be handed
+ * packets with a flag indicating A-MPDU aggregation. The driver
+ * or device is responsible for actually aggregating the frames,
+ * as well as deciding how many and which to aggregate.
  *
- * When TX aggregation is started by some subsystem (usually the rate control
- * algorithm would be appropriate) by calling the
- * ieee80211_start_tx_ba_session() function, the driver will be notified via
- * its @ampdu_action function, with the %IEEE80211_AMPDU_TX_START action.

+ * notified via its @ampdu_action function, with the
+ * %IEEE80211_AMPDU_TX_START action.
  *
  * In response to that, the driver is later required to call the

- * function, which will start the aggregation session.
+ * ieee80211_start_tx_ba_cb_irqsafe() function, which will really
+ * start the aggregation session after the peer has also responded.
+ * If the peer responds negatively, the session will be stopped
+ * again right away. Note that it is possible for the aggregation
+ * session to be stopped before the driver has indicated that it
+ * is done setting it up, in which case it must not indicate the
+ * setup completion.
  *
- * Similarly, when the aggregation session is stopped by
- * ieee80211_stop_tx_ba_session(), the driver's @ampdu_action function will
- * be called with the action %IEEE80211_AMPDU_TX_STOP. In this case, the
- * call must not fail, and the driver must later call ieee80211_stop_tx_ba_cb()
- * (or ieee80211_stop_tx_ba_cb_irqsafe()).
+ * Also note that, since we also need to wait for a response from
+ * the peer, the driver is notified of the completion of the
+ * handshake by the %IEEE80211_AMPDU_TX_OPERATIONAL action to the
+ * @ampdu_action callback.

-/*
- * tomoyo_alias_list is used for holding list of symlink's pathnames which are
- * allowed to be passed to an execve() request. Normally, the domainname which
- * the current process will belong to after execve() succeeds is calculated
- * using dereferenced pathnames. But some programs behave differently depending
- * on the name passed to argv[0]. For busybox, calculating domainname using
- * dereferenced pathnames will cause all programs in the busybox to belong to
- * the same domain. Thus, TOMOYO provides a way to allow use of symlink's
- * pathname for checking execve()'s permission and calculating domainname which
- * the current process will belong to after execve() succeeds.
- *
- * An entry is added by
- *
- * # echo 'alias /bin/busybox /bin/cat' > \
- *                            /sys/kernel/security/tomoyo/exception_policy
- *
- * and is deleted by
- *
- * # echo 'delete alias /bin/busybox /bin/cat' > \
- *                            /sys/kernel/security/tomoyo/exception_policy
- *
- * and all entries are retrieved by
- *
- * # grep ^alias /sys/kernel/security/tomoyo/exception_policy
- *
- * In the example above, if /bin/cat is a symlink to /bin/busybox and execution
- * of /bin/cat is requested, permission is checked for /bin/cat rather than
- * /bin/busybox and domainname which the current process will belong to after
- * execve() succeeds is calculated using /bin/cat rather than /bin/busybox .
