Commit 6680ec68eff47d36f67b4351bc9836fd6cba9532
(tuntap: hardware vlan tx support) breaks the truncated packet signal by nev
return a length greater than iov length in tun_put_user(). This patch fixes
by always return the length of packet plus possible vlan header. Caller can
detect the truncated packet by comparing the return value and the size of io
length.

Renesas R-Car development boards use KSZ8041RNLI PHY which for some reason has
ID of 0x00221537 that is not documented for KSZ8041-family PHYs and does not
match the documented ID of 0x0022151x (where 'x' is the revision). We have
to add the new #define PHY_ID_* and new ksphy_driver[] entry, almost the same
as KSZ8041 one, differing only in the 'phy_id' and 'name' fields.

The new tg3 driver leaves REG_BASE_ADDR (PCI config offset 120)
uninitialized. From power on reset this register may have garbage in it. The
Register Base Address register defines the device local address of a
register. The data pointed to by this location is read or written using
the Register Data register (PCI config offset 128). When REG_BASE_ADDR has
garbage any read or write of Register Data Register (PCI 128) will cause the
PCI bus to lock up. The TCO watchdog will fire and bring down the system.

macvtap_put_user() never return a value grater than iov length, this in fact
bypasses the truncated checking in macvtap_recvmsg(). Fix this by always
returning the size of packet plus the possible vlan header to let the truncated

Ben Hutchings says:
====================
Several fixes for the PTP hardware support added in 3.7:
1. Fix filtering of PTP packets on the TX path to be robust against bad
header lengths.
2. Limit logging on the RX path in case of a PTP packet flood, partly
from Laurence Evans.
3. Disable PTP hardware when the interface is down so that we don't
receive RX timestamp events, from Alexandre Rames.
4. Maintain clock frequency adjustment when a time offset is applied.
Also fixes for the SFC9100 family support added in 3.12:
5. Take the RX prefix length into account when applying NET_IP_ALIGN,
from Andrew Rybchenko.
6. Work around a bug that breaks communication between the driver and
firmware, from Robert Stonehouse.
Please also queue these up for the appropriate stable branches.

The module parameter stats_current_allocated_bytes in dm-mod is
read-only. This parameter informs the user about memory
consumption. It is not supposed to be changed by the user.
However, despite being read-only, this parameter can be set on
modprobe or insmod command line:
modprobe dm-mod stats_current_allocated_bytes=12345
The kernel doesn't expect that this variable can be non-zero at module
initialization and if the user sets it, it results in warning.
This patch initializes the variable in the module init routine, so
that user-supplied value is ignored.

The sun4i-emac driver uses devm_request_irq at .ndo_open time, but relies on
the managed device mechanism to actually free it. This causes an issue whenever
someone wants to restart the interface, the interrupt still being held, and not
yet released.
Fall back to using the regular request_irq at .ndo_open time, and introduce a
free_irq during .ndo_stop.

Commit f494a9c6b1b6dd9a9f21bbb75d9210d478eeb498 ("dm cache: cache
shrinking support") broke cache resizing support.
dm_cache_resize() is called with cache->cache_size before it gets
updated to new_size, so it is a no-op. But the dm-cache superblock is
updated with the new_size even though the backing dm-array is not
resized. Fix this by passing the new_size to dm_cache_resize().

Micro benchmarks that repeatedly issued IO to a single block were
failing to cause a promotion from the origin device to the cache. Fix
this by not updating the stats during map() if -EWOULDBLOCK will be
returned.
The mq policy will only update stats, consider migration, etc, once per
tick period (a unit of time established between dm-cache core and the
policies).
When the IO thread calls the policy's map method, if it would like to
migrate the associated block it returns -EWOULDBLOCK, the IO then gets
handed over to a worker thread which handles the migration. The worker
thread calls map again, to check the migration is still needed (avoids a
race among other things). *BUT*, before this fix, if we were still in
the same tick period the stats were already updated by the previous map
call -- so the migration would no longer be requested.

A thin-pool may be in read-only mode because the pool's data or metadata
space was exhausted. To allow for recovery, by adding more space to the
pool, we must allow a pool to transition from PM_READ_ONLY to PM_WRITE
mode. Otherwise, running out of space will render the pool permanently
read-only.

If the thin-pool transitioned to fail mode and the thin-pool's table
were reloaded for some reason: the new table's default pool mode would
be read-write, though it will transition to fail mode during resume.
When the pool mode transitions directly from PM_WRITE to PM_FAIL we need
to re-establish the intermediate read-only state in both the metadata
and persistent-data block manager (as is usually done with the normal
pool mode transition sequence: PM_WRITE -> PM_READ_ONLY -> PM_FAIL).

Commit 2fc48021f4afdd109b9e52b6eef5db89ca80bac7 ("dm persistent
metadata: add space map threshold callback") introduced a regression
to the metadata block allocation path that resulted in errors being
ignored. This regression was uncovered by running the following
device-mapper-test-suite test:
dmtest run --suite thin-provisioning -n /exhausting_metadata_space_causes_fail_mode/
The ignored error codes in sm_metadata_new_block() could crash the
kernel through use of either the dm-thin or dm-cache targets, e.g.:
device-mapper: thin: 253:4: reached low water mark for metadata device: sending event.
device-mapper: space map metadata: unable to allocate new metadata block

There is a possible leak of snapshot space in case of crash.
The reason for space leaking is that chunks in the snapshot device are
allocated sequentially, but they are finished (and stored in the metadata)
out of order, depending on the order in which copying finished.
For example, supposed that the metadata contains the following records
SUPERBLOCK
METADATA (blocks 0 ... 250)
DATA 0
DATA 1
DATA 2
...
DATA 250
Now suppose that you allocate 10 new data blocks 251-260. Suppose that
copying of these blocks finish out of order (block 260 finished first
and the block 251 finished last). Now, the snapshot device looks like
this:
SUPERBLOCK
METADATA (blocks 0 ... 250, 260, 259, 258, 257, 256)
DATA 0
DATA 1
DATA 2
...
DATA 250
DATA 251
DATA 252
DATA 253
DATA 254
DATA 255
METADATA (blocks 255, 254, 253, 252, 251)
DATA 256
DATA 257
DATA 258
DATA 259
DATA 260
Now, if the machine crashes after writing the first metadata block but
before writing the second metadata block, the space for areas DATA 250-255
is leaked, it contains no valid data and it will never be used in the
future.
This patch makes dm-snapshot complete exceptions in the same order they
were allocated, thus fixing this bug.
Note: when backporting this patch to the stable kernel, change the version
field in the following way:
* if version in the stable kernel is {1, 11, 1}, change it to {1, 12, 0}
* if version in the stable kernel is {1, 10, 0} or {1, 10, 1}, change it
to {1, 10, 2}
Userspace reads the version to determine if the bug was fixed, so the
version change is needed.

Commit dc77523c5da5513df1bbc74db2a522a94f4cec0e ensured that m.offset is
only set for the MMAP memory mode by calling __setup_offsets only for that
mode.
However, __setup_offsets also initializes the length fields, and that should
be done regardless of the memory mode. Because of that change the v4l2-ctl
test application fails for the USERPTR mode.
This fix creates a __setup_lengths function that sets the length, and
__setup_offsets just sets the offset and no longer touches the length.

Restore previous layout of sysfs attributes that was broken by commit
3778a2129bcce84f684cc0017ed20d2524afd289 (input: serio: remove bus usage of
dev_attrs) which moved all serio device attributes into 'id' group, when
only 'type', 'proto', 'id', and 'extra' should be in 'id' group and the
rest of attributes should be attached directly to the device.

The "screen" properties : depth, width, height, linebytes need
to be converted to the host endian order when read from the device

The offb_init_palette_hacks() routine also made assumption on the

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
A rather big fix for a regression where we have dropped omap4 hwmod
data earlier but are not initializing it from device tree. In addition
to this fix we eventually also be fix the issues in the .dts files
and drivers, but that's too intrusive for the -rc cycle and must be
done later on.
Also a fix for a regression where we now are wrongly trying to initialize
devices on secure omaps like n900 and n9* when booted using device tree.
We need to set aes, sham and timer12 to disabled mode for secure
devices as they are claimed by the firmware running in the secure mode.
And two more legacy booting vs device tree based booting fixes for
am3517 that I did not notice earlier until Nishant Menon reported
these to me few days ago. With these we're good to go having v3.13
working both for legacy booting and device tree based booting, and we
can then go ahed and drop the legacy booting for mach-omap2 for v3.14.

When not aggregating packets, fi->framelen should be passed in as length
to calculate the duration. Before the tx path rework, ath_tx_fill_desc
was called for either one aggregate, or one single frame, with the
length of the packet or the aggregate as a parameter.
After the rework, ath_tx_sched_aggr can pass a burst of single frames to
ath_tx_fill_desc and sets len=0.
Fix broken duration calculation by overriding the length in ath_tx_fill_desc
before passing it to ath_buf_set_rate.
