Add support for design which has an em2863/tvp5150 and uses the standard
empia USB ID. In Sander's case, it was branded as an "Eminent model EM3705"
Thanks to Sander Van Ginkel for testing and help debugging the support.

This patch adds the capability to use the usb debug port with the
kernel debugger. It is also still possible to use this functionality
with or without the earlyprintk=dbgpX. It is possible to use the
kgdbwait boot argument to debug very early in the kernel start up code.
There are two ways to use this driver extension with a kernel boot argument.
1) kgdbdbgp=# -- Where # is the number of the usb debug controller
You must use sysrq-g to break into the kernel debugger on another
connection type other than the dbgp.
2) kgdbdbgp=#debugControlNum#,#Seconds#
In this mode, the usb debug port is polled every #Seconds# for
character input. It is possible to use gdb or press control-c to
break into the kernel debugger.
From the implementation perspective there are 3 high level changes.
1) Allow variable retries for the the hardware via dbgp_bulk_read().
The amount of retries for the dbgp_bulk_read() needed to be
variable instead of fixed. We do not want to poll at all when the
kernel is operating in interrupt driven mode. The polling only
occurs if the kernel was booted when specifying some number of
seconds via the kgdbdbgp boot argument (IE kgdbdbgp=0,1). In this
case the loop count is reduced to 1 so as introduce the smallest
amount of latency as possible.
2) Save the bulk IN endpoint address for use by the kgdb code.
3) The addition of the kgdb interface code.
This consisted of adding in a character read function for the dbgp
as well as a polling thread to allow the dbgp to interrupt the
kernel execution. The rest is the typical kgdb I/O api.

The ekgdboc= differs from kgdboc= in that you can begin debuggin as
soon as the exceptions are setup and the kgdb I/O driver is available,
instead of waiting until the tty subsystem is available.

This patch adds in the kdb PS/2 keyboard driver. This was mostly a
direct port from the original kdb where I cleaned up the code against
checkpatch.pl and added the glue to stitch it into kgdb.
This patch also enables early kdb debug via kgdbwait and the keyboard.
All the access to configure kdb using either a serial console or the
keyboard is done via kgdboc.
If you want to use only the keyboard and want to break in early you
would add to your kernel command arguments:
kgdboc=kbd kgdbwait
If you wanted serial and or the keyboard access you could use:
kgdboc=kbd,ttyS0
You can also configure kgdboc as a kernel module or at run time with
the sysfs where you can activate and deactivate kgdb.
Turn it on:
echo kbd,ttyS0 > /sys/module/kgdboc/parameters/kgdboc
Turn it off:
echo "" > /sys/module/kgdboc/parameters/kgdboc

This Patch adds support for Kone gaming mouse from Roccat.
It provides access to profiles, settings, firmware, weight,
actual settings etc. through sysfs attributes.
Event handling of this mouse differs from standard hid behaviour
in that tilt button press is reported in each move event which
results in strange behaviour if not handled by the driver.
This is a heavily reworked version of the previously introduced driver.
The changes include most of the previously raised concerns,
memory leak and other fixes, code cleanups, adoption of additional
achieved knowlege about the hardware and is (IMHO) a much better version
than before even when I exchanged reduced USB-IO with a bigger memory
consumption.
I refused to implement one mentioned point:
Removing the 'just-because-we-can' attributes. Motivation:
Reading the clipped in weight: I'm no gamer and can't determine the
usefulness of this feature but if the manufacturer implements such a
feature it might make sense to someone and I would unwillingly limit the
functionality besides its such a small feature.
Reading the actual profile and dpi settings: Here I can testify that one
can get lost of the actual settings when switching back and forth.
The manufacturers windows driver has the ability for on-screen-display
of the values and there is a mouse in the market that has an lcd on the
underside of it to show these values. So I think this feature makes sense
not only for me and shouldn't be removed.

Create convenience symlinks in sysfs, linking slots to device
functions, and vice versa. These links make it easier for users to
figure out which devices actually live in what slots.
For example:
sapphire:/sys/bus/pci/slots # ls
1 10 2 3 4 5 6 7 8 9
sapphire:/sys/bus/pci/slots # ls -l 3
total 0
-r--r--r-- 1 root root 65536 Aug 18 14:10 address
lrwxrwxrwx 1 root root 0 Aug 18 14:10 function0 ->
../../../../devices/pci0000:23/0000:23:01.0
lrwxrwxrwx 1 root root 0 Aug 18 14:10 function1 ->
../../../../devices/pci0000:23/0000:23:01.1
sapphire:/sys/bus/pci/slots # ls -l 3/function0/slot
lrwxrwxrwx 1 root root 0 Aug 18 14:13 3/function0/slot ->
../../../bus/pci/slots/3
The original form of this patch was written by Matthew Wilcox,
and was enhanced to include links from the sysfs slots/ directory
pointing back at the device functions.
