[git pull 0/7] Another input update for 2.6.15

[Dmitry Torokhov]

Hi Linus,

Please do a pull from:

	rsync://rsync.kernel.org/pub/scm/linux/kernel/git/dtor/input.git/
or
	master.kernel.org:/pub/scm/linux/kernel/git/dtor/input.git/

The main feature is psmouse resync patch which should make PS/2 mice
useable with cheap KVMs that reset mice when switching between boxes.
Also there is a fix for OOps in PID code, build for for powerpc and
HID tweaks to make new USB-based keyboards behave like older ADB ones.

Changelog:

	Input: i8042 - add Sony Vaio FSC-115b to MUX blacklist (Vojtech)
	Input: HID - add support for Cherry Cymotion keyboard (Vojtech)
	Input: HID - fix an oops in PID initialization code
	Input: psmouse - attempt to re-synchronize mouse every 5 seconds
	Input: HID - add more simulation usages
	Input: wacom - fix compile on PowerPC
	Input: HID - add support for fn key on Apple PowerBooks (Michael Hanselmann)

[git pull 2/7] HID: Add support for Cherry Cymotion keyboard

[Dmitry Torokhov]

[-- Attachment #1: cherry-cymotion-support.patch --]
[-- Type: text/plain, Size: 3866 bytes --]

From: Vojtech Pavlik <vojtech@suse.cz>

Input: HID - add support for Cherry Cymotion keyboard

The Cherry Cymotion is a special Linux keyboard made by Cherry, with
only one little problem: it doesn't work with Linux. This patch
(originally by hexten.net, cleaned up by me) makes it work including
all the special keys.
