Pull remove-hotkey into release branch

driver/acpi/hotkey.c implement:
1. /proc/acpi/hotkey/event_config
(event based hotkey or event config interface):
a. add a event based hotkey(event) :
echo "0:bus::action:method:num:num" > event_config
b. delete a event based hotkey(event):
echo "1:::::num:num" > event_config
c. modify a event based hotkey(event):
echo "2:bus::action:method:num:num" > event_config
2. /proc/acpi/hotkey/poll_config
(polling based hotkey or event config interface):
a.add a polling based hotkey(event) :
echo "0:bus:method:action:method:num" > poll_config
this adding command will create a proc file
/proc/acpi/hotkey/method, which is used to get
result of polling.
b.delete a polling based hotkey(event):
echo "1:::::num" > event_config
c.modify a polling based hotkey(event):
echo "2:bus:method:action:method:num" > poll_config
3./proc/acpi/hotkey/action
(interface to call aml method associated with a
specific hotkey(event))
echo "event_num:event_type:event_argument" >
/proc/acpi/hotkey/action.
The result of the execution of this aml method is
attached to /proc/acpi/hotkey/poll_method, which is dynamically
created. Please use command "cat /proc/acpi/hotkey/polling_method"
to retrieve it.
Note: Use cmdline "acpi_generic_hotkey" to over-ride
platform-specific with generic driver.

What: ACPI hotkey driver (CONFIG_ACPI_HOTKEY)
When: 2.6.21
Why: hotkey.c was an attempt to consolidate multiple drivers that use
ACPI to implement hotkeys. However, hotkeys are not documented
in the ACPI specification, so the drivers used undocumented
vendor-specific hooks and turned out to be more different than
the same.
Further, the keys and the features supplied by each platform
are different, so there will always be a need for
platform-specific drivers.
So the new plan is to delete hotkey.c and instead, work on the
platform specific drivers to try to make them look the same
to the user when they supply the same features.
hotkey.c has always depended on CONFIG_EXPERIMENTAL
