eeepc-laptop init
I got the following oops while changing the backlight brightness during
startup. When it happens, it prevents use of the hotkeys, Fn-Fx, and the
lid button.
It's a clear use-before-init, as I verified by testing with an
appropriately-placed "else printk".

To be prepared for /proc/acpi/event removal we export events
also through generic netlink interface.

The Eee implements rfkill by logically unplugging the wireless card from the
PCI bus. Despite sending ACPI notifications, this does not appear to be
implemented using standard ACPI hotplug - nor does the firmware provide the
_OSC method required to support native PCIe hotplug. The only sensible choice
appears to be to handle the hotplugging directly in the eeepc-laptop driver.
Tested successfully on a 700, 900 and 901.

Newer Eees have extra hotkeys above the function keys. This patch adds support
for sending them through the input layer.

eeepc_backlight_exit() was doing rfkill and input stuff, which
is a nonsense. This patch add two specific exit functions, one
for input and one for rfkill.

Although rfkill support for the EEE bluetooth device has been added to
2.6.28-rc the appropriate ACPI accessor definitions were not added, so
the support was non functional. The patch below adds the get and set
accessors and has been verified to work on an EEE 901.

Move x86 platform specific drivers from drivers/misc/
to a new home under drivers/platform/x86/.
The community has been maintaining x86 vendor-specific
platform specific drivers under /drivers/misc/ for a few years.
The oldest ones started life under drivers/acpi.
They moved out of drivers/acpi/ because they don't actually
implement the ACPI specification, but either simply
use ACPI, or implement vendor-specific ACPI extensions.
In the future we anticipate...
drivers/misc/ will go away.
other architectures will create drivers/platform/<arch>
