Disabling gpe might interfere with gpe detection/handling,
thus producing "interrupt not handled" errors.
Ironically, disabling of GPE from interrupt context is already
under spinlock, so only userspace needs to start using it.

Currently not always an EV_SYN event is reported to userland
after the EV_SW SW_LID event has been sent. This is easy to verify
by using “input-events” from input-utils and just closing and opening
the lid.

As of version 2.0, ACPI can return 64-bit integers. The current
acpi_evaluate_integer only supports 64-bit integers on 64-bit platforms.
Change the argument to take a pointer to an acpi_integer so we support
64-bit integers on all platforms.
lenb: replaced use of "acpi_integer" with "unsigned long long"

Use proc_create()/proc_create_data() to make sure that ->proc_fops and ->data
be setup before gluing PDE to main tree.
Add correct ->owner to proc_fops to fix reading/module unloading race.

get rid of input BIT* duplicate defines
use newly global defined macros for input layer. Also remove includes of
input.h from non-input sources only for BIT macro definiton. Define the
macro temporarily in local manner, all those local definitons will be
removed further in this patchset (to not break bisecting).
BIT macro will be globally defined (1<<x)

In addition to signalling button/lid events through /proc/acpi/event,
create separate input devices and report KEY_POWER, KEY_SLEEP and
SW_LID through input layer. Also remove unnecessary casts and variable
initializations, clean up formatting.
Sleep button may autorepeat but userspace will have to filter duplicate
sleep requests anyway (and discard unprocessed events right after
wakeup).
Unlike /proc/acpi/event interface input device corresponding to LID
switch reports true lid state instead of just a counter. SW_LID is
active when lid is closed.
The driver now depends on CONFIG_INPUT.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
