Acer WMID_GUID1/2 method's return buffer was declared to 64-bits
on some Acer notebook, but WMI method only use 32-bits in return
buffer.
So, add this patch for allow 64-bits return buffer.

That will be better to check the existence of internal 3G device when
we set threeg capability and generate killswitch for threeg. It can
avoid userland access 3G rfkill but the machine doesn't have internal
3G device.

On an Acer Travelmate 5735Z-452G32Mnss the WLAN-enable/disable key
doesn't send 0x1 as acpi event key code, but 0x3. This patch also
makes the module ignore hotkey acpi events for functions that are
already handled without. This avoids warning message "keyboard:
can't emulate rawmode for keycode 240".

* The acerhdf driver isn't an ACPI driver, so it needs not include
  <acpi/acpi_drivers.h>. All it uses is ec_read() and ec_write(), for
  which <linux/acpi.h> is sufficient.
* I couldn't find any reason why <linux/fs.h> and <linux/sched.h> were
  included.

This should avoid unneeded rebuilds of the acerhdf driver.

This driver implements an Extra ACPI EC driver for products based on Intel
Oaktrail platform.

This driver does below things:
1. registers itself in the Linux backlight control in
   /sys/class/backlight/intel_oaktrail/

2. registers in the rfkill subsystem here: /sys/class/rfkill/rfkillX/
   for these components: wifi, bluetooth, wwan (3g), gps

The presense of a writeq() implementation on 32-bit x86 that splits the
64-bit write into two 32-bit writes turns out to break the mpt2sas driver
(and in general is risky for drivers as was discussed in
<http://lkml.kernel.org/r/adaab6c1h7c.fsf@cisco.com>).  To fix this,
revert 2c5643b1 ("x86: provide readq()/writeq() on 32-bit too") and
follow-on cleanups.

This unfortunately leads to pushing non-atomic definitions of readq() and
write() to various x86-only drivers that in the meantime started using the
definitions in the x86 version of <asm/io.h>.  However as discussed
exhaustively, this is actually the right thing to do, because the right
way to split a 64-bit transaction is hardware dependent and therefore
belongs in the hardware driver (eg mpt2sas needs a spinlock to make sure
no other accesses occur in between the two halves of the access).

Build tested on 32- and 64-bit x86 allmodconfig.
