Since v3.0 kernel, acer-wmi driver auto detects internal 3G device and
provides the threeg rfkill interface. So the sysfs interface of 3G is
no longer necessary now.

The 7b8aca65 patch added kernel information log to remind to user space
for the threeg sysfs interface will be removed in 2012, then b58b9ffc patch
updated the interface removing time to 2014.

I think the 3 years lead time is enough for user space application to use
rfkill instead of sysfs interface to control 3G device.

This patch removes code about threeg sysfs interface. And it also removes the
unused interface sysfs that exposes which ACPI-WMI method used by acer-wmi
driver on the machine. The information is already exposed by the acer-wmi
initial log.

Toshiba laptops that feature WMI events for hotkeys were left unsupported
by the toshiba_acpi driver, however, commit a88bc06e ("toshiba_acpi:
Avoid registering input device on WMI event laptops") added hardware
support for such laptops, but the hotkeys are not handled there.

This driver adds support for hotkey monitoring on certain Toshiba laptops
that manage the hotkeys via WMI events instead of the Toshiba
Configuration Interface (TCI).

The toshiba_acpi driver and this one can co-exist, as this only takes
care of hotkeys, while the proper takes care of hardware related stuff.

Currently the driver is under the EXPERIMENTAL flag, as the keymap
and the notify function are incomplete (due to lack of hardware to test).

The IRQF_NO_SUSPEND flag is used to identify the interrupts that should
be left enabled so as to allow them to work as expected during the
suspend-resume cycle, but doesn't guarantee that it will wake the system
from a suspended state, enable_irq_wake is recommended to be used for
the wakeup.

This patch removes the use of IRQF_NO_SUSPEND flags and uses newly
introduce PM wakeup APIs dev_pm_{set,clear}_wake_irq.

The driver currently uses the hotkey enabling value of 0x09 to enable
hotkey events, but windows uses a different value (0x01).

All Toshiba laptops accept the following "hotkey" parameters:
0x01 - Enable hotkey and system events.
0x03 - Enable system events only.
0x09 - Enable hotkey events only.
0x0b - Disable (hotkey and system) events.

This patch changes the default hotkey enabling value from 0x09 to 0x01,

Prior to the VRF change the oif was not set in the flow struct, so the
VRF support should really have only added the vrf_master_ifindex lookup.

The generic empty pci_iomap and pci_iounmap is used only if CONFIG_PCI

 "This is an assorted set I've been queuing up:

  Jeff Mahoney tracked down a tricky one where we ended up starting IO
  on the wrong mapping for special files in btrfs_evict_inode.  A few
  people reported this one on the list.

  Filipe found (and provided a test for) a difficult bug in reading
  compressed extents, and Josef fixed up some quota record keeping with
  snapshot deletion.  Chandan killed off an accounting bug during DIO
  that lead to WARN_ONs as we freed inodes"
