Jesse Barnes a3424216e4 ips: use interruptible waits in ips-monitor
This is what I intended to do since:
  1) the driver handles variable waits just fine, and
  2) interruptible waits aren't reported as load in the load avg.

Lee, Chun-Yi 70a9b9047a acer-wmi: does not poll device status when WMI event is available
Acer WMI hotkey event's result include current device status, just
need sync the status to killswitch after acer-wmi driver receive
hotkey event but not always poll device status. This is good for
performance.

But, if use EC raw mode, Acer BIOS will not emit wmi event and
leave EC to control device status. So, still startup polling job
when doesn't detect WMI event GUID or user choice to use ec_raw_mode.

Tested on Acer TravelMate 8572 notebook.

Lee, Chun-Yi 8215af0190 acer-wmi: does not set persistence state by rfkill_init_sw_state
Acer BIOS keeps devices state when system reboot, but reset to default
device states (Wlan on, Bluetooth off, wwan on) if system cold boot.
That means BIOS's initial state is not always real persistence.

So, removed rfkill_init_sw_state because it sets initial state to
persistence then replicate to other new killswitch when rfkill-input
enabled.
After removed it, acer-wmi set initial soft-block state after rfkill
register, and doesn't allow set_block until rfkill initial finished.

Actually, we can capture the real touchpad status by read 0xE4 EC address
on MSI netbook/notebook. So, add msi-laptop input device for send out
KEY_TOUCHPAD_ON or KEY_TOUCHPAD_OFF key when user pressed Fn+F3 touchpad
hotkey. It leave userland applications to know the real touchpad status.

Tested on MSI netbook U-100, U-115, U160(N051), U160DX, N014, N034
Tested on MSI notebook CR620

Corentin Chary b229ece991 asus-nb-wmi: Asus Notebooks WMI Driver
Introduce a new driver for Asus Notebooks shipped with
a WMI device instead of the old ACPI device. The WMI
device is almost the same as the one present in Eee PC,
but the event guid and the keymap are different.

The keymap comes from asus-laptop module.

On Asus notebooks, when you call the WMI device, you always
need a 64bit buffer, even if you only want to get the state
of a device (tested on a G73).

Corentin Chary 1d070f89a7 asus-wmi: try to guess the right DSTS methods
This is tricky, new WMI aware notebooks seems to use
0x53545344 while Eee PCs are using 0x53544344. But there
is no way to know if there is an Eee PC in that wild that is
using 0x53545344 or a notebook using 0x53544344. So the
driver try to guess the available DSTS method ... But most Eee PCs
never return 0xFFFFFFFE when a method is not available, they return
0 instead (and that's useless).

So, first, try 0x53544344 then 0x53545344. We will find
a better way when we got more data.

The maximum input buffer size is kept at 4 bytes as per struct
