acer-wmi is indiscriminately using the device state from hotkey
events to update the various rfkill states. On the Aspire 1830 this
can result in a soft block on the wlan when the touchpad hotkey is
pressed, as it is reporting a non-zero device state that does not
reflect the wireless status. To fix this, only update rfkill states
when a wlan or bluetooth hotkey is pressed.

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 2c5643b1c5 ("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.

My X201s BIOS version string is 6QET46V1 (1.16 ). The

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.

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.

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

of a device (tested on a G73).

This is tricky, new WMI aware notebooks seems to use

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.

New Asus notebooks are using a WMI device similar to

keep the eeepc-wmi module for backward compatibility,
this patch introduce a new module, named asus-wmi, that
will be used by eeepc-wmi and the new Asus Notebook WMI
Driver.
eeepc-wmi's input device strings (device name and phys)
are kept, but rfkill and led names are changed (s/eeepc/asus/).
This should not break anything since rfkill are used by type or

\AMW0.WMBC, which is the main method that we use,
is not reentrant. When wireless hotpluging is enabled,
toggling the status of the wireless device using WMBC will
trigger a notification and the notification handler need to
call WMBC again to get the new status of the device, this
will trigger the following error:
ACPI Error (dswload-0802): [_T_0] Namespace lookup failure, AE_ALREADY_EXISTS
ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20100428/psloop-231)
ACPI Error (psparse-0537): Method parse/execution failed [\AMW0.WMBC] (Node f7023b88), AE_ALREADY_EXISTS
ACPI: Marking method WMBC as Serialized because of AE_ALREADY_EXISTS error
Since there is currently no way to tell the acpi subsystem to mark
a method as serialized, we do it in eeepc-wmi.
Of course, we could let the first call fail, and then it would work,
but it doesn't seems really clean, and it will make the first
WMBC call return a random value.

Implement wireless like hotplug handling (code stolen from eeepc-laptop).
Reminder: on some models rfkill is implemented 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 platform driver.
