Seth Forshee 39bbde0599 asus-wmi: Enable autorepeat for hotkey input device
The T101MT Home/Express Gate key autorepeats in hardware, but
sparse-keymap does not support hardware autorepeat. Enable the
input core's software autorepeat to emulate the hardware behavior.
Normal hotkeys are autoreleased, so the behavior of these keys
will not be affected.

Seth Forshee 6ae8b80737 eeepc-wmi: Add support for T101MT Home/Express Gate key
This key is different than other hotkeys, having seperate scan
codes for press, release, and hold, so it requires some special
filtering. Press and release events are passed on, and hold events
are ignored since sparse-keymap does not support hardware
autorepeat.

Note that "Home" in the context of this button doesn't mean the
same thing as the usual Home key, and it really isn't clear at
all what is meant by "Home". The manufacurer's description of the
button indicates that it should launch some sort of touch screen
settings interface on short press and apply a desktop rotation on
long press.

longer necessary.

We also plan to remove interface sysfs file that exposed which ACPI-WMI
interface that was used by acer-wmi driver. It will replaced by information
log when acer-wmi initial.

We keep it around for userspace compatibility reasons, schedule removal
in 2012.

Henrique de Moraes Holschuh a50245af78 thinkpad-acpi: handle HKEY 0x4010, 0x4011 events
Handle events 0x4010 and 0x4011 so that we do not pester users about them.

These events report when the thinkpad is docked/undocked to a native
hotplug dock (i.e. one that does not need ACPI handling, nor is represented
in the ACPI device tree).  Such docks are based on USB 2.0/3.0, and also
work as port replicators.

We really want a proper dock class to report these, or at least new input
EV_SW events.  Since it is not clear which one to use yet, keep reporting
them as vendor-specific ThinkPad events.

WARNING: As defined by the thinkpad-acpi sysfs ABI rules of engagement, the
vendor-specific events will be REMOVED as soon as generic events are made
available (duplicate events are a big problem), with an appropriate update
to the thinkpad-acpi sysfs/event ABI versioning.  Userspace is already
prepared to provide easy backwards compatibility for such changes when
convenient to the distro (see acpi-fakekey).

* Event 0x4010: docking to hotplug dock/port replicator
* Event 0x4011: undocking from hotplug dock/port replicator

Typical usecase would be to trigger display reconfiguration.

Reports mention T410, T510, and series 3 docks/port replicators.  Special
thanks to Robert de Rooy for his extensive report and analysis of the
situation.

Henrique de Moraes Holschuh 2d43f671c8 thinkpad-acpi: handle some new HKEY 0x60xx events
Handle some user interface events from the newer Lenovo models.  We are likely
to do something smart with these events in the future, for now, hide the ones
we are already certain about from the user and userspace both.

* Events 0x6000 and 0x6005 are key-related.  0x6005 is not properly identified
  yet.  Ignore these events, and do not report them.

* Event 0x6040 has not been properly identified yet, and we don't know if it
  is important (looks like it isn't, but still...).  Keep reporting it.

* Change the message the driver outputs on unknown 0x6xxx events, as all
  recent events are not related to thermal alarms.  Degrade log level from
  ALERT to WARNING.

Thanks to all users who reported these events or asked about them in a number
of mailing lists.  Your help is highly appreciated, even if I did took a lot of
time to act on them.  For that I apologise.

I will list those that identified the reasons for the events as "reported-by",
and I apologise in advance if I leave anyone out: it was not done on purpose, I
made the mistake of not properly tagging all event report emails separately,
and might have missed some.

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

reflect the wireless status. To fix this, only update rfkill states
when a wlan or bluetooth hotkey is pressed.

Melchior FRANZ 8ae68de15d support wlan hotkey on Acer Travelmate 5735Z
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".

Jean Delvare c4bae98c4f acerhdf: Clean up includes
* 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.

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

Roland Dreier dbee8a0aff x86: remove 32-bit versions of readq()/writeq()
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
EC version string is 6QHT28WW-1.09. The driver was requiring that both
of these have 'WW' in positions 6 and 7. I don't know what the
significance of having 'V1' there instead is, but removing the test
makes the driver load on my machine.

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.

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.

Corentin Chary e12e6d94db eeepc-wmi: asus generic asus-wmi.ko module
New Asus notebooks are using a WMI device similar to
the one used in Eee PCs. Since we don't want to load
eeepc-wmi module on Asus notebooks, and we want 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

Corentin Chary 5b799d4fb7 asus-wmi: move generic code to asus-wmi
New Asus notebooks are using a WMI device similar to
the one used in Eee PCs. Since we don't want to load
a module named eeepc-laptop on Asus Notebooks, start by
copying all the code to asus-wmi.c.

Anssi Hannula 6d97db590c hp-wmi: clear rfkill device pointers when appropriate
NULLify rfkill pointers during initialization. This prevents dereference
of invalid pointer in case the driver is rebound and some rfkill device
isn't detected anymore. Clear them also in hp_wmi_rfkill_setup failure
path so that an rfkill initialization failure doesn't need to be fatal
for the whole driver.

Anssi Hannula c3021ea1be hp-wmi: allow setting input and output buffer sizes separately
Split buffersize parameter of hp_wmi_perform_query to insize and
outsize. Existing callers are changed to use the same value for insize
and outsize to avoid any regressions, with the exception of
hp_wmi_set_block where the output buffer is unused and therefore outsize
is set to 0 (this change is not seen by BIOS code).

The maximum input buffer size is kept at 4 bytes as per struct
bios_args. Some commands exist that take longer buffers, but they
haven't been implemented. The data portion of bios_args can be trivially
made dynamically allocated later when such larger buffers become needed.

There is not much use for these events in userspace and handling the
