033d9959ed Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue changes from Tejun Heo:
 "This is workqueue updates for v3.7-rc1.  A lot of activities this
  round including considerable API and behavior cleanups.

   * delayed_work combines a timer and a work item.  The handling of the
     timer part has always been a bit clunky leading to confusing
     cancelation API with weird corner-case behaviors.  delayed_work is
     updated to use new IRQ safe timer and cancelation now works as
     expected.

   * Another deficiency of delayed_work was lack of the counterpart of
     mod_timer() which led to cancel+queue combinations or open-coded
     timer+work usages.  mod_delayed_work[_on]() are added.

     These two delayed_work changes make delayed_work provide interface
     and behave like timer which is executed with process context.

   * A work item could be executed concurrently on multiple CPUs, which
     is rather unintuitive and made flush_work() behavior confusing and
     half-broken under certain circumstances.  This problem doesn't
     exist for non-reentrant workqueues.  While non-reentrancy check
     isn't free, the overhead is incurred only when a work item bounces
     across different CPUs and even in simulated pathological scenario
     the overhead isn't too high.

     All workqueues are made non-reentrant.  This removes the
     distinction between flush_[delayed_]work() and
     flush_[delayed_]_work_sync().  The former is now as strong as the
     latter and the specified work item is guaranteed to have finished
     execution of any previous queueing on return.

   * In addition to the various bug fixes, Lai redid and simplified CPU
     hotplug handling significantly.

   * Joonsoo introduced system_highpri_wq and used it during CPU
     hotplug.

  There are two merge commits - one to pull in IRQ safe timer from
  tip/timers/core and the other to pull in CPU hotplug fixes from
  wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."

Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.

Tejun pointed out a few of them, I fixed a couple more.

* 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits)

concerning GPU switching. Special thanks to Seth Forshee who helped

a50bd128f2 asus-wmi: record wlan status while controlled by userapp
If the user bit is set, that mean BIOS can't set and record the wlan
status, it will report the value read from id ASUS_WMI_DEVID_WLAN_LED
(0x00010012) while we query the wlan status by id ASUS_WMI_DEVID_WLAN
(0x00010011) through WMI.
So, we have to record wlan status in id ASUS_WMI_DEVID_WLAN_LED
(0x00010012) while setting the wlan status through WMI.
This is also the behavior that windows app will do.

Quote from ASUS application engineer
===
When you call WMIMethod(DSTS, 0x00010011) to get WLAN status, it may return

(1) 0x00050001 (On)
(2) 0x00050000 (Off)
(3) 0x00030001 (On)
(4) 0x00030000 (Off)
(5) 0x00000002 (Unknown)

(1), (2) means that the model has hardware GPIO for WLAN, you can call
WMIMethod(DEVS, 0x00010011, 1 or 0) to turn WLAN on/off.
(3), (4) means that the model doesn’t have hardware GPIO, you need to use
API or driver library to turn WLAN on/off, and call
WMIMethod(DEVS, 0x00010012, 1 or 0) to set WLAN LED status.
After you set WLAN LED status, you can see the WLAN status is changed with
WMIMethod(DSTS, 0x00010011). Because the status is recorded lastly
(ex: Windows), you can use it for synchronization.
(5) means that the model doesn’t have WLAN device.

WLAN is the ONLY special case with upper rule.

For other device, like Bluetooth, you just need use
WMIMethod(DSTS, 0x00010013) to get, and WMIMethod(DEVS, 0x00010013, 1 or 0)
to set.

41f63c5359 workqueue: use mod_delayed_work() instead of cancel + queue
Convert delayed_work users doing cancel_delayed_work() followed by
queue_delayed_work() to mod_delayed_work().

Most conversions are straight-forward.  Ones worth mentioning are,

* drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always
  use mod_delayed_work() and cancel loop in
  edac_mc_reset_delay_period() is dropped.

* drivers/platform/x86/thinkpad_acpi.c: No need to remember whether
  watchdog is active or not.  @fan_watchdog_active and related code
  dropped.

* drivers/power/charger-manager.c: Seemingly a lot of
  delayed_work_pending() abuse going on here.
  [delayed_]work_pending() are unsynchronized and racy when used like
  this.  I converted one instance in fullbatt_handler().  Please
  conver the rest so that it invokes workqueue APIs for the intended
  target state rather than trying to game work item pending state
  transitions.  e.g. if timer should be modified - call
  mod_delayed_work(), canceled - call cancel_delayed_work[_sync]().

* drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling()
  simplified.  Note that round_jiffies() calls in this function are
  meaningless.  round_jiffies() work on absolute jiffies not delta
  delay used by delayed_work.

v2: Tomi pointed out that __cancel_delayed_work() users can't be
    safely converted to mod_delayed_work().  They could be calling it
    from irq context and if that happens while delayed_work_timer_fn()
    is running, it could deadlock.  __cancel_delayed_work() users are
    dropped.

3567a4e2c5 platform / x86 / PM: Fix unused function warnings for CONFIG_PM_SLEEP
According to compiler warnings, quite some suspend/resume functions
in platform x86 drivers are not used for CONFIG_PM_SLEEP unset, so
add #ifdefs to prevent them from being built in that case.

6cca83d498 Platform: OLPC: move debugfs support from x86 EC driver
There's nothing about the debugfs interface for the EC driver that is
architecture-specific, so move it into the arch-independent driver.

The code is mostly unchanged with the exception of renamed variables, coding
style changes, and API updates.

This uses the new EC driver framework in drivers/platform/olpc.  The
XO-1 and XO-1.5-specific code is still in arch/x86, but the generic stuff
(including a new workqueue; no more running EC commands with IRQs disabled!)

d278b7a2f9 Platform: OLPC: add a suspended flag to the EC driver
A problem we've noticed on XO-1.75 is when we suspend in the middle of
an EC command.  Don't allow that.

In the process, create a private object for the generic EC driver to use;
we have a framework for passing around a struct, use that rather than a
proliferation of global variables.

ac2504151f Platform: OLPC: turn EC driver into a platform_driver
The 1.75-based OLPC EC driver already does this; let's do it for all EC
drivers.  This gives us nice suspend/resume hooks, amongst other things.

We want to run the EC's suspend hooks later than other drivers (which may
be setting wakeup masks or be running EC commands).  We also want to run
the EC's resume hooks earlier than other drivers (which may want to run EC
commands).

3d26c20bae Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call it
This provides a new API allows different OLPC architectures to override the
EC driver.  x86 and ARM OLPC machines use completely different EC backends.

The olpc_ec_cmd is synchronous, and waits for the workqueue to send the
command to the EC.  Multiple callers can run olpc_ec_cmd() at once, and
they will by serialized and sleep while only one executes on the EC at a time.

We don't provide an unregister function, as that doesn't make sense within
the context of OLPC machines - there's only ever 1 EC, it's critical to
functionality, and it certainly not hotpluggable.

d2044c5a3a asus-nb-wmi: add wapf quirk for ASUS machines
The BIOS of these machines will try to enable/disable wifi/bt in
their own sqeuence. It won't read the enable/disable parameter
in WMI command, but just iterates the wifi/bt's status described below
1st. enable wifi, enable bt
2nd. disable wifi, enable bt
3rd. enable wifi, disable bt
4th. disable wifi, disable bt
That will totally mess up the rfkill status, since we will try to read
wifi and bt's status and reset it again while booting up.

To avoid this, these machines should set the wapf value to 4,
that will let software totally control the wifi/bt's status and
BIOS will do nothing instead of sending out the 0x88(KEY_RFKILL) event
instead of 0x5e(wifi enable), 0x5f(wifi diable), 0x7d(bt enable), and
0x7e(bt disable) through WMI.

With this patch[1], it will handle the KEY_RFKILL event correctly and
will block/unblock wifi and bt together.

c0b91b6d52 asus-wmi: enable resume on lid open
According to the ASUS WMI spec., to enable resume on lid open should
use the device ID(0x00120032), but it doesn't work indeed.

After discussing with ASUS' BIOS engineer, they say wake on lid open
doesn't have a uniq device ID(0x00120032) in the BIOS. It shares the same

272c77d556 asus-wmi: control backlight power through WMI, not ACPI
BugLink: https://bugs.launchpad.net/bugs/1000146

Some h/w that can adjust screen brightness through ACPI functions, but
can't turn on/off the backlight power correctly. So, we list those h/w in
quirks and try to turn on/off the backlight power through WMI.

 "Re-write of the turbostat tool.
     lower overhead was necessary for measuring very large system when
     they are very idle.

  IVB support in intel_idle
     It's what I run on my IVB, others should be able to also:-)

  ACPICA core update
     We have found some bugs due to divergence between Linux and the
     upstream ACPICA base.  Most of these patches are to reduce that
     divergence to reduce the risk of future bugs.

  Some cpuidle updates, mostly for non-Intel

050eff39af acer-wmi: add 3 laptops to video backlight vendor mode quirk table
Acer Extensa 5235, TravelMate 5760 and Aspire 5750 laptop have broken _BCM
implemenation, the AML code wrote value to EC register but firmware didn't
change brighenss.

Fortunately, the brightness control works on those machines with vendor mode.
So, add this machine to video backlight vendor mode quirk table.

bc7ab495c7 xo1-rfkill: only act when blocked state is changed
The XO-1 rfkill driver should only send EC commands when changing
between blocked/unblocked state.

The rfkill switch is asked to be unblocked on every resume (even when
the card was never blocked before) and sending a EC_WLAN_LEAVE_RESET
command here upsets the resume sequence of the libertas driver. Adding
the check to avoid the spurious EC_WLAN_LEAVE_RESET fixes the wifi resume
behaviour.

The rfkill state is maintained by the hardware over suspend/resume
so no extra consideration is needed here.

351963bb58 acerhdf: lowered default temp fanon/fanoff values
Due to new supported hardware, of which the actual temperature limits of
processor, harddisk and other components are unknown, it feels safer with
lower fanon / fanoff settings.

It won't change much for most people, already using acerhdf, as they use
their own fanon/fanoff variable settings when loading the module.

Furthermore seems like kernel and userspace tools have been improved to
work more efficient and netbooks don't get so hot anymore.

c264c651fd Disable MCP limit exceeded messages from Intel IPS driver
On a system on the thermal limit these are quite noisy and flood the logs.
Better would be a counter anyways. But given that we don't even have
anything for normal throttling this doesn't seem to be urgent either.

There have some acer laptop have broken _BCM implemenation, the AML

Fortunately, the brightness control works on those machines with
vendor mode. So, add quirk table for video backlight vendor mode
and unregister acpi video interface on those machines.

41603e9783 drivers/platform/x86/amilo-rfkill.c::amilo_rfkill_probe() avoid NULL deref
In drivers/platform/x86/amilo-rfkill.c::amilo_rfkill_probe() the call
to dmi_first_match() may fail and return NULL. If it does return NULL,
then we'll be dereferencing a NULL pointer in the rfkill_alloc() call
where we do 'system_id->driver_data' --> KABOOM!

Avoid that problem by testing for a NULL return value from
dmi_first_match() and bailing out if it fails.

I was a bit uncertain about what to return in the failure case. In the
end I settled for -ENXIO as the most logical error to return.

6e0044bedc asus-wmi: store backlight power status for AIO machine
Due to some implementation reasons, ASUS ET2012 All-in-One machines
can't report the correct backlight power status, it will always return
1. To track the backlight power status correctly, we have to store the
status by ourselves.

BTW, by the BIOS design, the backlight power will be turn on/off
sequently, no matter what the value of the parameter will be.
More over, the brightness adjustment command will turn on the backlight
power. Those behaviors will make us fail to track the backlight power
status.
For example, While we are trying to turn on the backlight power,
we will send out the brightness adjustment command and then trying to
figure out if we have to turn on the backlight power, then send out
the command. But, the real case is that, the backlight power turns on
while sending the brightness adjustment command, and then we send out
the command to turn on the backlight power, it actually will turn off
the backlight power and the backlight power status we recorded becomes
wrong. So, we have to seperate these two commands by a if statement.

c87992d1fa asus-wmi: add scalar board brightness adj. support
Some ASUS ET2012E/I All-in-One machines that use a scalar board
to control the brightness, and they only accept brightness up and down
command. So, I introduced a get_scalar_command() function to pass the
command to the scalar board through WMI.

Besides, we have to store the brightness value locally, for we need the
old value to know the brightness value is increasing or decreasing.

BTW, since there is no way to retrieve the actual brightness(it would be
a fixed value), and the max brightness value would be fixed to 1, so we
have to keep passing the brightness up/down command when we reached the
max brightness value or 0.

29cd293f9f toshiba_acpi: Support alternate hotkey interfaces
There are two types of problems that prevent hotkeys from working
on many of the machines supported by toshiba_acpi. The first of
these is the lack of a functioning SCI for hotkey events. For these
machines it is possible to filter the Fn keypresses from the
keyboard and generate a notification by executing the ACPI NTFY
method.

The second problem is a lack of support for HCI_SYSTEM_EVENT, which
is used for reading the hotkey scancodes. On these machines the
scancodes can be read by executing the ACPI NTFY method.

This patch fixes both problems by installing an i8042 filter when
the NTFY method is present to generate notifications and by
detecting which of INFO or HCI_SYSTEM_EVENT is supported for
reading scancodes. If neither method of reading scancodes is
supported, the hotkey input device is not registered.

In the 2.6.36 kernel we did not have the MSIC driver. Changed
all ipc_scu_reads/writes to use the MSIC driver and defines.
Added a fix from the 2.6.36 kernel where the SCU FW could send
a power button interrupt to the IA32 FW and the kernel was not
running yet. This resulted in the interrupt not getting cleared
and the power button was ignored. this fix just clears the
interrupt on start-up.

774b06780b asus-laptop: control how BLED and WLED should be exposed
Let the user tells if BLED and WLED should be exposed as led or
rfkill (the old sysfs are still here, but this adds a standard
interface to control the device).

For example on my A6JC, with WAPF=1, I would do:

$ modprobe asus-laptop wled_type=led bluetooth_type=rfkill

There is still no known way to automatically guess what BLED
and WLED methods will control, it's why user information is needed.

A userspace database could do that automatically, and maybe some DMI
matching in the driver.

747a562f34 to fix scancodes returned by sony-laptop driver
Fix scancodes returned by driver to match scancodes used to remap keys.

(Before the patch FN/E returned scancode 0x1B, but to remap scancode
0x14 had to be used).

The scancodes returned by the sony-laptop driver for function keys did not
match the scancodes used to remap keys.  Also, since the scancode was sent
to the input subsystem after the mapped keysym the /lib/udev/keymap
utility was confused about which scancode to report for which keysym.

This patch fixes the driver so the correct scancode is shown for each
key.  It also adds to the documentation a description of where to find
the scancodes.

6fe6ae56a7 sony-laptop: Enable keyboard backlight by default
When the keyboard backlight support was originally added, the commit said
to default it to on with a 10 second timeout.  That actually wasn't the
case, as the default value is commented out for the kbd_backlight parameter.
Because it is a static variable, it gets set to 0 by default without some
other form of initialization.

However, it seems the function to set the value wasn't actually called
immediately, so whatever state the keyboard was in initially would remain.
Then commit df410d5224 was introduced during the 2.6.39 timeframe to
immediately set whatever value was present (as well as attempt to
restore/reset the state on module removal or resume).  That seems to have
now forced the light off immediately when the module is loaded unless
the option kbd_backlight=1 is specified.

Let's enable it by default again (for the first time).  This should solve

on error.  Then it could bypass the sanity check (num_sifr > 255).
The subsequent call to kzalloc() would allocate a small buffer, leading
to a memory corruption.

461e74377c acer-wmi: No wifi rfkill on Lenovo machines
We have several reports which says acer-wmi is loaded on ideapads
and register rfkill for wifi which can not be unblocked.

Since ideapad-laptop also register rfkill for wifi and it works
reliably, it will be fine acer-wmi is not going to register rfkill
for wifi once VPC2004 is found.

Also put IBM0068/LEN0068 in the list. Though thinkpad_acpi has no
wifi rfkill capability, there are reports which says acer-wmi also
block wireless on Thinkpad E520/E420.

2d24c49080 Fujitsu tablet extras driver
This patch adds support for some of the devices within a wide variety
of Fujitsu Tablet Computers, both convertibles and slates. Primarily
it allows for the automatic detection of the tablet/notebook mode for
convertible tablet pc's, and orientation for docked slates. It also
adds support for the application panel buttons usually found next to
the tablet screen, and docking station detection for slates.

c215ab9a75 x86: Add amilo-rfkill driver for some Fujitsu-Siemens Amilo laptops
An rfkill driver based on the fsaa1655g and fsam7440 drivers for
Fujitsu-Siemens Amilo A1655 and M7440 models found at:

http://sourceforge.net/projects/fsaa1655g/
http://sourceforge.net/projects/fsam7440/

This adds DMI matching, replaces the procfs files with rfkill devices,
and uses the proper functions to write to the i8042 safely.

8bee7cea6c x86/mid/powerbtn: Use MSIC read/write instead of ipc_scu
In the 2.6.36 kernel we did not have the MSIC driver.  Changed
all ipc_scu_reads/writes to use the MSIC driver and defines.
Added a fix from the 2.6.36 kernel where the SCU FW could send a
power button interrupt to the IA32 FW and the kernel was not
running yet.  This resulted in the interrupt not getting cleared
and the power button was ignored.  this fix just clears the
interrupt on start-up.

797a796a13 asm-generic: architecture independent readq/writeq for 32bit environment
This provides unified readq()/writeq() helper functions for 32-bit
drivers.

For some cases, readq/writeq without atomicity is harmful, and order of
io access has to be specified explicitly.  So in this patch, new two
header files which contain non-atomic readq/writeq are added.

 - <asm-generic/io-64-nonatomic-lo-hi.h> provides non-atomic readq/
   writeq with the order of lower address -> higher address

 - <asm-generic/io-64-nonatomic-hi-lo.h> provides non-atomic readq/
   writeq with reversed order

This allows us to remove some readq()s that were added drivers when the
default non-atomic ones were removed in commit dbee8a0aff ("x86:
remove 32-bit versions of readq()/writeq()")

The drivers which need readq/writeq but can do with the non-atomic ones
must add the line:

  #include <asm-generic/io-64-nonatomic-lo-hi.h> /* or hi-lo.h */

But this will be nop in 64-bit environments, and no other #ifdefs are
required.  So I believe that this patch can solve the problem of
 1. driver-specific readq/writeq
 2. atomicity and order of io access

This patch is tested with building allyesconfig and allmodconfig as
ARCH=x86 and ARCH=i386 on top of tip/master.

8a32c441c1 freezer: implement and use kthread_freezable_should_stop()
Writeback and thinkpad_acpi have been using thaw_process() to prevent
deadlock between the freezer and kthread_stop(); unfortunately, this
is inherently racy - nothing prevents freezing from happening between
thaw_process() and kthread_stop().

This patch implements kthread_freezable_should_stop() which enters
refrigerator if necessary but is guaranteed to return if
kthread_stop() is invoked.  Both thaw_process() users are converted to
use the new function.

Note that this deadlock condition exists for many of freezable
kthreads.  They need to be converted to use the new should_stop or
freezable workqueue.

Tested with synthetic test case.
