f82bdd0d77 hp-wmi: Enable hotkeys on some systems
This is a third attempt to enable these buttons. The new variable being
commit 997daa1bd9 (i.e. hp-wmi: detect
"2009 BIOS or later"). Older systems that do not have the 2009 BIOS query
method respond with a dummy value, in this case 4. Using that, we can
target a fairly narrow group of systems. i.e. old enough to not have
HPWMI_FEATURE_QUERY 0xd, but new enough to have HPWMI_BIOS_QUERY 0x9.
This group may be further limited if some systems respond with something
other than 4 to non-existant feature queries.

8b9dd4fab2 thinkpad_acpi: Add mappings for F9 - F12 hotkeys on X240 / T440 / T540
The T440s user guide says that when Fn-lock is not active, the *40s' F9 - F12
keys should be mapped to: control-panel, search, show-all-windows and Computer.

These keys generate the sofar unused 28 - 31 hotkey scancodes.

For the first 2 this nicely matches the icons on the keys, for the latter 2
the icons are somewhat creative, which is why I ended up looking them up in
the user manual.

b3facd7ba8 ideapad_laptop: Introduce the use of the managed version of kzalloc
This patch moves data allocated using kzalloc to managed data allocated
using devm_kzalloc and cleans now unnecessary kfrees in probe and remove

required.  Also, linux/device.h is added to make sure the devm_*()
routine declarations are unambiguously available.

The following Coccinelle semantic patch was used for making the change:

7939831eac pvpanic: Set high notifier priority
We've observed the missing pvpanic call at panic, and it turned out
that this was blocked by the broken notifier of drm_fb_helper, where
scheduling may be called during switching to the fb console.
It's fairly difficult to fix the drm_fb problem and a quick fix isn't
foreseen, a simpler solution for the missing pvpanic call would be
just to call this earlier.

In order to assure that, this patch sets a higher priority to pvpanic
notifier_block.  Once when the issue of drm_fb is resolved, we can
remove this priority again.

Merge tag 'pm+acpi-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm into next

Pull ACPI and power management updates from Rafael Wysocki:
 "ACPICA is the leader this time (63 commits), followed by cpufreq (28
  commits), devfreq (15 commits), system suspend/hibernation (12
  commits), ACPI video and ACPI device enumeration (10 commits each).

  We have no major new features this time, but there are a few
  significant changes of how things work.  The most visible one will
  probably be that we are now going to create platform devices rather
  than PNP devices by default for ACPI device objects with _HID.  That
  was long overdue and will be really necessary to be able to use the
  same drivers for the same hardware blocks on ACPI and DT-based systems
  going forward.  We're not expecting fallout from this one (as usual),
  but it's something to watch nevertheless.

  The second change having a chance to be visible is that ACPI video
  will now default to using native backlight rather than the ACPI
  backlight interface which should generally help systems with broken
  Win8 BIOSes.  We're hoping that all problems with the native backlight
  handling that we had previously have been addressed and we are in a
  good enough shape to flip the default, but this change should be easy
  enough to revert if need be.

  In addition to that, the system suspend core has a new mechanism to
  allow runtime-suspended devices to stay suspended throughout system
  suspend/resume transitions if some extra conditions are met
  (generally, they are related to coordination within device hierarchy).
  However, enabling this feature requires cooperation from the bus type
  layer and for now it has only been implemented for the ACPI PM domain
  (used by ACPI-enumerated platform devices mostly today).

  Also, the acpidump utility that was previously shipped as a separate
  tool will now be provided by the upstream ACPICA along with the rest
  of ACPICA code, which will allow it to be more up to date and better
  supported, and we have one new cpuidle driver (ARM clps711x).

  The rest is improvements related to certain specific use cases,
  cleanups and fixes all over the place.

  Specifics:

   - ACPICA update to upstream version 20140424.  That includes a number
     of fixes and improvements related to things like GPE handling,
     table loading, headers, memory mapping and unmapping, DSDT/SSDT

     machines and using native backlight by default.

   - ACPI device enumeration changes to create platform devices rather
     than PNP devices for ACPI device objects with _HID by default.  PNP
     devices will still be created for the ACPI device object with
     device IDs corresponding to real PNP devices, so that change should
     not break things left and right, and we're expecting to see more
     and more ACPI-enumerated platform devices in the future.  From
     Zhang Rui and Rafael J Wysocki.

5142c33ed8 Staging driver patches for 3.16-rc1
Here is the big staging driver pull request for 3.16-rc1.
 
 Lots of stuff here, tons of cleanup patches, a few new drivers, and some
 removed as well, but I think we are still adding a few thousand more
 lines than we remove, due to the new drivers being bigger than the ones
 deleted.
 
 One notible bit of work did stand out, Jes Sorensen has gone on a tear,
 fixing up a wireless driver to be "more sane" than it originally was
 from the vendor, with over 500 patches merged here.  Good stuff, and a
 number of users laptops are better off for it.
 
 All of this has been in linux-next for a while.

By reading the touchscreen configuration from the settings that the

The matrix size is not used for anything, and results in some rather
confusing code to re-read it because it may change when configuration

d13374154e acer-wmi: Switch to acpi_video_unregister_backlight
Switch from acpi_video_unregister(), to acpi_video_unregister_backlight(),
so that the hotkeys handler registered by acpi-video stays in place.

Since there are no mappings for the atkbd raw codes for the brightness
keys used by newer Acer models in /lib/udev/hwdb.d/60-keyboard.hwdb, and
since we map the wmi events with a code of KE_IGNORE, we rely on acpi-video
to do the hotkey handling for us.

For laptops such as the Acer Aspire 5750 which uses intel gfx this works
despite us calling acpi_video_unregister() because the following happens:

 1) acpi-video module gets loaded (as it is a dependency of acer-wmi and i915)
 2) acpi-video does NOT call acpi_video_register()
 3) acer-wmi loads (assume it loads before i915), calls
    acpi_video_dmi_promote_vendor(); which sets
    ACPI_VIDEO_BACKLIGHT_DMI_VENDOR
 4) calls acpi_video_unregister -> not registered, nop
 5) i915 loads, calls acpi_video_register
 6) acpi_video_register registers the acpi_notifier for the hotkeys,
    does NOT register a backlight device because of
    ACPI_VIDEO_BACKLIGHT_DMI_VENDOR

But on the Acer Aspire 5750G, which uses nvidia graphics the following happens:
 1) acpi-video module gets loaded (as it is a dependency of acer-wmi)
 2) acpi-video calls acpi_video_register()
 3) acpi_video_register registers the acpi_notifier for the hotkeys,
    and a backlight device
 4) acer-wmi loads, calls acpi_video_dmi_promote_vendor()
 5) calls acpi_video_unregister, this unregisters BOTH the acpi_notifier for
    the hotkeys AND the backlight device

And we end up without any handler for the brightness hotkeys. This patch fixes
this by switching over to acpi_video_unregister_backlight() which keeps the
hotkey handler in place.

fb5e4c3ee1 Input: atmel_mxt_ts - improve T19 GPIO keys handling
* The mapping of the GPIO numbers into the T19 status byte varies between
   different maXTouch chips. Some have up to 7 GPIOs. Allowing a keycode array
   of up to 8 items is simpler and more generic. So replace #define with
   configurable number of keys which also allows the removal of is_tp.
 * Rename platform data parameters to include "t19" to prevent confusion with
   T15 key array.
 * Probe aborts early on when pdata is NULL, so no need to check.
 * Move "int i" to beginning of function (mixed declarations and code)
 * Use API calls rather than __set_bit()
 * Remove unused dev variable.

2cefdb1f0a Input: atmel_mxt_ts - remove unnecessary platform data
It is not necessary to download these values to the maXTouch chip on every
probe, since they are stored in NVRAM. It makes life difficult when tuning
the device to keep them in sync with the config array/file, and requires a
new kernel build for minor tweaks.

These parameters only represent a tiny subset of the available
configuration options, tracking all of these options in platform data would
be a endless task. In addition, different versions of maXTouch chips may
have these values in different places or may not even have them at all.

Having these values also makes life more complex for device tree and other
platforms where having to define a static configuration isn't helpful.

a4d44ba126 x86, acpi: LLVMLinux: Remove nested functions from Thinkpad ACPI
The only real change is passing in event_mask to the formerly nested functions.
Otherwise it's just moving around function and macro code.

This is the only place in the Linux kernel where nested functions are still in
use. Nested functions aren't part of the C standards, and complicate the
generated code. Although the Linux Kernel has never set out to be entirely C
standard compliant, it is increasingly compliant to the standard which is
supported by other compilers such as Clang. The LLVMLinux project is working on
being able to compile the Linux kernel with Clang. The use of nested functions
blocks this effort.
