Pull x86 platform driver updates from Matthew Garrett:
"Very little of excitement here - the most significant is a new driver
for detecting device freefall on Dells, other than that it's pretty
much entirely minor fixes for specific machines"
* 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86:
hp-wmi: Enable hotkeys on some systems
thinkpad_acpi: Add mappings for F9 - F12 hotkeys on X240 / T440 / T540
platform: x86: dell-smo8800: Dell Latitude freefall driver (ACPI SMO8800/SMO8810)
ideapad_laptop: Introduce the use of the managed version of kzalloc
platform/x86: Fix run-time dependencies of OLPC drivers
platform: x86: asus-wmi.c: Cleaning up uninitialized variables
ix86/mid/thermal: Introduce the use of the managed version of kzalloc
platform x86 Kconfig: Refer to the laptop list in the Compal driver help
Documentation: Add list of laptop models supported by the Compal driver
ideapad-laptop: Blacklist rfkill control on the Lenovo Yoga 2 11
asus-wmi: Set WAPF to 4 for Asus X550CA
alienware-wmi: For WMAX HDMI method, introduce a way to query HDMI cable status
alienware-wmi: Update WMAX brightness method limit to 15
pvpanic: Set high notifier priority
platform/x86: samsung-laptop: Add support for Samsung's NP7[34]0U3E models.
toshiba_acpi: Add alternative keymap support for Satellite M840
platform-drivers-x86: intel_pmic_gpio: Fix off-by-one valid offset range check
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.

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.

This patch moves data allocated using kzalloc to managed data allocated

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

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

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
overriding, and the Unload() operator. The acpidump utility from

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.

* 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.

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.

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.

scancodes whenever enabled/disabled, and another one
by pressing Fn-F9 (touchpad toggle) hotkey.

by exposing the _touchpad_ file in sysfs that simply
makes a call to a SCI register, imitating what
Toshiba provided software does on Windows.

Toshiba laptops equiped with an illuminated keyboard
can operate in two different modes: Auto and FN-Z.
The Auto mode turns on the led on keystrokes and
automatically turns it off after some (configurable)
time the last key was pressed.
The FN-Z mode is used to toggle the keyboard led on/off
by userspace.
This patch adds support to set the desired KBD mode and
timeout via sysfs, creates and registers toshiba::kbd_backlight
led device whenever the mode is set to FN-Z.
The acceptable values for mode are: 1 (Auto) and 2 (Fn-Z)
The time values range are: 1-60 seconds
