This adds some sysfs entries to provide userspace control of the
four-element LED "lightbar" on the Chromebook Pixel. This only instantiates
the lightbar controls if the device actually exists.
To prevent DoS attacks, this interface is limited to 20 accesses/second,
although that rate can be adjusted by a privileged user.
On Chromebooks without a lightbar, this should have no effect. On the
Chromebook Pixel, you should be able to do things like this:
$ cd /sys/devices/virtual/chromeos/cros_ec/lightbar
$ echo 0x80 > brightness
$ echo 255 > brightness
$
$ cat sequence
S0
$ echo konami > sequence
$ cat sequence
KONAMI
$
$ cat sequence
S0
And
$ cd /sys/devices/virtual/chromeos/cros_ec/lightbar
$ echo stop > sequence
$ echo "4 255 255 255" > led_rgb
$ echo "0 255 0 0 1 0 255 0 2 0 0 255 3 255 255 0" > led_rgb
$ echo run > sequence
Test the DoS prevention with this:
$ cd /sys/devices/virtual/chromeos/cros_ec/lightbar
$ echo 500 > interval_msec
$ time (cat version version version version version version version)

This adds the first few sysfs attributes for the Chrome OS EC. These
controls are made available under /sys/devices/virtual/chromeos/cros_ec
flashinfo - display current flash info
reboot - tell the EC to reboot in various ways
version - information about the EC software and hardware
Future changes will build on this to add additional controls.

Chromebooks have an Embedded Controller (EC) that is used to
implement various functions such as keyboard, power and battery.
The AP can communicate with the EC through different bus types
such as I2C, SPI or LPC.
The cros_ec mfd driver is then composed of a core driver that
register the sub-devices as mfd cells and provide a high level
communication interface that is used by the rest of the kernel
and bus specific interfaces modules.
Each connection method then has its own driver, which register
with the EC driver interface-agnostic interface.
Currently, there are drivers to communicate with the EC over
I2C and SPI and this driver adds support for LPC.

Intel's Quark X1000 SoC contains a set of registers called
Isolated Memory Regions. IMRs are accessed over the IOSF mailbox
interface. IMRs are areas carved out of memory that define
read/write access rights to the various system agents within the
Quark system. For a given agent in the system it is possible to
specify if that agent may read or write an area of memory
defined by an IMR with a granularity of 1 KiB.
Quark_SecureBootPRM_330234_001.pdf section 4.5 details the
concept of IMRs quark-x1000-datasheet.pdf section 12.7.4 details
the implementation of IMRs in silicon.
eSRAM flush, CPU Snoop write-only, CPU SMM Mode, CPU non-SMM
mode, RMU and PCIe Virtual Channels (VC0 and VC1) can have
individual read/write access masks applied to them for a given
memory region in Quark X1000. This enables IMRs to treat each
memory transaction type listed above on an individual basis and
to filter appropriately based on the IMR access mask for the
memory region. Quark supports eight IMRs.
Since all of the DMA capable SoC components in the X1000 are
mapped to VC0 it is possible to define sections of memory as
invalid for DMA write operations originating from Ethernet, USB,
SD and any other DMA capable south-cluster component on VC0.
Similarly it is possible to mark kernel memory as non-SMM mode
read/write only or to mark BIOS runtime memory as SMM mode
accessible only depending on the particular memory footprint on
a given system.
On an IMR violation Quark SoC X1000 systems are configured to
reset the system, so ensuring that the IMR memory map is
consistent with the EFI provided memory map is critical to
ensure no IMR violations reset the system.
The API for accessing IMRs is based on MTRR code but doesn't
provide a /proc or /sys interface to manipulate IMRs. Defining
the size and extent of IMRs is exclusively the domain of
in-kernel code.
Quark firmware sets up a series of locked IMRs around pieces of
memory that firmware owns such as ACPI runtime data. During boot
a series of unlocked IMRs are placed around items in memory to
guarantee no DMA modification of those items can take place.
Grub also places an unlocked IMR around the kernel boot params
data structure and compressed kernel image. It is necessary for
the kernel to tear down all unlocked IMRs in order to ensure
that the kernel's view of memory passed via the EFI memory map
is consistent with the IMR memory map. Without tearing down all
unlocked IMRs on boot transitory IMRs such as those used to
protect the compressed kernel image will cause IMR violations and system reboots.
The IMR init code tears down all unlocked IMRs and sets a
protective IMR around the kernel .text and .rodata as one
contiguous block. This sanitizes the IMR memory map with respect
to the EFI memory map and protects the read-only portions of the
kernel from unwarranted DMA access.

This patch makes the toshiba_eco_mode_available function more robust

returning 0x8300 (Input Data Error) when it is, however, there are
some BIOSes that have stub function calls not returning anything and
and the LED device was being registered too, hence the change of the
default return value from 1 to 0.

Some Samsung laptops with SABI3 delay the sleep for 10 seconds after
the lid is closed and do not wake up from sleep after the lid is opened.
A SABI command is needed to enable the better behavior.
Command = 0x6e, d0 = 0x81 enables this behavior. Returns d0 = 0x01.
Command = 0x6e, d0 = 0x80 disables this behavior. Returns d0 = 0x00.
Command = 0x6d and any d0 queries the state. This returns:
d0 = 0x00000*01, d1 = 0x00, d2 = 0x00, d3 = 0x0* when it is enabled.
d0 = 0x00000*00, d1 = 0x00, d2 = 0x00, d3 = 0x0* when it is disabled.
Where * is 0 - laptop has never slept or hibernated after switch on,
1 - laptop has hibernated just before,
2 - laptop has slept just before.
Patch addresses bug https://bugzilla.kernel.org/show_bug.cgi?id=75901 .
It adds a sysfs attribute lid_handling with a description and also an
addition to the quirks structure to enable the mode by default.
A user with another laptop in the bug report says that "power button has
to be pressed twice to wake the machine" when he or she enabled the mode
manually using the SABI command. Therefore, it is enabled by default
only for the single laptop that I have tested.

This patch checks whether we receive TOS_NOT_SUPPORTED and returns

In the case that some laptops really do not support the SCI, all the
SCI dependent functions check for TOS_NOT_SUPPORTED, and thus, not
registering support for the queried feature.

Since kernel 3.14 the backlight control has been broken on various Samsung
Atom based netbooks. This has been bisected and this problem happens since
commit b35684b8fa ("drm/i915: do full backlight setup at enable time")
This has been reported and discussed in detail here:
http://lists.freedesktop.org/archives/intel-gfx/2014-July/049395.html
Unfortunately no-one has been able to fix this. This only affects Samsung
Atom netbooks, and the Linux kernel and the BIOS of those laptops have never
worked well together. All affected laptops already have a quirk to avoid using
the standard acpi-video interface and instead use the samsung specific SABI
interface which samsung-laptop uses. It seems that recent fixes to the i915
driver have also broken backlight control through the SABI interface.
The intel_backlight driver OTOH works fine, and also allows for finer grained
backlight control. So add a new use_native_backlight quirk, and replace the
broken_acpi_video quirk with this quirk for affected models. This new quirk
disables acpi-video as before and also stops samsung-laptop from registering
the SABI based samsung_laptop backlight interface, leaving only the working
intel_backlight interface.
This commit enables this new quirk for 3 models which are known to be affected,
chances are that it needs to be used on other models too.

thinkpad-acpi:
acpi: Remove _OSI(Linux) for ThinkPads
thinkpad-acpi: Try to use full software mute control
Signed-off-by: Darren Hart <dvhart@linux.intel.com>
ThinkPads have hardware volume controls and three buttons to control
them. (These are separate from the standard mixer.) By default,
the buttons are:
- Mute: Mutes the hardware volume control and, on some models,
generates KEY_MUTE.
- Up: Unmutes, generates KEY_VOLUMEUP, and increases volume if
applicable. (Newer thinkpads only have hardware mute/unmute.)
- Down: Unmutes, generates KEY_VOLUMEDOWN, and decreases volume
if applicable.
This behavior is unfortunate, since modern userspace will also
handle the hotkeys and change the other mixer. If the software
mixer is muted and the hardware mixer is unmuted and you push mute,
hilarity ensues as they both switch state.
Rather than adding a lot of complex ALSA integration to fix this,
just disable the special ThinkPad volume controls when possible.
This turns the mute and volume buttons into regular buttons, and
standard software controls will work as expected.
ALSA already knows about the mute light on models with a mute light,
so everything should just work.
This should also allow us to remove _OSI(Linux) for all ThinkPads.
For future reference: It turns out that we can ask ACPI for one of
three behaviors directly on very new models. They are "latch" (the
default), "none" (no automatic control), and "toggle" (mute unmutes
when muted). All of the modes besides "none" seem to be a bit
buggy, though, and there doesn't seem to be a consistent way to get
any notification when the HW mute state is changed.

This patch adds support for configuring keyboard backlight settings on supported
Dell laptops. It exports kernel leds interface and uses Dell SMBIOS tokens or
keyboard class interface.
With this patch it is possible to set:
* keyboard backlight level
* timeout after which will be backlight automatically turned off
* input activity triggers (keyboard, touchpad, mouse) which enable backlight
* ambient light settings
Settings are exported via sysfs:
/sys/class/leds/dell::kbd_backlight/
Code is based on newly released documentation by Dell in libsmbios project.
Thanks to Dan Carpenter who reported bug about unpredictable results in

The WMI buffer can contain multiple events. First value in buffer is
length of event followed by data of specified length. After that is next
length and next data. When length is zero then there is no more events
in bufffer.
This patch adds support for processing all events in buffer (not only
first) and parse more event types (not only hotkey events). Because of
variable length of events sometimes BIOS fills more hotkeys (or other
values) into single WMI event. In this case this patch also processes
these multiple hotkeys (and not only first one).
Some event types are just ignored because kernel is not interested in
them (e.g. NIC Link status, battery unplug, ...).
This patch is based on DSDT table from Dell Latitude E6440. Code should
be backward compatible so will process other events of old types same as
before this patch.
This patch also fixes a problem with unknown WMI event messages being
written to the log. Now all known events are parsed and those which are
not interesting to the kernel are dropped without an unknown WMI event
message.

the KAV80 is somewhat unique in that it is the only Acer model where we
fall back to acer-wmi after blacklisting, rather then using the native

was renamed to strncasecmp, and strnicmp made into a wrapper for the new

Pull ACPI and power management updates from Rafael Wysocki:
"Features-wise, to me the most important this time is a rework of
wakeup interrupts handling in the core that makes them work
consistently across all of the available sleep states, including
suspend-to-idle. Many thanks to Thomas Gleixner for his help with
this work.
Second is an update of the generic PM domains code that has been in
need of some care for quite a while. Unused code is being removed, DT
support is being added and domains are now going to be attached to
devices in bus type code in analogy with the ACPI PM domain. The
majority of work here was done by Ulf Hansson who also has been the
most active developer this time.
Apart from this we have a traditional ACPICA update, this time to
upstream version 20140828 and a few ACPI wakeup interrupts handling
patches on top of the general rework mentioned above. There also are
several cpufreq commits including renaming the cpufreq-cpu0 driver to
cpufreq-dt, as this is what implements generic DT-based cpufreq
support, and a new DT-based idle states infrastructure for cpuidle.
In addition to that, the ACPI LPSS driver is updated, ACPI support for
Apple machines is improved, a few bugs are fixed and a few cleanups
are made all over.
Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
maintained by Kevin Hilman that will be merged through the PM tree.
Numbers-wise, the generic PM domains update takes the lead this time
with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
place goes to the wakeup interrupts handling rework (13 commits).

This means c->cur can never be less than zero. Besides that, the actual

In the instantiation of the fan1_input device attribute, NULL is passed
as set function to store_sys_hwmon. The function pointer is never
checked before dereferencing it. This is fine if we can guarantee that
it will never be called with an invalid pointer, but we can't. If
someone from user space decides to change the permissions on this
attribute and write to it, kernel will crash.
Introduce EEEPC_CREATE_SENSOR_ATTR_RO() to instantiate a read-only
attribute, and declare fan1_input with it. This ensures store_sys_hwmon
is never called with NULL parameters. If someone tries to write the
attribute, the system will at least keep its sanity.
This also causes EEEPC_CREATE_SENSOR_ATTR() to be only used for R/W
attributes.This enables us to drop the _mode argument from the macro
and use DEVICE_ATTR_RW() internally while we're at it. Append _RW to the
name for readability.

The disp attribute is write-only, but sysfs doesn't know this. Currently
show_sys_acpi() is mimicking sysfs behavior, if the underlying acpi call
should fail. This was introduced in 6dff29b63a "eeepc-laptop:
disp attribute should be write-only". This is not ideal; behaving like
sysfs is better left to sysfs.
Introduce EEEPC_CREATE_DEVICE_ATTR_WO() to instantiate a write-only
attribute, and declare the disp attribute with it. Sysfs makes sure
userspace can only write to disp at all times. This removes the need for
mimicking the sysfs behavior in show_sys_acpi() and store_sys_acpi(),
but we'll stick with -EIO, as changing sysfs return values should not be
taken lightly.
This change also causes EEEPC_CREATE_DEVICE_ATTR() to be used only for
R/W attributes. This enables us to drop the _mode argument from the

parse_arg() has three possible return values:
-EINVAL if sscanf(), in short, fails;
zero if "count" is zero; and
"count" in all other cases
But "count" will never be zero. See, parse_arg() is called by the
various store functions. And the callchain of these functions starts
with sysfs_kf_write(). And that function checks for a zero "count". So
we can stop checking for a zero "count", drop the "count" argument
entirely, and transform parse_arg() into a function that returns zero on
success or a negative error. That, in turn, allows to make those store
functions just return "count" on success. The net effect is that the
code becomes a bit easier to understand.
A nice side effect is that this GCC warning is silenced too:
drivers/platform/x86/eeepc-laptop.c: In function ‘store_sys_acpi’:
drivers/platform/x86/eeepc-laptop.c:279:10: warning: ‘value’ may be used uninitialized in this function [-Wmaybe-uninitialized]

with the return status of at least on of the device_create_file() call.
We can return directly in case the first file creation fails.
All the labels for goto can be removed (along with the gotos) as well.
Tell the compiler that the failures are unlikely so it can create better

Newer Toshiba models now come with a new (and different) keyboard
backlight implementation with three modes of operation: TIMER,
ON and OFF, and the LED is now controlled internally by the firmware.
This patch adds support for that type of backlight, changing the
existing code to accomodate the new implementation.
The timeout value range is now 1-60 seconds, and the accepted
modes are now: 1 (FN-Z), 2 (AUTO or TIMER), 8 (ON) and 10 (OFF),
this adds two new entries kbd_type and available_kbd_modes,
the first shows the keyboard type and the latter shows the
supported modes depending on the keyboard type.

Fujitsu backlight and hotkey devices have ACPI drivers.
The PNP MODULE_DEVICE_TABLE in fujitsu-laptop driver is just used as an
indicator for module autoloading, but this is wrong because what we
need is ACPI module device table instead, because the driver is probing
ACPI devices.
Thus remove those IDs from ACPI PNP scan handler list as we don't
have a PNP driver for them, and convert the fujitsu-laptop PNP
MODULE_DEVICE_TABLE to ACPI MODULE_DEVICE_TABLE.

The current code just returns -EINVAL because mode can't be equal to
both 1 and 2.
Also this function is messy so I have cleaned it up:
1) Remove initializers like "int time = -1". Initializing variables to
garbage values turns off GCC's uninitialized variable warnings so it
can lead to bugs.
2) Use kstrtoint() instead of sscanf().
3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1
and 2.
4) Don't check for "mode == -1" because that can't happen.
5) Preserve the error code from toshiba_kbd_illum_status_set().

I've received a bug report from a user that the touchpad control part
of the ideapad-laptop ACPI interface does work for him on his
"Lenovo Yoga 2 13", and that this patch causes a regression for him.
Since it did not work for me when I had a "Lenovo Yoga 2 11" in my own
hands (loaned from a friend). It seems that this is a bit of hit and miss.
Since the result of having a false positive here is worse, then the minor
annoyance of a false touchpad disabled messages being shown after suspend /
resume on models (or is it firmware versions?) where the interface does not
work, simply revert the patch.
This reverts commit f79a901331.

When bl_power support got added to asus-wmi, the error handling for it was
written to ignore -ENODEV, to avoid not registering a backlight interface for
models which have no bl_power control, but do have brightness control.
At the same time the error handling for brightness_max was modified to do the
same, this is wrong, when there is no brightness_max asus-wmi should not
register a backlight interface.
Note the caller of asus_wmi_backlight_init already special cases -ENODEV,
and will not cause the wmi driver regristration to fail because of a
-ENODEV return from asus_wmi_backlight_init.

It seems that the same problems which lead to adding an rfkill blacklist and
putting the Lenovo Yoga 2 11 on it are also present on the Lenovo Yoga 2 13
and Lenovo Yoga 2 Pro too:
https://bugzilla.redhat.com/show_bug.cgi?id=1021036https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/1517612
Testing has shown that the firmware rfkill settings are persistent over
reboots. So blacklisting the driver is not good enough, if the wifi is blocked
at the firmware level the wifi needs to be explictly unblocked through the
ideapad-laptop interface.
And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices
with hardware kill switch reports the hardware switch state, needs to be
explictly set to 1 (radio enabled / not blocked).
So this patch does 3 things to get proper rfkill handling on these models:
1) Instead of blacklisting the rfkill functionality, which means that people
with a firmware blocked wifi get stuck in that situation, ignore the value
reported by the not present hardware rfkill switch, as this is what is causing
ideapad-laptop to wrongly report all radios as hardware blocks. But do register
the rfkill interfaces so that the user can soft [un]block them.
2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1
3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2
series is affected.

Merge tag 'v3.16-rc6' into next
Merge with mainline to bring in changes to MFD to allow merging
ipaq-micro-ts driver.
The existing implementation which encodes the configuration as a binary
blob in platform data is unsatisfactory since it requires a kernel
recompile for the configuration to be changed, and it doesn't deal well
with firmware changes that move values around on the chip.
Atmel define an ASCII format for the configuration which can be exported
from their tools. This patch implements a parser for that format which
loads the configuration via the firmware loader and sends it to the MXT
chip.

Limit the number of times we allow deferred probing to attempt to add
i2c devices. This will help with some device flakiness at probe time.
For example, some touchpads and touchscreens may be in transition between
bootloader and operational mode and may appear at neither address briefly.
Adapters, however, have no limit as it depends on when the i2c adapter driver
module is loaded. The module may even be loaded manually by the user using
modprobe or insmod.
By default, set MAX_I2C_DEVICE_DEFERALS to 5.

Turns out that DMI_SYSTEM_VENDOR is actually the native vendor of each
Chromebook/box. I tested the original patch on a Pixel that -- surprise,
has Google as vendor. *facepalm*.
The only other data I can think of to probe on is Google_* in the version
string. Checking with our firmware team, all systems should have this
and nothing else than Chrome hardware should have the coreboot + Google_*
combination to date.
So, we'll switch to this. For future platforms we are going to move to
using an ACPI device to configure this instead of a DMI table (yay!),
so longer-term that will sort itself out.

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.

It's fairly difficult to fix the drm_fb problem and a quick fix isn't

just to call this earlier.

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

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

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.

Hi all,
my panasonic cf-51 does no longer react to the suspend and hibernate
keys. I cannot tell when this started since I no longer use the machine
on a daily basis, but I suspect it started when userspace switched from
using /proc/acpi/event to the input layer, wich was quite some time ago ;-)
Today I investigated the issue and found that the firmware simply does
not generate any event on "key down" for those keys, but only on "key up".
The attached patch works around the problem.
Best regards,
Stefan

At least on my CF-51, both sleep and hibernate keys do not
generate "key down" events, only "key up". Because of this,
the input layer does ignore both keys. The work around is
to generate a key down event before the key up. To avoid
double events on non-broken firmware, this is only done if
no key down is ever seen for those keys.

There have been lots of changes in ALSA core, HD-audio and ASoC, also
most of PCI drivers touched by conversions of printks. All these
resulted in a high volume and wide ranged patch sets in this release.
Many changes are fairly trivial, but also lots of nice cleanups and
refactors. There are a few new drivers, most notably, the Intel
Haswell and Baytrail ASoC driver.
Core changes:
- A bit modernization; embed the device struct into snd_card struct,
so that it may be referred from the beginning. A new snd_card_new()
function is introduced for that, and all drivers have been
converted.
- Simplification in the device management code in ALSA core;
now managed by a simple priority list instead
- Converted many kernel messages to use the standard dev_err() & co;
this would be the pretty visible difference, especially for
HD-audio.
HD-audio:
- Conexant codecs use the auto-parser as default now;
the old static code still remains in case of regressions.
Some old quirks have been rewritten with the fixups for auto-parser.
- C-Media codecs also use the auto-parser as default now, too.
- A device struct is assigned to each HD-audio codec, and the formerly
hwdep attributes are accessible over the codec sysfs, too.
hwdep attributes still remain for compatibility.
- Split the PCI-specific stuff for HD-audio controller into a separate
module, ane make a helper module for the generic controller driver.
This is a preliminary change for supporting Tegra HDMI controller in
near future, which slipped from 3.15 merge.
- Device-specific fixes: mute LED support for Lenovo Ideapad,
mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more
Dell laptop headset quirks
- Make the HD-audio codec response a bit more robust
- A few improvements on Realtek ALC282 / 283 about the pop noises
- A couple of Intel HDMI fixes
ASoC:
- Lots of cleanups for enumerations; refactored lots of error prone
original codes to use more modern APIs
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle
- Provide both manually and transparently locked DAPM APIs rather than
a mix of the two fixing some concurrency issues
- Start converting CODEC drivers to use separate bus interface drivers
rather than having them all in one file helping avoid dependency
issues
- DPCM support for Intel Haswell and Bay Trail platforms, lots of
fixes
- Lots of work on improvements for simple-card, DaVinci and the Renesas
rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8
- Fixes for the simple-card DAI format DT mess
- DT support for a couple more devices.
- Use of the tdm_slot mapping in a few drivers
Others:
- Support of reset_resume callback for improved S4 in USB-audio driver;
the device with boot quirks have been little tested, which we need
to watch out in this development cycle
- Add PM support for ICE1712 driver (finally!);
it's still pretty partial support, only for M-Audio devices

Many changes are fairly trivial, but also lots of nice cleanups and
refactors. There are a few new drivers, most notably, the Intel
Haswell and Baytrail ASoC driver.
Core changes:
- A bit modernization; embed the device struct into snd_card struct,
so that it may be referred from the beginning. A new
snd_card_new() function is introduced for that, and all drivers
have been converted.
- Simplification in the device management code in ALSA core; now
managed by a simple priority list instead
- Converted many kernel messages to use the standard dev_err() & co;
this would be the pretty visible difference, especially for
HD-audio.
HD-audio:
- Conexant codecs use the auto-parser as default now; the old static
code still remains in case of regressions. Some old quirks have
been rewritten with the fixups for auto-parser.
- C-Media codecs also use the auto-parser as default now, too.
- A device struct is assigned to each HD-audio codec, and the
formerly hwdep attributes are accessible over the codec sysfs, too.
hwdep attributes still remain for compatibility.
- Split the PCI-specific stuff for HD-audio controller into a
separate module, ane make a helper module for the generic
controller driver. This is a preliminary change for supporting
Tegra HDMI controller in near future, which slipped from 3.15
merge.
- Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED
fix for HP laptops, more ASUS subwoofer quirks, yet more Dell
laptop headset quirks
- Make the HD-audio codec response a bit more robust
- A few improvements on Realtek ALC282 / 283 about the pop noises
- A couple of Intel HDMI fixes
ASoC:
- Lots of cleanups for enumerations; refactored lots of error prone
original codes to use more modern APIs
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle
- Provide both manually and transparently locked DAPM APIs rather
than a mix of the two fixing some concurrency issues
- Start converting CODEC drivers to use separate bus interface
drivers rather than having them all in one file helping avoid
dependency issues
- DPCM support for Intel Haswell and Bay Trail platforms, lots of
fixes
- Lots of work on improvements for simple-card, DaVinci and the
Renesas rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of
the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8
- Fixes for the simple-card DAI format DT mess
- DT support for a couple more devices.
- Use of the tdm_slot mapping in a few drivers
Others:
- Support of reset_resume callback for improved S4 in USB-audio
driver; the device with boot quirks have been little tested, which
we need to watch out in this development cycle
- Add PM support for ICE1712 driver (finally!); it's still pretty
partial support, only for M-Audio devices"

Pull ACPI and power management updates from Rafael Wysocki:
"As far as the number of commits goes, the top spot belongs to ACPI
this time with cpufreq in the second position and a handful of PM
core, PNP and cpuidle updates. They are fixes and cleanups mostly, as
usual, with a couple of new features in the mix.
The most visible change is probably that we will create struct
acpi_device objects (visible in sysfs) for all devices represented in
the ACPI tables regardless of their status and there will be a new
sysfs attribute under those objects allowing user space to check that
status via _STA.
Consequently, ACPI device eject or generally hot-removal will not
delete those objects, unless the table containing the corresponding
namespace nodes is unloaded, which is extremely rare. Also ACPI
container hotplug will be handled quite a bit differently and cpufreq
will support CPU boost ("turbo") generically and not only in the
acpi-cpufreq driver.
Specifics:
- ACPI core changes to make it create a struct acpi_device object for
every device represented in the ACPI tables during all namespace
scans regardless of the current status of that device. In
accordance with this, ACPI hotplug operations will not delete those
objects, unless the underlying ACPI tables go away.

These functions mix the use of result and error. In acpi_fujitsu_add,
result does not seem useful; it would seem reasonable to propagate the
return value of acpi_bus_update_power in an error case. On the other hand,
in the case of acpi_fujitsu_hotkey_add, there is an initialization of
result that can lead to what looks like a failure case, but that does not
abort the function. The variable result is kept for this case.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

Installing the i8042 filter is not useful on machines where rfkill is not
whitelisted, so move the filter installation into dell_setup_rfkill,
after the whitelist check.
This avoids doing a needless and potentially troublesome rfkill query
(dell_send_request(buf, 17, 11)) when the wireless Fn key gets pressed on
non whitelisted laptops.
This patch was written as a result of:
https://bugzilla.redhat.com/show_bug.cgi?id=1045807
It is not yet clear if this is related, but it is a good idea to not register
