735df29a06 iwlwifi: BA scd_flow not match condition detected
It is a uCode bug which cause the tx queue id not match scd_flow
in compressed block ack frame, and it need to be addressed in uCode.
Currently, driver will log the information when it happen.

Since it is possible happen very often and we do not want to fill the syslog,
so don't enable the logging by default.

iwl-debug.h:73: note: expected ‘void *’ but argument is of type ‘const u8 *’

4254bc1c4d ath9k_hw: fix a noise floor calibration related race condition
On AR5008-AR9002, other forms of calibration must not be started while
the noise floor calibration is running, as this can create invalid
readings which were sometimes not even recoverable by any further
calibration attempts.

This patch also ensures that the result of noise floor measurements
are processed faster and also allows the result of the initial
calibration on reset to make it into the NF history buffer

20bd2a0952 ath9k_hw: clean up per-channel calibration data
The noise floor history buffer is currently not kept per channel, which
can lead to problems when changing channels from a clean channel to a
noisy one. Also when switching from HT20 to HT40, the noise floor
history buffer is full of measurements, but none of them contain data
for the extension channel, which it needs quite a bit of time to recover
from.

This patch puts all the per-channel calibration data into a single data
structure, and gives the the driver control over whether that is used
per-channel or even not used for some channels.

For ath9k_htc, I decided to keep this per-channel in order to avoid
creating regressions.

For ath9k, the data is kept only for the operating channel, which saves
some space. ath9k_hw takes care of wiping old data when the operating
channel or its channel flags change.

5ee0865615 ath9k: prevent calibration during off-channel activity
Previously the software scan callback was used to indicate to the hardware,
when it was safe to calibrate. This didn't really work properly, because it
depends on a specific order of software scan callbacks vs. channel changes.
Also, software scans are not the only thing that triggers off-channel
activity, so it's better to use the newly added indication from mac80211 for
this and not use the software scan callback for anything calibration related.

This fixes at least some of the invalid noise floor readings that I've seen
in AP mode on AR9160

9369746050 ath9k_hw: fix periodic noise floor calibration on AR9003
The periodic noise floor calibration is broken on this chip family, because
it keeps triggering a software-filtered noise floor calibration, but never
reads the result before uploading the history buffer value to the hardware.

Fix this with a call to ath9k_hw_getnf(), just like on AR9002.

00c86590e3 ath9k_hw: clean up and fix initial noise floor calibration
On AR9003 the initial noise floor calibration is currently triggered
at the end of the reset without allowing the hardware to update the
baseband settings. This could potentially make scans in noisy
environments a bit more unreliable, so use the same calibration
sequence that is used on AR9002.

02f5ba5bac iwlwifi: fix possible recursive locking deadlock
commit f84b29ec0a
Author: Johannes Berg <johannes.berg@intel.com>
Date:   Tue May 18 02:29:13 2010 -0700

    iwlwifi: queue user-initiated scan when doing internal scan

introduced a potential deadlock because it calls
ieee80211_scan_completed() with the priv->mutex
held, but mac80211 may call back into iwlwifi
which would lead to recursive locking. Move this
out from under the mutex.

6f4f2723d0 [CPUFREQ] x86 cpufreq: Make trace_power_frequency cpufreq driver independent
and fix the broken case if a core's frequency depends on others.

trace_power_frequency was only implemented in a rather ungeneric way
in acpi-cpufreq driver's target() function only.
-> Move the call to trace_power_frequency to
   cpufreq.c:cpufreq_notify_transition() where CPUFREQ_POSTCHANGE
   notifier is triggered.
   This will support power frequency tracing by all cpufreq drivers

trace_power_frequency did not trace frequency changes correctly when
the userspace governor was used or when CPU cores' frequency depend
on each other.
-> Moving this into the CPUFREQ_POSTCHANGE notifier and pass the cpu
   which gets switched automatically fixes this.

Robert Schoene provided some important fixes on top of my initial
quick shot version which are integrated in this patch:
- Forgot some changes in power_end trace (TP_printk/variable names)
- Variable dummy in power_end must now be cpu_id
- Use static 64 bit variable instead of unsigned int for cpu_id

This is the gpe the EC is connected to and whether the global lock

The io ports used are added to /proc/ioports in another patch.
Beside the fact that /proc/acpi is deprecated for quite some time,
this info is not needed for applications and thus can be moved
to debugfs instead of a public interface like /sys.

49c6c5ff92 ACPI: Remove /proc/acpi/embedded_controller/..
Other patches in this series add the same info to /sys/... and
/proc/ioports.

The info removed should never have been used in an application,
eventually someone read it manually.
/proc/acpi is deprecated for more than a year anyway...

9fab10cdf5 panasonic-laptop: fix acpi_pcc_write_sset return value
In current implementation, acpi_pcc_write_sset return 1
if write is successful, 0 if write is failed.
But all the callers consider acpi_pcc_write_sset return 0
if write is successful and return negtive if write is failed.

This patch changes the implementation of acpi_pcc_write_sset to
return 0 if write is successful, -EIO if write is failed.

must kfree the returned buffer if AE_OK is returned.

Call Trace:

When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER, the caller
must kfree the returned buffer if AE_OK is returned.

The callers of wmi_query_block() pass ACPI_ALLOCATE_BUFFER, and thus must
check its return value before accessing or kfree() on the buffer.

This patch adds a missing kfree(out.pointer) before exit
WMID_set_capabilities() and get_wmid_devices().

1bd1ca1f4c toshiba_acpi: make remove_device() and add_device() void
remove_device() and add_device() are not related to ACPI APIs, it does not
make sense to return acpi_status for both functions.

Current implementation of add_device() always AE_OK, thus the return value
checking for add_device() always return false for ACPI_FAILURE(status).
This patch makes add_device() to be void and remove the unnecessary return
value checking.

remove_proc_entry() won't fail, thus change remove_device() to be void.

a0dba697ee acerhdf: fix resource reclaim in error path
Fix resource reclaim in below cases:

1. acerhdf_register_platform() does not properly handle
   platform_device_alloc() failure and platform_device_add() failure This
   patch adds error handing for acerhdf_register_platform().

2. acerhdf_register_platform() return err with acerhdf_dev == NULL.
   as a result, acerhdf_unregister_platform() does not do resource reclaim
   in acerhdf_init() error path.  This patch adds error handing for
   acerhdf_register_platform(), thus correct the error handing path in
   acerhdf_init().  goto out_err instead of err_unreg if
   acerhdf_register_platform() fail.

3. platform_device_del() should only used in error handling.  Current
   implementation missed a platform_device_put() in acerhdf_exit.  This
   patch fixes it by using platform_device_unregister() instead of
   platform_device_del() in acerhdf_unregister_platform.

9be0fcb5ed compal-laptop: add JHL90, battery & hwmon interface
The driver now supports the Compal JHL90 (which I use) and it has some
added features.  The biggest novelties are a battery interface
(power_supply) and a temperature and fan control interface (hmwon).  It
also adds a power-off feature to the backlight subsystem and it exports a
few files that can enable/disable wake_on_XXX events.

Much of the original code of the old features is still there, but I've
changed some names to keep the naming more coherent with the added
functionalities.  (Sorry for the huge patch)

Some technical stuff about the new driver:

First of all, I'm not sure if the extra features also work on the other
Compal boards.  Currently they only get enabled if the DMI data indicates
you are on a JHL90 board.

Secondly, I've noticed a quirk in my fan controller.  I have to re-send
the wanted pwm-level to the controller every so often.  If I don't do
this, the fanspeed will slowly rise until after a couple of minutes it's
at full speed.  (Note that every normal userland application will probably
update the pwm-level every so often anyway, based on temperature readings,
so this might not be an issue in practice) If this turns out to be a
problem with all the controllers, maybe we should implement a kernel timer
and have the driver re-send the pwm level every XX seconds to make this
transparent to userspace?  (However, I couldn't immediately find a way to
do this cleanly.)

Additional information can be found in the source comments.
