The file permissions of cpufreq per-cpu sysfs files are not preserved
across suspend/resume because we internally go through the CPU
Hotplug path which reinitializes the file permissions on CPU online.
But the user is not supposed to know that we are using CPU hotplug
internally within suspend/resume (IOW, the kernel should not silently
wreck the user-set file permissions across a suspend cycle).
Therefore, we need to preserve the file permissions as they are
across suspend/resume.
The simplest way to achieve that is to just not touch the sysfs files
at all - ie., just ignore the CPU hotplug notifications in the
suspend/resume path (_FROZEN) in the cpufreq hotplug callback.

Following commit 6b772e8f9 (ACPI: Update PNPID match handling for
notify), the acpi_scan_init_hotplug() calls acpi_set_pnp_ids() which
allocates acpi_hardware_id and copies a few strings (kstrdup). If the
devices does not have hardware_id set, the function exits without
freeing the previously allocated ids (and kmemleak complains). This
patch calls simply changes 'return' on error to a 'goto out' which
calls acpi_free_pnp_ids().

The ffmpeg benchmark in the phoronix test suite has threads on
multiple cores that rely on the progress on of threads on other cores
and ping pong back and forth fast enough to make the core appear less
busy than it "should" be. If the core has been at minimum p-state for
a while bump the pstate up to kick the core to see if it is in this
ping pong state. If the core is truly idle the p-state will be
reduced at the next sample time. If the core makes more progress it
will send more work to the thread bringing both threads out of the
ping pong scenario and the p-state will be selected normally.
This fixes a performance regression of approximately 30%

The acpi-thermal driver adjusts the p-state policy in response to

Use the lowest of the two requested values this ensures that we will

With commit 1e4b545, regulator_get will now return -EPROBE_DEFER
when the cpu0-supply node is present, but the regulator is not yet
registered.
It is possible for this to occur when the regulator registration
by itself might be defered due to some dependent interface not yet
instantiated. For example: an regulator which uses I2C and GPIO might
need both systems available before proceeding, in this case, the
regulator might defer it's registration.
However, the cpufreq-cpu0 driver assumes that any un-successful
return result is equivalent of failure.
When the regulator_get returns failure other than -EPROBE_DEFER, it
makes sense to assume that supply node is not present and proceed
with the assumption that only clock control is necessary in the
platform.
With this change, we can now handle the following conditions:
a) cpu0-supply binding is not present, regulator_get will return
appropriate error result, resulting in cpufreq-cpu0 driver
controlling just the clock.
b) cpu0-supply binding is present, regulator_get returns
-EPROBE_DEFER, we retry resulting in cpufreq-cpu0 driver
registering later once the regulator is available.
c) cpu0-supply binding is present, regulator_get returns
-EPROBE_DEFER, however, regulator never registers, we retry until
cpufreq-cpu0 driver fails to register pointing at device tree
information bug. However, in this case, the fact that
cpufreq-cpu0 operates with clock only when the DT binding clearly
indicates need of a supply is a bug of it's own.
d) cpu0-supply gets an regulator at probe - cpufreq-cpu0 driver
controls both the clock and regulator

- Done only once per governor (doesn't depend how many instances of

- Done per governor instance, eg: sysfs_{create|remove}_group().
There were some corner cases where current code isn't able to handle

We use two separate variables now for keeping track of above two
requirements.

The Thinkpad e530's BIOS notifies the AC device first and then
sleeps for certain amount of time before doing real work in the
EC event handler (_Qxx):
Method (_Q27, 0, NotSerialized)
{
Notify (AC, 0x80)
Sleep (0x03E8)
Store (Zero, PWRS)
PNOT ()
}
This causes the AC driver to report an outdated AC state to user
space, because it reads the state information from the device while
the EC handler is sleeping.
Introduce a quirk to cause the AC driver to wait in acpi_ac_notify()
before calling acpi_ac_get_state() on systems known to have this
problem and add Thinkpad e530 to the list of quirky machines (with
a 1s delay which has been verified to be sufficient for that
machine).

The EC driver works abnormally with IBF flag always set.
IBF means "The host has written a byte of data to the command
or data port, but the embedded controller has not yet read it".
If IBF is set in the EC status and not cleared, this will cause
all subsequent EC requests to fail with a timeout error.
Change the EC driver so that it doesn't refuse to restart a
transaction if IBF is set in the status. Also increase the
number of transaction restarts to 5, as it turns out that 2
is not sufficient in some cases.
This bug happens on several different machines (Asus V1S,
Dell Latitude E6530, Samsung R719, Acer Aspire 5930G,
Sony Vaio SR19VN and others).

The system suspend routine of the ACPI processor driver saves
the BUS_MASTER_RLD register and its resume routine restores it.
However, there can be only one such register in the system and it
really should be saved after non-boot CPUs have been offlined and
restored before they are put back online during resume.
For this reason, move the saving and restoration of BUS_MASTER_RLD
to syscore suspend and syscore resume, respectively, and drop the no
longer necessary suspend/resume callbacks from the ACPI processor
driver.

be2iscsi, pm80xx, qla4x and ipr).
There's also the power management updates that complete the patches in
Jens' tree, an iscsi refcounting problem fix from the last pull, some
dif handling in scsi_debug fixes, a few nice code cleanups and an
error handling busy bug fix."

Pull audit changes from Eric Paris:
"Al used to send pull requests every couple of years but he told me to
just start pushing them to you directly.
Our touching outside of core audit code is pretty straight forward. A
couple of interface changes which hit net/. A simple argument bug
calling audit functions in namei.c and the removal of some assembly
branch prediction code on ppc"

Pull x86 platform drivers from Matthew Garrett:
"Small set of updates, mainly trivial bugfixes and some small updates
to deal with newer hardware.
There's also a new driver that allows qemu guests to notify the
hypervisor that they've just paniced, which seems useful."

apparent on faster storage devices. There's no noticeable change when hardware
crypto is not available.
