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%

There are two ways that the maximum p-state can be clamped, via a
policy change and via the sysfs file.

The acpi-thermal driver adjusts the p-state policy in response to
thermal events.  These changes override the users settings at the
moment.

Use the lowest of the two requested values this ensures that we will
not exceed the requested pstate from either mechanism.

Idle time is taken into account in the APERF/MPERF ratio calculation
there is no reason for the driver to track it seperately.  This
reduces the work in the driver and makes the code more readable.

Removal of the tracking of sample duration removes the possibility of
the divide by zero exception when the duration is sub 1us

With commit 1e4b545c, 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
   the governor there are). eg: cpufreq_register_notifier() for
   conservative governor.
 - Done per governor instance, eg: sysfs_{create|remove}_group().

There were some corner cases where current code isn't able to handle
them separately and so failing for some test cases.

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.
