  Specifics:

   - Fix a recent cpuidle core regression that broke suspend-to-idle on

     callbacks for any states (Sudeep Holla).

   - Drop an unnecessary symbol definition from the cpuidle core code

   - Fix a race condition related to governor initialization and removal

   - Clean up the cpufreq core to use list_is_last() for checking if the
     given policy object is the last element of a list instead of open
     coding that in a clumsy way (Gautham R Shenoy).

   - Fix compiler warnings in the pxa2xx and cpufreq-dt cpufreq drivers
     (Arnd Bergmann).

   - Fix two locking issues and clean up a comment in the generic power
     domains framework (Ulf Hansson, Marek Szyprowski, Moritz Fischer).

   - Fix the error code path of one function in the ACPI-based PCI
     hotplug framework (ACPIPHP) that forgets to release a lock acquired
     previously (Insu Yun).

   - Drop the ACPI backlight blacklist entry for Dell Inspiron 5737 that
     is not necessary any more (Hans de Goede).

   - Clean up the top-level PM Kconfig to stop requiring APM emulation

The I2C bus names are supposed to be stable as they can be used by
userspace to uniquely identify a specific I2C bus. So restore the
original names for all legacy (pre-SB800) devices.

For SB800 devices and later, improve the names. "SDA" refers to the
serial data pin of each SMBus port, it's an implementation detail the
user doesn't need to know. Use "port" instead, which is easier to
understand.

Commit 7a786832 ("powerpc/perf: Add an explict flag indicating

the assumption that MMCRA[SLOT] was present when PPMU_ALT_SIPR was not
set.

That commit's changelog also mentions that Power8 does not support
MMCRA[SLOT]. However when the Power8 PMU support was merged, it
errnoeously included the PPMU_HAS_SSLOT flag.

So remove PPMU_HAS_SSLOT from the Power8 flags.

mpe: On systems where MMCRA[SLOT] exists, the field occupies bits 37:39
(IBM numbering). On Power8 bit 37 is reserved, and 38:39 overlap with
the high bits of the Threshold Event Counter Mantissa. I am not aware of
any published events which use the threshold counting mechanism, which
would cause the mantissa bits to be set. So in practice this bug is
unlikely to trigger.

dynamically via sysfs, but it may lead to a memory corruption when
switching is done while a PCM stream is running; the stream instance
for the newly switched timer method tries to access the memory that
was allocated by another timer method although the sizes differ.

As the simplest fix, this patch just disables the switch via sysfs by
dropping the writable bit.
