Merge branch 'pm-fixes'
on top of commit d683b96b072dc4680fc74964eca77e6a23d1fa6e
These fixes emerged after my previous pull request. They fix one recent
regression, a few regressions introduced in 3.9 and 3.8, and a couple of
long-standing issues. A couple of blacklist entries for systems known
to misbehave are added too.
- Fix for an ACPI PM regression introduced in 3.9 causing Toshiba
P870-303 to crash during boot. From yours truly.
- ACPI fix for an issue causing some drivers to attempt to bind to
devices they shouldn't touch introduced in 3.9 (a broken BIOS is
requisite to trigger this). From Aaron Lu.
- Fix for a recent cpufreq regression related to a possible race with
CPU offline. From Michael Wang.
- Fix for an ACPI cpufreq regression introduced in 3.8 causing turbo
frequencies to be underutilized in some cases. From Ross Lagerwall.
- cpufreq-cpu0 driver fix related to incorrect clock ACPI usage from
- HP WMI driver fix for an issue causing GPS initialization and
poweroff failures on HP Elitebook 6930p. From Lan Tianyu.
- APEI (ACPI Platform Error Interface) fix for an issue in the error
code path in ghes_probe(). From Wei Yongjun.
- New ACPI video driver blacklist entries for HP m4 and HP Pavilion
g6 from Alex Hung and Ash Willis.

Rafael J. Wysocki (1):
ACPI / PM: Do not execute _PS0 for devices without _PSC during initialization
Ross Lagerwall (1):
