Pull ACPI and power management fixes from Rafael Wysocki:
"Three of these are regression fixes, for two recent regressions and
one introduced during the 3.13 cycle, and the fourth one is a working
version of the fix that had to be reverted last time.
Specifics:
- A recent ACPI resources handling fix overlooked the fact that it
had to update the ACPI PNP subsystem's resources parsing too and
caused confusing warning messages to be printed during system
intialization on some systems (with arguably buggy ACPI tables).
Fix from Zhang Rui.
- Moving the early ACPI initialization before timekeeping_init()
earlier in this cycle broke fast TSC calibration on at least one
system, so it needs to be done later, but still before
efi_enter_virtual_mode() to allow the EFI initialization to refer
to ACPI.
- A change related to code duplication reduction in the cpufreq core
inadvertently caused cpufreq intialization to fail for some CPUs
handled by intel_pstate by adding checks that may fail for that
driver, but aren't even necessary when it is used. The issue is
addressed by preventing those checks from run in the configurations
in which they aren't needed.
- If the Hardware Reduced ACPI flag is set in the ACPI tables, system
suspend, hibernation and ACPI power off will only work when special
sleep control and sleep status registeres are provided (their
addresses in the ACPI tables are not zero). If those registers are
not available, the features in question have no chances to work, so
they shouldn't even be regarded as supported. That helps with
power off in particular, because alternative power off methods may
be used then and they may actually work"
