Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux
Pull ACPI and power management fixes from Len Brown:
"A 3.3 sleep regression fixed, numa bugfix, plus some minor cleanups"
* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux:
ACPI processor: Fix tick_broadcast_mask online/offline regression
ACPI: Only count valid srat memory structures
ACPI: Untangle a return statement for better readability
ACPI / PCI: Do not try to acquire _OSC control if that is hopeless
ACPI: delete _GTS/_BFS support
ACPI/x86: revert 'x86, acpi: Call acpi_enter_sleep_state via an asmlinkage C function from assembler'
ACPI: replace strlen("string") with sizeof("string") -1
ACPI / PM: Fix build warning in sleep.c for CONFIG_ACPI_SLEEP unset
