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
