Pull ACPI fixes from Rafael Wysocki:
"These fix an ACPI tables management issue, an issue related to the
ACPI enumeration of devices and CPU wakeup in the ACPI processor
driver.
Specifics:
- Ensure that the memory occupied by ACPI tables on x86 will always
be reserved to prevent it from being allocated for other purposes
which was possible in some cases (Rafael Wysocki).
- Fix the ACPI device enumeration code to prevent it from attempting
to evaluate the _STA control method for devices with unmet
dependencies which is likely to fail (Hans de Goede).
- Fix the handling of CPU0 wakeup in the ACPI processor driver to
prevent CPU0 online failures from occurring (Vitaly Kuznetsov)"
