Merge branch 'tboot' into release

Conflicts:
	drivers/acpi/acpica/hwsleep.c

Text conflict between:

2feec47d4c5f80b05f1650f5a24865718978eea4
(ACPICA: ACPI 5: Support for new FADT SleepStatus, SleepControl registers)

which removed #include "actables.h"

and

09f98a825a821f7a3f1b162f9ed023f37213a63b
(x86, acpi, tboot: Have a ACPI os prepare sleep instead of calling tboot_sleep.)

which removed #include <linux/tboot.h>

The resolution is to remove them both.
