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.
