[PATCH] libata: ACPI and _GTF support
_GTF is an acpi method that is used to reinitialize the drive. It returns a task file containing ata commands that are sent back to the drive to restore it to boot up defaults. Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org> (cherry picked from 9c69cab24b51a89664f4c0dfaf8a436d32117624 commit)
