[PATCH] libata: ACPI and _GTF support

Browse Source 
_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.

This option adds support for SATA-related ACPI objects.
These ACPI objects add the ability to retrieve taskfiles
from the ACPI BIOS and write them to the disk controller.
These objects may be related to performance, security,
power management, or other areas.
You can disable this at kernel boot time by using the
option libata.noacpi=1
