fc16c25ff4 [libata] ACPI: remove needless ->qc_issue hook existence test
All drivers must implement this hook, otherwise ATA commands would go
nowhere (and a lot of other oopsen would appear as well).

9de1cc9c44 [PATCH] libata: wrong sizeof for BUFFER
I have reproduced the AE_AML_BUFFER_LIMIT exception mentioned in
<http://bugzilla.kernel.org/show_bug.cgi?id=7689> basing on the SSDT ASL
code and libata ata_acpi_push_id() code.  There is an oversight in
ata_acpi_push_id() causing the exception.  The following update fixes it:

7ea1fbc2a2 [PATCH] libata: ACPI _SDD support
_SDD (Set Device Data) is an ACPI method that is used to tell the
firmware what the identify data is of the device that is attached to
the port.  It is an optional method, and it's ok for it to be missing.
Because of this, we always return success from the routine that calls
this method, even if the execution fails.

11ef697b37 [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.
