This is a mix of UEFI and ACPI updates which in my mind should be
separate bug fixes, one for UEFI updates, and one for ACPI since these
are functionally separate.

There are also a considerable amount of changes here plus changes that
affect generic ACPI.  Given that these are drawn from linux-next and are
a large set of patches I'm hesitant to ACK these until they have at
least baked in a bit more and landed in Linus' upstream repo rather than
linux-next.
