Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux
This includes initial support for the recently published ACPI 5.0 spec.
In particular, support for the "hardware-reduced" bit that eliminates
the dependency on legacy hardware.
APEI has patches resulting from testing on real hardware.
Plus other random fixes.
