Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux

Pull ACPI & Power Management changes from Len Brown:
 - ACPI 5.0 after-ripples, ACPICA/Linux divergence cleanup
 - cpuidle evolving, more ARM use
 - thermal sub-system evolving, ditto
 - assorted other PM bits

Fix up conflicts in various cpuidle implementations due to ARM cpuidle
cleanups (ARM at91 self-refresh and cpu idle code rewritten into
"standby" in asm conflicting with the consolidation of cpuidle time
keeping), trivial SH include file context conflict and RCU tracing fixes
in generic code.

+Description:
+                The BGRT is an ACPI 5.0 feature that allows the OS
+                to obtain a copy of the firmware boot splash and
+                some associated metadata. This is intended to be used
+                by boot splash applications in order to interact with
+                the firmware boot splash in order to avoid jarring
+                transitions.
+
+                image: The image bitmap. Currently a 32-bit BMP.
+                status: 1 if the image is valid, 0 if firmware invalidated it.
+                type: 0 indicates image is in BMP format.
+                version: The version of the BGRT. Currently 1.
+                xoffset: The number of pixels between the left of the screen
+                         and the left edge of the image.
+                yoffset: The number of pixels between the top of the screen
+                         and the top edge of the image.
