Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux
Pull ACPI and Power Management changes from Len Brown.
This does an evil merge to fix up what I think is a mismerge by Len to
the gma500 driver, and restore it to the mainline state.
In that driver, both branches had commented out the call to
acpi_video_register(), and Len resolved the merge to that commented-out
version.
However, in mainline, further changes by Alan (commit d839ede47a56:
"gma500: opregion and ACPI" to be exact) had re-enabled the ACPI video
registration, so the current state of the driver seems to want it.
Alan is apparently still feeling the effects of partying with the Queen,
so he didn't reply to my query, but I'll do the evil merge anyway.
* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux:
ACPI: fix acpi_bus.h build warnings when ACPI is not enabled
drivers: acpi: Fix dependency for ACPI_HOTPLUG_CPU
tools/power turbostat: fix IVB support
tools/power turbostat: fix un-intended affinity of forked program
ACPI video: use after input_unregister_device()
gma500: don't register the ACPI video bus
acpi_video: Intel video is not always i915
acpi_video: fix leaking PCI references
ACPI: Ignore invalid _PSS entries, but use valid ones
ACPI battery: only refresh the sysfs files when pertinent information changes
