Merge branch 'x86-acpi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 ACPI update from Peter Anvin:
"This is a patchset which didn't make the last merge window. It adds a
debugging capability to feed ACPI tables via the initramfs.
On a grander scope, it formalizes using the initramfs protocol for
feeding arbitrary blobs which need to be accessed early to the kernel:
they are fed first in the initramfs blob (lots of bootloaders can
concatenate this at boot time, others can use a single file) in an
uncompressed cpio archive using filenames starting with "kernel/".
The ACPI maintainers requested that this patchset be fed via the x86
tree rather than the ACPI tree as the footprint in the general x86
code is much bigger than in the ACPI code proper."
