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." * 'x86-acpi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: X86 ACPI: Use #ifdef not #if for CONFIG_X86 check ACPI: Fix build when disabled ACPI: Document ACPI table overriding via initrd ACPI: Create acpi_table_taint() function to avoid code duplication ACPI: Implement physical address table override ACPI: Store valid ACPI tables passed via early initrd in reserved memblock areas x86, acpi: Introduce x86 arch specific arch_reserve_mem_area() for e820 handling lib: Add early cpio decoder
