Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull more x86 fixes from Peter Anvin:
"Additional x86 fixes. Three of these patches are pure documentation,
two are pretty trivial; the remaining one fixes boot problems on some
non-BIOS machines."
* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86: Make sure we can boot in the case the BDA contains pure garbage
x86, efi: Mark disable_runtime as __initdata
x86, doc: Fix incorrect comment about 64-bit code segment descriptors
doc, kernel-parameters: Document 'console=hvc<n>'
doc, xen: Mention 'earlyprintk=xen' in the documentation.
ACPI: Overriding ACPI tables via initrd only works with an initrd and on X86
