Merge branch 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 and EFI fixes from Peter Anvin: "Half of these are EFI-related: The by far biggest change is the change to hold off the deletion of a sysfs entry while a backend scan is in progress. This is to avoid calling kmemdup() while under a spinlock. The other major change is for each entry in the EFI pstore backend to get a unique identifier, as required by the pstore filesystem proper. The other changes are: A fix to the recent consolidation and optimization of using "asm goto" with read-modify-write operation, which broke the bitops; specifically in such a way that we could end up generating invalid code. A build hack to make sure we compile with -mno-sse. icc, and most likely future versions of gcc, can generate SSE instructions unless we tell it not to. A comment-only patch to a change the was due in part to an unpublished erratum; now when the erratum is published we want to add a comment explaining why" * 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/apic, doc: Justification for disabling IO APIC before Local APIC x86, bitops: Correct the assembly constraints to testing bitops x86-64, build: Always pass in -mno-sse efi-pstore: Make efi-pstore return a unique id x86/efi: Fix earlyprintk off-by-one bug efivars, efi-pstore: Hold off deletion of sysfs entry until the scan is completed
