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A comment-only patch to a change the was due in part to an unpublished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"
