Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
"The x86 updates contain:
- A fix for a longstanding PAT bug, where PAT was reported on CPUs
that do not support it, which leads to wrong caching attributes and
missing MTRR updates
- Prevent overwriting of the e820 firmware table, which causes kexec
kernels to lose the fake mptable which is stored there.
- Cleanup of the UV/BAU code, removing unused code and making local
functions static"
