Merge branches 'x86-cpu-for-linus' and 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpu and fpu updates from Ingo Molnar:
- math-emu fixes
- CPUID updates
- sanity-check RDRAND output to see whether the CPU at least pretends
to produce random data
- various unaligned-access across cachelines fixes in preparation of
hardware level split-lock detection
- fix MAXSMP constraints to not allow !CPUMASK_OFFSTACK kernels with
larger than 512 NR_CPUS
- misc FPU related cleanups
