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
