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 last regression fixes for 4.8 final:
- Two patches addressing the fallout of the CR4 optimizations which
caused CR4-less machines to fail.
- Fix the VDSO build on big endian machines
- Take care of FPU initialization if no CPUID is available otherwise
task struct size ends up being zero
- Fix up context tracking in case load_gs_index fails"
