Merge branch 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 FPU changes from Ingo Molnar:
"There are two bigger changes in this tree:
- Add an [early-use-]safe static_cpu_has() variant and other
robustness improvements, including the new X86_DEBUG_STATIC_CPU_HAS
configurable debugging facility, motivated by recent obscure FPU
code bugs, by Borislav Petkov
- Reimplement FPU detection code in C and drop the old asm code, by
Peter Anvin."
* 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86, fpu: Use static_cpu_has_safe before alternatives
x86: Add a static_cpu_has_safe variant
x86: Sanity-check static_cpu_has usage
x86, cpu: Add a synthetic, always true, cpu feature
x86: Get rid of ->hard_math and all the FPU asm fu
