Pull x86 fpu changes from Ingo Molnar:
"There are two main areas of changes:
- Rework of the extended FPU state code to robustify the kernel's
usage of cpuid provided xstate sizes - and related changes (Dave
Hansen)"
- math emulation enhancements: new modern FPU instructions support,
with testcases, plus cleanups (Denys Vlasnko)"
