Pull x86 fixes from Ingo Molnar:
"Various fixes:
- Fix the PAT performance regression that downgraded write-combining
device memory regions to uncached.
- There's been a number of bugs in 32-bit double fault handling -
hopefully all fixed now.
- Fix an LDT crash
- Fix an FPU over-optimization that broke with GCC9 code
optimizations.
- Misc cleanups"
