Linus Torvalds e5b3fc125d Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
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"
