Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
"A few updates for x86:
- Fix an unintended sign extension issue in the fault handling code
- Rename the new resource control config switch so it's less
confusing
- Avoid setting up EFI info in kexec when the EFI runtime is
disabled.
- Fix the microcode version check in the AMD microcode loader so it
only loads higher version numbers and never downgrades
- Set EFER.LME in the 32bit trampoline before returning to long mode
to handle older AMD/KVM behaviour properly.
- Add Darren and Andy as x86/platform reviewers"
