Merge branch 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Browse source 
Pull EFI updates from Thomas Gleixner:
 "The EFI pile:

   - Make mixed mode UEFI runtime service invocations mutually
     exclusive, as mandated by the UEFI spec

   - Perform UEFI runtime services calls from a work queue so the calls
     into the firmware occur from a kernel thread

   - Honor the UEFI memory map attributes for live memory regions
     configured by UEFI as a framebuffer. This works around a coherency
     problem with KVM guests running on ARM.

   - Cleanups, improvements and fixes all over the place"
