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

Pull EFI updates from Ingo Molnar:
 "Main changes in this cycle were:

   - Refactor the EFI memory map code into architecture neutral files
     and allow drivers to permanently reserve EFI boot services regions
     on x86, as well as ARM/arm64. (Matt Fleming)

   - Add ARM support for the EFI ESRT driver. (Ard Biesheuvel)

   - Make the EFI runtime services and efivar API interruptible by
     swapping spinlocks for semaphores. (Sylvain Chouleur)

   - Provide the EFI identity mapping for kexec which allows kexec to
     work on SGI/UV platforms with requiring the "noefi" kernel command
     line parameter. (Alex Thorlton)

   - Add debugfs node to dump EFI page tables on arm64. (Ard Biesheuvel)

   - Merge the EFI test driver being carried out of tree until now in
     the FWTS project. (Ivan Hu)

   - Expand the list of flags for classifying EFI regions as "RAM" on
     arm64 so we align with the UEFI spec. (Ard Biesheuvel)

   - Optimise out the EFI mixed mode if it's unsupported (CONFIG_X86_32)
     or disabled (CONFIG_EFI_MIXED=n) and switch the early EFI boot
     services function table for direct calls, alleviating us from
     having to maintain the custom function table. (Lukas Wunner)

   - Miscellaneous cleanups and fixes"
