Merge tag 'efi-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi into x86/urgent

Pull EFI fixes from Matt Fleming:

 * WARN_ON(!spin_is_locked()) always triggers on non-SMP machines.
   Swap it for the more canonical lockdep_assert_held() which always
   does the right thing - Guenter Roeck

 * Assign the correct value to efi.runtime_version on arm64 so that all
   the runtime services can be invoked - Semen Protsenko
