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 Signed-off-by: Ingo Molnar <mingo@kernel.org>
