Subject: [PATCH 018/353] efi: Allow efi=runtime
Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=a72511f8ea9247ecac927b587eeb0813d4ed5505
In case the option "efi=noruntime" is default at built-time, the user
could overwrite its sate by `efi=runtime' and allow it again.
