Subject: efi: Allow efi=runtime
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Date: Thu Jul 26 15:06:10 2018 +0200
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
In case the command line option "efi=noruntime" is default at built-time, the user
could overwrite its state by `efi=runtime' and allow it again.
