Subject: [PATCH 2/2] efi: Allow efi=runtime
Git-commit: 720dff78de360ad9742d5f438101cedcdb5dad84
Patch-mainline: v5.16-rc1
References: bsc#1189998
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.
This is useful on PREEMPT_RT where "efi=noruntime" is default and the
user might need to alter the boot order for instance.
