From 7a4550314a490c58c0745e75366af53f67d51f70 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Thu, 26 Jul 2018 15:06:10 +0200 Subject: [PATCH 022/166] efi: Allow efi=runtime 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.
