------------------ From: Dave Young <dyo...@redhat.com> [ Upstream commit 7f6f60a1ba52538c16f26930bfbcfe193d9d746a ] earlyprintk=efi,keep does not work any more with a warning in mm/early_ioremap.c: WARN_ON(system_state != SYSTEM_BOOTING): Boot just hangs because of the earlyprintk within the earlyprintk implementation code itself. This is caused by a new introduced middle state in: 69a78ff226fe ("init: Introduce SYSTEM_SCHEDULING state") early_ioremap() is fine in both SYSTEM_BOOTING and SYSTEM_SCHEDULING states, original condition should be updated accordingly.
