[PATCH tip/sched/core] mm/early_ioremap: Adjust early_ioremap system_state check

From: Tom Lendacky
Date: Wed Jun 14 2017 - 15:12:08 EST


A recent change added a new system_state value, SYSTEM_SCHEDULING, which
exposed a warning issued by early_ioreamp() when the system_state was not
SYSTEM_BOOTING. Since early_ioremap() can be called when the system_state
is SYSTEM_SCHEDULING, the check to issue the warning is changed from
system_state != SYSTEM_BOOTING to system_state >= SYSTEM_RUNNING.
