From 0b6529e3dc1c60565f10ccf40533b127ab3262a1 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 11 Sep 2023 21:40:09 +0200 Subject: s390/setup: make use of system_ctl_load() Use system_ctl_load() instead of local_ctl_load() to reflect that control register changes are supposed to be global. Even though setup_cr() was ok, note that the usage of local_ctl_load() would have been wrong, if it would have happened after the control register save area was initialized: only local control register contents would have been changed, but wouldn't be used for new CPUs. With using system_ctl_load() the caller doesn't need to take care.
