Subject: [PATCH 5.4 073/222] s390/setup: Fix secure ipl message

From: Philipp Rudo <prudo@...ux.ibm.com>

commit 40260b01d029ba374637838213af500e03305326 upstream.

The new machine loader on z15 always creates an IPL Report block and
thus sets the IPL_PL_FLAG_IPLSR even when secure boot is disabled. This
causes the wrong message being printed at boot. Fix this by checking for
IPL_PL_FLAG_SIPL instead.

Fixes: 9641b8cc733f ("s390/ipl: read IPL report at early boot")
