From 1b2be2071aca9aab22e3f902bcb0fca46a1d3b00 Mon Sep 17 00:00:00 2001 From: Philipp Rudo Date: Fri, 28 Jun 2019 17:38:05 +0200 Subject: s390/ipl: Fix detection of has_secure attribute Use the correct bit for detection of the machine capability associated with the has_secure attribute. It is expected that the underlying platform (including hypervisors) unsets the bit when they don't provide secure ipl for their guests.
