From 8343ba2d4820b1738bbb7cb40ec18ea0a3b0b331 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Fri, 24 May 2019 12:27:01 +0200 Subject: [PATCH] KVM: selftests: enable pgste option for the linker on s390 To avoid testcase failures we need to enable the pgstes. This can be done with /proc/sys/vm/allocate_pgste or with a linker option that creates an S390_PGSTE program header.
