From 4f45b90e1c03466202fca7f62eaf32243f220830 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Fri, 28 Dec 2018 10:46:04 +0100 Subject: KVM: s390: add deflate conversion facilty to cpu model This enables stfle.151 and adds the subfunctions for DFLTCC. Bit 151 is added to the list of facilities that will be enabled when there is no cpu model involved as DFLTCC requires no additional handling from userspace, e.g. for migration. Please note that a cpu model enabled user space can and will have the final decision on the facility bits for a guests.
