Subject: [PATCH 0/4] KVM: s390: Fix minor bugs in STFLE shadowing

Fix two bugs in the STFLE vsie implementation.
The first concerns the identification if the guest is intending
to use interpretive execution for STFLE for its guest.
The second fixes too much of the guests memory being accessed when
shadowing.

Nina Schoetterl-Glausch (4):
  KVM: s390: vsie: Fix STFLE interpretive execution identification
  KVM: s390: vsie: Fix length of facility list shadowed
  KVM: s390: cpu model: Use previously unused constant
  KVM: s390: Minor refactor of base/ext facility lists
