Patches requested by IBM for Spectre v2.

Note that the 3rd patch ("KVM: s390: define GISA format-0") wasn't actually requested but is needed to avoid a compile failure in patch #4.

Build-tested for s390x


Christian Borntraeger (2):
  KVM: s390: implement CPU model only facilities
  KVM: s390: add etoken support for guests

Khalid Elmously (1):
  UBUNTU: SAUCE: bpf, s390x: remove ld_abs/ld_ind

Martin Schwidefsky (3):
  s390: detect etoken facility
  s390/lib: use expoline for all bcr instructions
  s390: fix br_r1_trampoline for machines without exrl

Michael Mueller (1):
  KVM: s390: define GISA format-0 data structure
