The first two patches are modified patches from:
    [PATCH-for-4.2 v1 0/9] s390x: MMU changes and extensions

This series primarily fixes minor things in the storage key handling code
in the MMU and implements fairly reliable reference and change bit handling
for TCG. To track the reference and change bit, we have to invalidate
TLB entries whenever the storage key is changed by the guest and make sure
not TLB entry is writable in case the storage key does not indicate a
change already.

With this series, the kvm-unit-test "skey" now passes. \o/

v1 -> v2:
- "s390x/tcg: Rework MMU selection for instruction fetches"
-- Cleanup return value handling
- Added RB's

David Hildenbrand (6):
  s390x/mmu: ASC selection in s390_cpu_get_phys_page_debug()
  s390x/tcg: Rework MMU selection for instruction fetches
  s390x/tcg: Flush the TLB of all CPUs on SSKE and RRBE
  s390x/mmu: Trace the right value if setting/getting the storage key
    fails
  s390x/mmu: Better storage key reference and change bit handling
  s390x/mmu: Factor out storage key handling
