[PATCH v2 0/2] s390/kvm: fix MVPG when in VSIE

[Claudio Imbrenda]

The current handling of the MVPG instruction when executed in a nested
guest is wrong, and can lead to the nested guest hanging.

This patchset fixes the behaviour to be more architecturally correct,
and fixes the hangs observed.

v1->v2
* complete rewrite

Claudio Imbrenda (2):
  s390/kvm: extend kvm_s390_shadow_fault to return entry pointer
  s390/kvm: VSIE: correctly handle MVPG when in VSIE
