Subject[PATCH v1 0/4] s390/kvm: fix MVPG when in VSIE
Date
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.

Claudio Imbrenda (4):
s390/kvm: VSIE: stop leaking host addresses
s390/kvm: extend guest_translate for MVPG interpretation
s390/kvm: add kvm_s390_vsie_mvpg_check needed for VSIE MVPG
s390/kvm: VSIE: correctly handle MVPG when in VSIE
