This series fixes 2 small bugs introduced with asynchronous teardown. The first patch (unmodified since v1, but did not get any reviews) fixes a potential race that can cause crashes during shutdown on machines that don't support protected virtualization. The second patch adds a missing initialization when replacing the ASCE for a protected guest. This could potentially cause issues and crashes if lowcore is affected. v1->v2: * added the second patch Claudio Imbrenda (2): KVM: s390: pv: simplify shutdown and fix race KVM: s390: pv: fix index value of replaced ASCE arch/s390/kvm/pv.c | 8 ++++++-- arch/s390/mm/gmap.c | 1 + 2 files changed, 7 insertions(+), 2 deletions(-)
