Subject: [PATCH 0/2] KVM: s390: interrupt: Fix stepping into interrupt handlers

Hi,

I tried to compare the behavior of KVM and TCG by diffing instruction
traces, and found two issues in KVM related to stepping into interrupt
handlers.

I'm not very familiar with the KVM code base, so please let me know if
the fixes can be improved or if these problems need to be handled
completely differently.

Best regards,
Ilya
