Subject: [PATCH 0/4] KVM: s390: Fix minor bugs in STFLE shadowing
Date: Fri, 3 Nov 2023 18:30:04 +0100 [thread overview]
Message-ID: <20231103173008.630217-1-nsg@linux.ibm.com> (raw)
Fix two bugs in the STFLE vsie implementation.
The first concerns the identification if the guest is intending
to use interpretive execution for STFLE for its guest.
The second fixes too much of the guests memory being accessed when
shadowing.
