Subject: [PATCH v2 0/2] s390/kvm: VSIE: fix prefixing and MSO for MVPG
Date: Mon, 22 Mar 2021 15:05:57 +0100 [thread overview]
Message-ID: <20210322140559.500716-1-imbrenda@linux.ibm.com> (raw)
The guest real address needs to pass through prefixing in order to yield
the absolute address.
The absolute address needs to be offset by the MSO in order to get the
host virtual address.
v1->v2
* use the MSO from the shadow SIE page instead of the original one
* reuse src and dest variabled to improve readability
