[PATCH 30/38] KVM: PPC: bookehv: add comment about shadow_msr

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

For BookE HV the guest visible MSR is shared->msr and is identical to
the MSR that is in use while the guest is running, because we can't trap
reads from/to MSR.

So shadow_msr is unused there. Indicate that with a comment.
