#     powerpc/64s/exception: KVM Fix for host DSI being taken in HPT guest MMU context
#     
#     Commit 2284ffea8f0c ("powerpc/64s/exception: Only test KVM in SRR
#     interrupts when PR KVM is supported") removed KVM guest tests from
#     interrupts that do not set HV=1, when PR-KVM is not configured.
#     
#     This is wrong for HV-KVM HPT guest MMIO emulation case which attempts
#     to load the faulting instruction word with MSR[DR]=1 and MSR[HV]=1 with
#     the guest MMU context loaded. This can cause host DSI, DSLB interrupts
#     which must test for KVM guest. Restore this and add a comment.
#     
#     Fixes: 2284ffea8f0c ("powerpc/64s/exception: Only test KVM in SRR interrupts when PR KVM is supported")
