#     powerpc/64s/powernv: Fix memory corruption when saving SLB entries on MCE
#     
#     This can be hit by an HPT guest running on an HPT host and bring down
#     the host, so it's quite important to fix.
#     
#     Fixes: 7290f3b3d3e6 ("powerpc/64s/powernv: machine check dump SLB contents")
