#     powerpc/mce: Fix SLB rebolting during MCE recovery path.
#     
#     The commit e7e81847478 ("powerpc/64s: move machine check SLB flushing
#     to mm/slb.c") introduced a bug in reloading bolted SLB entries. Unused
#     bolted entries are stored with .esid=0 in the slb_shadow area, and
#     that value is now used directly as the RB input to slbmte, which means
#     the RB[52:63] index field is set to 0, which causes SLB entry 0 to be
#     cleared.
#     
#     Fix this by storing the index bits in the unused bolted entries, which
#     directs the slbmte to the right place.
#     
#     The SLB shadow area is also used by the hypervisor, but PAPR is okay
#     with that, from LoPAPR v1.1, 14.11.1.3 SLB Shadow Buffer:
#     
#       Note: SLB is filled sequentially starting at index 0
#       from the shadow buffer ignoring the contents of
#       RB field bits 52-63
#     
#     Fixes: e7e81847478b ("powerpc/64s: move machine check SLB flushing to mm/slb.c")
