#     powerpc/64s/radix: combine final TLB flush and lazy tlb mm shootdown IPIs
#     
#     This performs lazy tlb mm shootdown when doing the exit TLB flush when
#     all mm users go away and user mappings are removed, which avoids having
#     to do the lazy tlb mm shootdown IPIs on the final mmput when all kernel
#     references disappear.
#     
#     powerpc/64s uses a broadcast TLBIE for the exit TLB flush if remote CPUs
#     need to be invalidated (unless TLBIE is disabled), so this doesn't
#     necessarily save IPIs but it does avoid a broadcast TLBIE which is quite
#     expensive.
