#     powerpc/mm: Fixup tlbie vs store ordering issue on POWER9
#     
#     On POWER9, under some circumstances, a broadcast TLB invalidation
#     might complete before all previous stores have drained, potentially
#     allowing stale stores from becoming visible after the invalidation.
#     This works around it by doubling up those TLB invalidations which was
#     verified by HW to be sufficient to close the risk window.
#     
#     This will be documented in a yet-to-be-published errata.
#     
#     Fixes: 1a472c9dba6b ("powerpc/mm/radix: Add tlbflush routines")

#     [mpe: Enable the feature in the DT CPU features code for all Power9,
#           rename the feature to CPU_FTR_P9_TLBIE_BUG per benh.]

The function .stop_machine_change_mapping() references

This is often because .stop_machine_change_mapping lacks a __meminit
