#     powerpc: Don't flush caches when adding memory
#     
#     This operation takes a significant amount of time when hotplugging
#     large amounts of memory (~50 seconds with 890GB of persistent memory).
#     
#     This was orignally in commit fb5924fddf9e
#     ("powerpc/mm: Flush cache on memory hot(un)plug") to support memtrace,
#     but the flush on add is not needed as it is flushed on remove.
