#     Revert "powerpc/powernv: Increase memory block size to 1GB on radix"
#     
#     This commit was a stop-gap to prevent crashes on hotunplug, caused by
#     the mismatch between the 1G mappings used for the linear mapping and the
#     memory block size. Those issues are now resolved because we split the
#     linear mapping at hotunplug time if necessary, as implemented in commit
#     4dd5f8a99e79 ("powerpc/mm/radix: Split linear mapping on hot-unplug").
