#     powerpc/mm/hash: Don't memset pgd table if not needed
#     
#     We need to zero-out pgd table only if we share the slab cache with
#     pud/pmd level caches. With the support of 4PB, we don't share the slab
#     cache anymore. Instead of removing the code completely hide it within
#     an #ifdef. We don't need to do this with any other page table level,
#     because they all allocate table of double the size and we take of
#     initializing the first half corrrectly during page table zap.
