Sukadev Bhattiprolu 0eab46be21 powerpc/mm: Add memory barrier in __hugepte_alloc() 
__hugepte_alloc() uses kmem_cache_zalloc() to allocate a zeroed PTE
and proceeds to use the newly allocated PTE. Add a memory barrier to
make sure that the other CPUs see a properly initialized PTE.

Based on a fix suggested by James Dykman.
