#     powerpc/mm/hash/4k: Free hugetlb page table caches correctly.
#     
#     With 4k page size for hugetlb we allocate hugepage directories from its on slab
#     cache. With patch 0c4d26802 ("powerpc/book3s64/mm: Simplify the rcu callback for page table free")
#     we missed to free these allocated hugepd tables.
#     
#     Update pgtable_free to handle hugetlb hugepd directory table.
#     
#     Fixes:  0c4d26802 ("powerpc/book3s64/mm: Simplify the rcu callback for page table free")
