#     powerpc/mm/32: Fix pgtable_page_dtor call
#     
#     Commit 667416f38554 ("powerpc/mm: Fix kernel crash on page table free")
#     added a call for pgtable_page_dtor in the rcu page table free routine. We missed
#     the fact that for 32 bit platforms we did call the 'dtor' early. Drop the extra
#     call for pgtable_page_dtor. We remove the call from __pte_free_tlb so that we
#     do the page table free and 'dtor' call together. This should help when we
#     switch these platforms to pte fragments.
#
