Nitin Gupta 7bc3777ca1 sparc64: Trim page tables for 8M hugepages ... For PMD aligned (8M) hugepages, we currently allocate all four page table levels which is wasteful. We now allocate till PMD level only which saves memory usage from page tables. Also, when freeing page table for 8M hugepage backed region, make sure we don't try to access non-existent PTE level.
