 *  -"/proc/meminfo | grep PageTables" kept on increasing
 *   Recently added pgtable dtor was not getting called.
 *
 * vineetg: May 2011
 *  -Variable pg-sz means that Page Tables could be variable sized themselves
 *    So calculate it based on addr traversal split [pgd-bits:pte-bits:xxx]
 *  -Page Table size capped to max 1 to save memory - hence verified.
 *  -Since these deal with constants, gcc compile-time optimizes them.
 *
 * vineetg: Nov 2010
 *  -Added pgtable ctor/dtor used for pgtable mem accounting
 *
 * vineetg: April 2010
 *  -Switched pgtable_t from being struct page * to unsigned long
 *      =Needed so that Page Table allocator (pte_alloc_one) is not forced to
 *       to deal with struct page. Thay way in future we can make it allocate
 *       multiple PG Tbls in one Page Frame
 *      =sweet side effect is avoiding calls to ugly page_address( ) from the
 *       pg-tlb allocator sub-sys (pte_alloc_one, ptr_free, pmd_populate
