  SVN rev 208422 on 2010-05-22 21:38:57Z by neel
  
  - Use ptpgzone zone to allocate page table pages irrespective of the amount of
    memory on a platform. Tested on the Sibyte with 256MB and 1GB memory
    configurations.
  
  - Replace vtophys() with MIPS_KSEG0_TO_PHYS() to convert a page table
    page's virtual address to physical. We can safely do this because
    page table pages are allocated out of KSEG0.
  
  - Add an assertion to verify that when a page table page is freed it
    contains all zeroes. We can now use it after allocation without
    zeroing it.
