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.
