MIPS: TLB support for hugetlbfs.
The TLB handlers need to check for huge pages and give them special
handling. Huge pages consist of two contiguous sub-pages of physical
memory.
* Loading entrylo0 and entrylo1 need to be handled specially.
* The page mask must be set for huge pages and then restored after
writing the TLB entries.
* The PTE for huge pages resides in the PMD, we halt traversal of the
tables there.
