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.
