Paul Burton 091bc3a404 MIPS: tlb-r4k: panic if the MMU doesn't support PAGE_SIZE
After writing the appropriate mask to the cop0 PageMask register, read
the register back & check it matches what we want. If it doesn't then
the MMU does not support the page size the kernel is configured for and
we're better off bailing than continuing to do odd things with TLB
exceptions.
