Peter Maydell 1301becdab tcg: Support MMU protection regions smaller than TARGET_PAGE_SIZE ... Add support for MMU protection regions that are smaller than TARGET_PAGE_SIZE. We do this by marking the TLB entry for those pages with a flag TLB_RECHECK. This flag causes us to always take the slow-path for accesses. In the slow path we can then special case them to always call tlb_fill() again, so we have the correct information for the exact address being accessed. This change allows us to handle reading and writing from small regions; we cannot deal with execution from the small region.
