Paul Mundt 2277ab4a1d sh: Migrate from PG_mapped to PG_dcache_dirty. ... This inverts the delayed dcache flush a bit to be more in line with other platforms. At the same time this also gives us the ability to do some more optimizations and cleanup. Now that the update_mmu_cache() callsite only tests for the bit, the implementation can gradually be split out and made generic, rather than relying on special implementations for each of the peculiar CPU types. SH7705 in 32kB mode and SH-4 still need slightly different handling, but this is something that can remain isolated in the varying page copy/clear routines. On top of that, SH-X3 is dcache coherent, so there is no need to bother with any of these tests in the PTEAEX version of update_mmu_cache(), so we kill that off too.
