this series adds mapping color control to the generic kmap code, allowing

I haven't actually ported this to MIPS but it certainly appears to be
the right framework to get highmem aliases handled on MIPS, too.

Though I still consider increasing PAGE_SIZE to 16k the preferable
solution because it will entirly do away with cache aliases.

Thanks,
