  Micro caches don't work in 4k pages, so what has this to do with
anything? I suspect you're thinking of mainframe cache which may work
in larger chunks. 4, 16, and 32 byte cache chunks are mentioned by
manufacturers, I think someone used 64 bytes, but I haven't got the
name.

  If anyone has an Intel cache controller spec sheet handy, please
contribute.
