Well, the SH5 pmap actually works a lot like a PowerPC 603 pmap, if I
understand it correctly.  Note that the use of the term "KSEG" in the
SH5 pmap is not the same as "KSEG" in the MIPS world.  In SH5-land, it's
just a convenient way to refer to some special regions that are mapped
*with the TLB*.
