New MIPS cache primitives and code to configure which ones are used.
New style cache operations for R2000/R3000-style caches.
New style cache operations for R4000/R4400-style caches.
New style cache operations for R4600/R5000-style caches.
New style cache operations for TX39-style caches.  XXX This is not
yet complete.
Adapt to new cache code.  bus_dmamap_sync() is now optimized for
virtually-indexed write-back caches.
Update for the new cache code.  bus_dmamap_sync is now optimized
for a virtually-indexed, write-back cache.
Pull in new cache code, conditional on which CPU arch's are configured
into the kernel.
Update for the new cache code.  Some careful code review is needed
here, esp. by people who have done recent MIPS pmap hacking.
Update for the new cache code.  There are now two optimized
bus_dmamap_sync routines: one for a physically-indexed write-through
cache, and one for a virtually-indexed write-back cache.
