eb71a02a7f Re-write of CPU/MMU detection code. 
Use a table driven classification based on CPU and MMU implementation/version
fields. Each CPU class or module defines a collection of routines that
implement CPU or MMU specific operations that can collect detailed setup
information.

All information is collected in a `cpu_softc' structure provided by the
auto-configuration code. However, in the interest of SMP support this
structure is located at a fixed virtual address identified by the
symbol `cpuinfo'. The `boot' CPU currently uses the the physical page(s) at
address 0x2000 for its cpuinfo. Consequently, the fixed virtual address
will be `KERNBASE+0x2000'.

The cache flush routines for several systems (sun4/4c vs. sun4m;
virtual vs. physical tags) have been factored out. Function pointers
to an appropriate set are located in `cpuinfo'. The former global
`cacheinfo' structure is now also a part of `cpuinfo'. Because of the
fixed virtual address of `cpuinfo' no extra performance penalties
are incurred by this move. In multi-architecture kernels, there's
no longer the need for run-time `cputyp' tests in this part of the system.

pk
8d2c03c810 Replace `cputyp' run-time tests by inserting multiple branches and NOPing 
some at startup depending on architecture.

Use `get_faultstatus' field in `cpuinfo' (initialized in cpu.c) to branch
to CPU/MMU specific fault status reading stubs on memory fault traps.

Remove code top map the Interrupt Enable register on sun4/sun4c. Its VA
has moved to a high location and is now mapped in autoconf.c after
pmap has initialized. Note: this renders NMIs during bootstrap() fatal
(maybe loading %tbr should be deferred).

4ca0768334 Fix bug in pmap_page_copy and pmap_page_zero that caused data corruption 
when paging on Sun4m machines with SuperSPARC processors. Essentially,
the copy/zero operations were done via uncached memory accesses, which
bypassed the snooping logic of the write-back caches, causing stale data
to be copied or generated.
