mappings to a user pmap when it's created rather than at context
allocation time. Also, do not copy the kernel's region administration

to copy it into.
As a result of this, we must now switch to context 0 in both pmap_copy_page()

Replace many setpte4m() calls with a simpler helper function because
...
the address of the desired PTE location is readily available in the
callers context (setpte4m() retraces the entire 3-level structure
to arrive at the PTE location).
Also, in many cases we can do away with the distinction between pmaps
that have or have not allocated a context. This is really only useful
in cases where we're interested in the REF or MOD bits which can differ
in the TLB version of a PTE. By doing this, we avoid getpte()'s which
in many cases instruct the MMU to start a table walk only to find out
that there's nothing there after going 2/3 of the way, or waste a TLB
entry because of TLB flushing soon after getpte() completes.
In addition, there's a hook to flush the cache line corresponding to
the (kernel virtual) location of a PTE entry when it gets altered.

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.

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).
