* cpuregs.h:
rename remaining VMMACH_xxx TLB macros to MIPS_TLB_xxx.
Add compile-time MIPS3-only, compile-time MIPS1-only, and
runtime (both) definitions for number of TLB ASIDs (tlb pids)
and shift count to extract a TLB pid.
* locore.h:
Delete unused vector slot for indexed TLB writes.
mips1 and mips3 TLBs are different enough that we have
to break them out at the caller anyway.
* Add compile-time MIPS3-only andcompile-time MIPS1-only
macros to call locore functions directly by name.
Use the existing method table only if
* mips/mips_machdep.c, mips/trap.c, mips/pmap.c, pmax/machdep.c:
Use MIPS3_ or MIPS1_ specific names for TLB pids in
mips3 and mips1 specific code paths (e.g., creating the kernel stack
for process 0).
Add `options MIPS3' to pmax/conf/GENERIC.
Remove unused debug procedure I forgot to remove previously.
Consolidate the vm_page_free1() calls in pmap_release(). Duplicate code
was a result of the way I merged the MIPS3 support from the pica pmap.c.
Enhance the comment on flushing the cache when releasing the segmap pages,
and add a comment about the currently unused code to uncache pages in
pmap_enter_pv().
unsigned cause register wouldn't have worked.
Add missing ')' in trapdump that shows up when compiled with DEBUG.
Fix (unfix?) previous change to printf formats in mips3_dump_tlb: vad_to_pfn
is now consistant with single-CPU and merged-CPU support.
* cpuregs.h:
Delete unused VMMACH_ names (e.g., duplicates of PTE bits in pte.h).
Change remaining VMMACH_xxx names to MIPS1_xxx or MIPS3_xx.
Fold remaining compile-time definitions into a single #ifdef MIPS3.
* Use MIPS1_ names in locore_r2000.S, mips3_ names in locore_r4000.S
* Garbage-collect MachHitFlushDCache()
* psl.h:
use MIPS1_, MIPS3_ symbolic names for Cause register bits.
change _R3K to MIPS1_, _R4K to MIPS3. Conditionalize for mips1 only,
mips3 only, or when both are defined, use runtime CPUISMIPS3 test.
now be installed on any partition.
Allow PRIM_LOADSZ to be set in the Makefile.
This together allows to make bootable 720k floppys.

Remove cpu-specific routines from locore.S and add them to locore_r2000.S
and locore_r4000.S. Add entries in locore jump vector table for switch_exit()
and the cpu_switch() context resume.
Add offsets into the jump vector to genassym.cf for use in locore.S.

Use same cachesize variables for mips1 and mips3, and rename the variables
per Jonathan's request.
the stack frame when usermode interrupt occurs. The interrupt may have
modified the PC [such as sendsig()]. This got dropped with the stackframe
changes.
