* 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.
closes PR port-i386/3751
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.
