Define the conventional pmax locore entry-point names to be calls through an vector (struct) of function pointers. Add prototype declarations for each vector entry. Add declarations for the r2000 (MIPS-I) and r4000 (MIPS-III) locore versions of the relevant functions.

Changes to sys/arch/mips from ARC port, from Noriyuki Soda <soda@sra.co.jp>. Adds (most) support for ARC platform to port-independent mips code. Some changes (e.g., clean up of overlapping CPU/FPU ids) inspired by comparison to the OpenBSD 2.1 codebase of Soda's ARC port. Open issues: * Still no support for r4600 or mipsIV CPUs with two-way L1 cache. Code derived from Per Fogelstrom's OpenBSD source doesn't work on mips3 pmaxes with L2 cache. * Still some port-specific #ifdefs, for interrupt enable and pmax L2 cache-size. Needs more thought, but overlaps with work-in-progress by Tohru and Tsubai on spl()s and related stuff.

Final changes for configuring MIPS1 and MIPS3 in a single kernel. * 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.

Changes to sys/arch/mips from ARC port, from Noriyuki Soda <soda@sra.co.jp>. Adds (most) support for ARC platform to port-independent mips code. Some changes (e.g., clean up of overlapping CPU/FPU ids) inspired by comparison to the OpenBSD 2.1 codebase of Soda's ARC port. Open issues: * Still no support for r4600 or mipsIV CPUs with two-way L1 cache. Code derived from Per Fogelstrom's OpenBSD source doesn't work on mips3 pmaxes with L2 cache. * Still some port-specific #ifdefs, for interrupt enable and pmax L2 cache-size. Needs more thought, but overlaps with work-in-progress by Tohru and Tsubai on spl()s and related stuff.

Changes for configuring both MIPS1 and MIPS3, from a merge of similar design and code by Jason Thorpe and Jonathan Stone. NOTE: the kernel-stack-switching code and cacheflush() calls in locore.S still use #ifdef MIPS3 and need more work. mips/include/cpu.h: Add CPUISMIPS3 for run-time tests of what CPU architecture level we're running on. mips/include/locore.h: Add declarations of locore cache-size variables for ref/def toolchain. mips/include/mips1_pte.h: mips1 TLB bit definitions. mips/include/mips3_pte.h: mips3 TLB bit definitions. mips/include/pte.h: define accesor macros for TLB bits (e.g., mips_pg_m_bit(), that expand to CPU constants if only one CPU arch is configured, or to inline functions if both MIPS1 and MIPS3 are configured. mips/mips/locore_r2000.S: Use MIPS1_PG_xxx constants inside mips1-specific code. mips/mips/locore_r4000.S: Use MIPS3_PG_xxx constants inside mips3-specific code. mips/mips/locore.S: Use MIPS1_PG_xxx constants inside mips3-specific code. Use MIPS1_PG_xxx constants inside mips1-specific code. (Needs more work!) mips/mips/{pmap.c,vm_machdep.c,trap.c}, pmax/pmax/machdep.c: Use MIPS3_PG_xxx constants inside mips3-specific functions, and MIPS1_PG_XXX inside mips1-specific code. Otherwise, use mips_pg_XXX_bit() macros where they apply, and use "if (CPUISMIPS3) { ... } else {... }" where they don't. mips/mips/mips_machdep.c: Import Michael Hitch's fixes from the pmax locore-init code into mips_vector_init(). pmax/pmax/machdep.c: Use generic mips_vector_init() locore vector-init function.
