jonathan 008816ea4f 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.

jonathan 1f44934407 * Change Sprite MACH_xxx prefix to MIPS_xxx.
* Use standard mips terminology (xxx_KSEG0, xxx_KSEG1) instead of the
  (more meaningful) Sprite names (xxx_CACHED, xxx_UNCACHED).

jonathan 68863ebd8e More mips1/mips3 changes to cpuregs.h and psl.h:
* 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.

jonathan 15628b2d97 Move merged pmax psl.h with mips1/mips3 support to mips/include/psl.h.
Change pmax/include/psl.h to just do #include <mips/psl.h>.

pmax/include/psl.h would go away completely if it wasn't stil required
by compat/common/kern_exit_43.c.
