b67b90d7f9 FPA ownership is now guarded by MDP_FPUSED flag and there is no necessity 
to have #if ... around savefpregs() calls.

0e501989cd - Have savefpregs() and loadfpregs() in C codes with lengthy inlined 
asm statements, obsoluting asm routines in locore.S.  They are
  designed to work in symmetry as names suggests.  savefpregs()
  does not clear a global variable fpcurproc.  Both would be noops when
  NOFPU global symbol is defined.
- MDP_FPUSED flag is not turned on for FPA-less processors like Vr4100
  and TX3900 even when processes execute FP insns.

992002c2be Use the cpu_info struct to store cpu-specific data in the same way in 
both uniprocessor and multiprocessor environments. Use the otherwise
unused internal CPU register SSP to store the cpu_info pointer.
The macros curcpu(), curproc, cpu_number() and need_resched() are now the
same in both uniprocessor and multiprocessor environments.

8e19d02f25 Cleanup take two 
- Nuke external function reference of savefpregs() which is already defined
  in mips/cpu.h.
- Adjust the comment tells "let user processes change CP0 status register
  freely might be dangerous."

3f8e9c25b6 Make claried MDP_FPUSED usage. 
- MDP_FPUSED flag indicates the process has executed at least one
  FP insn during its life time.
- pcb_fpregs storage is guaranteed zero initialzed.  If the process is FPA
  owner, savefpregs() must be called to synchronize it with FPA contents.
- No necessity to save FPA contents into pcb_fpregs prior to the whole
  storage is overwritten by process_write_fpregs().

SIMMS the memory size was configured at 128MB instead of 32MB.

e03e9e8086 Rather than starting init and creating kthreads by forking and then 
doing a cpu_set_kpc(), just pass the entry point and argument all
the way down the fork path starting with fork1().  In order to
avoid special-casing the normal fork in every cpu_fork(), MI code
passes down child_return() and the child process pointer explicitly.

This fixes a race condition on multiprocessor systems; a CPU could
grab the newly created processes (which has been placed on a run queue)
before cpu_set_kpc() would be performed.
