Update of /cvsroot/src/sys/arch/powerpc/powerpc
In directory netbsd1:/var/slash-tmp/cvs-serv11203

Modified Files:
        machdep.c 
Log Message:
Several changes from Wolfgang Solfrank, Charles Hannum, and myself:
- Make setregs() conform to the PowerPC SVR4 ABI, plus one NetBSD
  extention (for ps_strings).
- machine == powerpc, not PowerPC.
- Set up machine vector for OpenFirmware.
- Nuke the msgbuf for now; it's not mapped correctly.
- Add missing casts in some asm() directives.
- Enable PSL_RI earlier, and do *not* disable it in fake_spl(), since it
  is needed for page faults.
- Some general cleanup.
