Log Message:
Pull up following revision(s) (requested by martin in ticket #799):
sys/arch/mips/include/locore.h: revision 1.79
sys/arch/mips/mips/locore_mips1.S: revision 1.65
sys/arch/mips/mips/mipsX_subr.S: revision 1.28
sys/arch/mips/mips/mips_machdep.c: revision 1.211
sys/arch/mips/mips/vm_machdep.c: revision 1.123
Do not use the same trampoline for cpu_lwp_fork and cpu_setfunc - only
the former needs to call lwp_startup().
