Modified Files: src/sys/kern: kern_runq.c src/sys/sys: sched.h Log Message: - Another tweak for SMT: if a new LWP is starting life, try to make it run on a different CPU in the same CPU core as the parent, because both parent and child share lots of state. (I want to come back later and do something different for _lwp_create() and maybe execve().) - Remove the runqueue evcnts, which are racy and impose a penalty for very little payoff. - Break out of the loop in sched_takecpu() as soon as we have a CPU that can run the LWP. There's no need to look at all CPUs. - SPCF_IDLE in sched_enqueue() so we know the CPU is not idle sooner.
