  Modified files:
    sys/alpha/alpha      trap.c 
    sys/i386/i386        trap.c 
    sys/ia64/ia64        trap.c 
  Log:
  - Grab the proc lock around CURSIG and postsig().  Don't release the proc
    lock until after grabbing the sched_lock to avoid CURSIG racing with
    psignal.
  - Don't grab Giant for addupc_task() as it isn't needed.
  
  Reported by:	tegge (signal race), bde (addupc_task a while back)
