  Modified files:
    sys/i386/isa         ipl.s 
    sys/i386/i386        trap.c 
  Log:
  - Change ast() to take a pointer to a trapframe like other architectures.
  - Don't use an atomic operation to update cnt.v_soft in ast().  This is
    the only place the variable is written to, and sched_lock is always
    held when it is written, so it is already protected and the mutex release
    of sched_lock asserts a memory barrier that ensures the value will be
    updated in a timely fashion.
