  Modified files:
    sys/i386/i386        trap.c 
  Log:
  Fix some problems for cpu_switch_load_gs. when fault address is at
  cpu_switch_load_gs, cpu is in context switch, so don't enable interrupt.
  because it is in context switch, it is expected sched_lock was held,
  so don't PROC_LOCK(p) and psignal, it is LOR, probably we can
  set a P_XSIGBUS like flag in p_sflags, and set TDF_ASTPENDING in
  td_flags, in ast(), post a SIGBUS to process if P_XSIGBUS was set.
