Tiejun,

I'm a little confused by these patches, because the actual critical
exception handlers are still commented out:

/* Critical Input Interrupt */
        START_EXCEPTION(critical_input);
        CRIT_EXCEPTION_PROLOG(0x100, BOOKE_INTERRUPT_CRITICAL,
                              PROLOG_ADDITION_NONE)
//      EXCEPTION_COMMON(0x100, PACA_EXCRIT, INTS_DISABLE)
//      bl      special_reg_save_crit
//      CHECK_NAPPING();
//      addi    r3,r1,STACK_FRAME_OVERHEAD
//      bl      .critical_exception
//      b       ret_from_crit_except
        b       .

Are you working on fixing this?  I'm trying to fix it, too, but I
think you're way ahead of me.
