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.
