Hi Libra Li,

Thanks for making these changes. I like the idea of the mainboard
interrupt function. I have a few comments.

+typedef struct {
+        int mask[256];
+        int (*intXX_handler[256])(struct eregs *regs);

This is a really big structure and probably not needed. I don't think
anyone would override every interrupt vector, just one or two like you
are doing. Maybe just use a table that has the interrupt and function

+	if(!(*intXX_handler))
+	{
+		/* Set up C interrupt handlers */
+		setup_interrupt_handlers();
+	}

Is this because mainboard_interrupt_handlers gets called first and the
interrupts are over written? It would be better if the defaults could
always be loaded and then the main board interrupts get fixed up.
