Ingo said, I only need to work on tip/master, and you guys will sort it out.
Eric's NR_IRQS patch for 2.6.27 is not in tip yet. --- Andrew picked up already

maybe i need put eric's patch before alan's patch in next sending...

will check it. it could be just replace irq_desc[] to irq_desc()...

another reason: dyn_arry == static in some case, so I could make sure
compiling work well between static/dyn_array with sparse_irq.
