For SMP it alloc 4kbyte * 64 interrupt * 32 cpu = 8Mbyte of ram. I' ll
find a way to alloc the memory only for running CPU soon. Now I am worried
about stability of the mechanism.
For UP the space alloced by the irq stack is 64kbyte so it doesn' t harm
at all.

I' d like to hear comments about this hack. I' d like if people would try
the patch in a SMP system too. But backup your HD before try it (should
not cause fs corruption but sure can lock your machine at any time)!
