It may well be that interrupt stacks are a win anyway. If we can get the kernel struct out of the stack pages (which would fix some very unpleasant cache colour problems) and take the non irq stack down to 4K then irq stacks would pay off once you had 25 or so processes on a system - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
