735 help 736 This enables support for sparse irqs. This is useful in general 737 as most CPUs have a fairly sparse array of IRQ vectors, which 738 the irq_desc then maps directly on to. Systems with a high 739 number of off-chip IRQs will want to treat this as 740 experimental until they have been independently verified. 741 742 If you don't know what to do here, say N. --- 133 unchanged lines hidden --- | 734 help 735 This enables support for sparse irqs.
