725 Enabling this option will allow the kernel to implement some
726 atomic operations using a software implementation of load-locked/
727 store-conditional (LLSC). On machines which do not have hardware
728 LLSC, this should be more efficient than the other alternative of
729 disabling interrupts around the atomic sequence.

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.

742 If you don't know what to do here, say N.
