config SPARSE_IRQ
bool "Support sparse irq numbering"
depends on EXPERIMENTAL
help
This enables support for sparse irqs. This is useful in general
as most CPUs have a fairly sparse array of IRQ vectors, which
the irq_desc then maps directly on to. Systems with a high
number of off-chip IRQs will want to treat this as
experimental until they have been independently verified.
If you don't know what to do here, say N.
