What: __do_IRQ all in one fits nothing interrupt handler
When: 2.6.32
Why: __do_IRQ was kept for easy migration to the type flow handlers.
More than two years of migration time is enough.

This enables support for sparse irqs. This is useful for distro
kernels that want to define a high CONFIG_NR_CPUS value but still
want to have low kernel memory footprint on smaller machines.
( Sparse IRQs can also be beneficial on NUMA boxes, as they spread
out the irq_desc[] array in a more NUMA-friendly way. )
If you don't know what to do here, say N.
