The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

+ ---help---
+
+ Sparse irq numbering 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 interrupt descriptors in a more NUMA-friendly way. )
+
+ If you don't know what to do here, say N.
