Thomas Gleixner ab7798ffcf genirq: Expand generic show_interrupts()

Some archs want to print extra information for certain irq_chips which
is per irq and not per chip. Allow them to provide a chip callback to
print the chip name and the extra information.

PowerPC wants to print the LEVEL/EDGE type information. Make it configurable.

config SPARSE_IRQ bool "Support sparse irq numbering" depends on HAVE_SPARSE_IRQ ---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.
