genirq: Provide Kconfig The generic irq Kconfig options are copied around all archs. Provide a generic Kconfig file which can be included.

genirq: Provide config option to disable deprecated code This option covers now the old chip functions and the irq_desc data fields which are moving to struct irq_data. More stuff will follow. Pretty handy for testing a conversion, whether something broke or not. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Reviewed-by: Ingo Molnar <mingo@elte.hu>

genirq: Add IRQ_INPROGRESS to core We need to maintain the flag for now in both fields status and istate. Add a CONFIG_GENERIC_HARDIRQS_NO_COMPAT switch to allow testing w/o the status one. Wrap the access to status IRQ_INPROGRESS in a inline which can be turned of with CONFIG_GENERIC_HARDIRQS_NO_COMPAT along with the define. There is no reason that anything outside of core looks at this. That needs some modifications, but we'll get there. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

genirq: Implement generic irq_show_interrupts() All archs implement show_interrupts() in more or less the same way. That's tons of duplicated code with different bugs with no value. Implement a generic version and deprecate show_interrupts() Unfortunately we need some ifdeffery for !GENERIC_HARDIRQ archs. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

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.
