The genirq patch-queue improves the generic IRQ layer to be truly generic, by adding various abstractions and features to it, without impacting existing functionality. It converts ARM, i386 and x86_64 to this new generic IRQ layer - while keeping compatibility with all the other genirq architectures too. The full patch-queue can be downloaded from: http://redhat.com/~mingo/generic-irq-subsystem/ genirq -V5 is mostly about fixes and smaller cleanups. Suggestions from many people were included - let us know if anything is missing. It has been tested on i386, x86_64 and ARM systems. Changes since -V4: - fix: added IRQ_INPROGRESS protection to the fastack, level and simple flow handlers, to avoid irq reentry due to hardware bugs. (especially on SMP this is not unheard of.) - fix: fixed two old-style IRQ probing bugs on non-irqchip architectures. - fix: bad irq vectors should increase the IRQ kstat too - feature: added IRQ_DELAYED_DISABLE support for edge-irq handling on really dumb controllers. - docs: various documentation and comment updates - cleanup/speedup: cleaned up desc->depth and IRQ_DISABLED handling - the two were not always in sync. Made the generic flow handlers use IRQ_DISABLED instead of desc->depth - results in more optimal code. - cleanup: introduced generic_handle_irq(irq) for architectures to call when they want the generic layer to handle an interrupt. - rename: renamed probe_lock to probing_active - rename: renamed handle_level_irq_fastack to handle_fastack_irq - there is no strict requirement of the trigger type of the irq.
