This patch removes the simplistic implementation of irq_domains and enables the powerpc infrastructure for all irq_domain users. The powerpc infrastructure includes support for complex mappings between Linux and hardware irq numbers, and can manage allocation of irq_descs. This patch also converts the few users of irq_domain_add()/irq_domain_del() to call irq_domain_add_legacy() instead. v3: Fix bug that set up too many irqs in translation range. v2: Fix removal of irq_alloc_descs() call in gic driver Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: Olof Johansson <olof@lixom.net>
