irq_domain/mips: Allow irq_domain on MIPS
This patch makes IRQ_DOMAIN usable on MIPS. It uses an ugly workaround to preserve current behaviour so that MIPS has time to add irq_domain registration to the irq controller drivers. The workaround will be removed in Linux v3.6 Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: linux-mips@linux-mips.org
