genirq: Add new IPI irqdomain flags
These flags will be used to identify an IPI domain. We have two flavours of IPI implementations: IRQ_DOMAIN_FLAG_IPI_PER_CPU: Each CPU has its own virq and hwirq IRQ_DOMAIN_FLAG_IPI_SINGLE : A single virq and hwirq for all CPUs Signed-off-by: Qais Yousef <qais.yousef@imgtec.com> Cc: <jason@lakedaemon.net> Cc: <marc.zyngier@arm.com> Cc: <jiang.liu@linux.intel.com> Cc: <ralf@linux-mips.org> Cc: <linux-mips@linux-mips.org> Cc: <lisa.parratt@imgtec.com> Cc: Qais Yousef <qsyousef@gmail.com> Link: http://lkml.kernel.org/r/1449580830-23652-2-git-send-email-qais.yousef@imgtec.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
