Commit "ARM: gic: add irq_domain support" (b49b6ff) breaks SPARSE_IRQ on platforms with GIC. When SPARSE_IRQ is enabled, all NR_IRQS or mach_desc->nr_irqs will be allocated by arch_probe_nr_irqs(). This caused irq_alloc_descs to allocate irq_descs after the pre-allocated space. Make irq_alloc_descs search for an exact irq range and assume it has been pre-allocated on failure. For DT probing dynamic allocation is used. DT enabled platforms should set their nr_irqs to NR_IRQ_LEGACY and have all irq_chips allocate their irq_descs with irq_alloc_descs if SPARSE_IRQ is enabled. gic_init irq_start param is changed to be signed with negative meaning do dynamic Linux irq assigment.
