Several functions rely on the value of NR_IRQS to determine the maximum irq number that could get allocated. However, with sparse_irq and using irq_alloc_desc*() the maximum possible irq number is now specified with 'nr_irqs' which may be a number larger than NR_IRQS. This has caused breakage on powermac when CONFIG_NR_IRQS is set to 32. This patch removes most of the direct references to NR_IRQS in the powerpc code and replaces them with either a nr_irqs reference or by using the common for_each_irq_desc() macro. The powerpc-specific for_each_irq() macro is removed at the same time. Also, the Cell axon_msi driver is refactored to remove the global build assumption on the size of NR_IRQS and instead add a limit to the maximum irq number when calling irq_domain_add_nomap().
