Prev: [GITPULL+PATCH 0/2 v3] irq: move some interrupt arch_* functions into struct irq_chip.
Next: [patch] acpi_pad: "processor_aggregator" name too long
From: Ian Campbell on 19 Mar 2010 07:30
arch_early_irq_init ensures that in the non-SPARSE_IRQ case that
chip_data is only set for irq < NR_IRQS which means that the
SPARSE_IRQ version of irq_cfg behaves exactly the same as the
non-SPARSE_IRQ version when SPARSE_IRQ is disabled.
