commit 55601c9f (arm: omap: intc: switch over to linear irq domain) introduced a regression with SDMA legacy driver because that driver strictly depends on INTC's IRQs starting at NR_IRQs. Aparently irq_domain_add_linear() won't guarantee that, since we see a 7 IRQs difference when booting with and without the commit cited above. Until arch/arm/plat-omap/dma.c is properly fixed, we must maintain OMAP2/3 using irq_domain_add_legacy(). A FIXME note was added so people know to delete that code once that legacy DMA driver is fixed up.
