Grant Likely 4c0946c474 irqdomain: eliminate slow-path revmap lookups ... With the current state of irq_domain, the reverse map is always updated when new IRQs get mapped. This means that the irq_find_mapping() function can be simplified to execute the revmap lookup functions unconditionally This patch adds lookup functions for the revmaps that don't yet have one and removes the slow path lookup code path. v8: Broke out unrelated changes into separate patches. Rebased on Paul's irq association patches. v7: Rebased to irqdomain/next for v3.4 and applied before the removal of 'hint' v6: Remove the slow path entirely. The only place where the slow path could get called is for a linear mapping if the hwirq number is larger than the linear revmap size. There shouldn't be any interrupt controllers that do that. v5: rewrite to not use a ->revmap() callback. It is simpler, smaller, safer and faster to open code each of the revmap lookups directly into irq_find_mapping() via a switch statement. v4: Fix build failure on incorrect variable reference.
