From d1d8c666683cdbef18329ff8f3743ddaca8842ee Mon Sep 17 00:00:00 2001 From: Colin Cross Date: Sun, 1 May 2011 15:26:51 -0700 Subject: ARM: tegra: irq: Move legacy_irq.c into irq.c Now that irq.c is just an interface layer between the gic and legacy_irq.c, move the contents of legacy_irq.c into irq.c.
