From 9b56febea22003c424f11248908b534eba0f1eeb Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 28 Mar 2013 12:57:40 +0000 Subject: ARM: entry: move IRQ tracing exit into svc_exit The IRQ tracing exit path is much the same between all SVC mode exits, so move this into the svc_exit macro. Use a macro parameter to identify the IRQ case, which is the only different case there is.
