From 1dad093b66fdd4fd5d7d2692169dc1bafd794628 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Mon, 31 Mar 2014 15:24:08 +0200 Subject: s390/irq: Use defines for external interruption codes Use the new defines for external interruption codes to get rid of "magic" numbers in the s390 source code. And while we're at it, also rename the (un-)register_external_interrupt function to something shorter so that this patch does not exceed the 80 columns all over the place.
