From dc6e15556a9f21d640a62ae6de3cbfa68ec687a4 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 12 Oct 2015 13:00:39 +0200 Subject: s390/nmi: remove casts Remove all the casts to and from the machine check interruption code. This patch changes struct mci to a union, which contains an anonymous structure with the already known bits and in addition an unsigned long field, which contains the raw machine check interruption code. This allows to simply assign and decoce the interruption code value without the need for all those casts we had all the time.
