From e86a6ed63f46fe8fb555fda531084bca3ef62fd7 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Fri, 11 Sep 2009 10:29:04 +0200 Subject: [PATCH] [S390] Get rid of cpuid.h header file. Merge cpuid.h header file into cpu.h. While at it convert from typedef to struct declaration and also convert cio code to use proper lowcore structure instead of casts.
