From cbdc229245e8cf5c201e68221ebf2f33d2aaf029 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Thu, 26 Mar 2009 15:23:52 +0100 Subject: [PATCH] [S390] arch/s390/kernel/process.c: fix whitespace damage Fix all the whitespace damage in process.c, especially copy_thread(). Next patch will add code to copy_thread() which needs to 'fixed' first.
