From 9163bb2e556f6c7879961df94540f0879db4717b Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Mon, 4 Dec 2006 15:40:59 +0100 Subject: [S390] non-unique constant/macro identifiers. Add some prefixes to constands defined in drivers/s390/net/qdio.h and drivers/s390/lcs.h to make it possible to include the three header files drivers/s390/net/qeth.h, drivers/s390/net/qdio.h and drivers/net/s390/lcs.h in one C file. This is required for the patch that generates the kerntypes.o file for use by lcrash.
