From 46b05d2617c8efd8ec6b19acd2c95541a0118c13 Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Wed, 21 Feb 2007 10:55:21 +0100 Subject: [S390] New header file ipl.h Setup.h has been misused for ipl related stuff in the past. We now move everything, which has to do with ipl and reipl to a new header file named "ipl.h".
