From: Michael Holzheu Date: Wed, 21 Feb 2007 09:55:21 +0000 (+0100) Subject: [S390] New header file ipl.h X-Git-Tag: v2.6.21-rc2~73 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=46b05d2617c8efd8ec6b19acd2c95541a0118c13;p=linux-2.6-omap-h63xx.git [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".
