From mboxrd@z Thu Jan 1 00:00:00 1970 From: Aaron Young Date: Wed, 28 Jun 2006 15:34:55 +0000 Subject: [PATCH] RESEND - fix prom revision checks in SN kernel Message-Id: <200606281534.IAA17348@google.engr.sgi.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org (Resend #1 - patch is now based off the aegl/linux-2.6.git tree) The following patch fixes a few spots in the SN kernel that check a fixed prom revision number to determine prom feature support. These checks are only valid on shub1 systems. They are invalid on shub2 systems which have a different prom with different revision numbers.
