From mboxrd@z Thu Jan 1 00:00:00 1970 From: edwardsg@sgi.com (Greg Edwards) Date: Mon, 26 Apr 2004 18:42:50 +0000 Subject: [PATCH] Remove SN PDA page overflow check Message-Id: <20040426184250.GH5165@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 There's an obsolete check in sn_init_pdas() left over from the 2.4 days that panics if the cpu PDA and cpu_data area span more than a page. With 2.6, we're not limited to a page, so remove the check entirely. Patch against linux-2.5 bk.
