From 96f339c6b95344942fe5fce012ff4f2a3b2cb80d Mon Sep 17 00:00:00 2001 From: Greg Edwards Date: Wed, 28 Sep 2005 17:05:19 -0500 Subject: [PATCH] [IA64] mbcs_init() should give up unless running on sn2 CONFIG_SGI_MBCS is enabled in generic kernels, but the driver may oops some other platforms. Check whether we are running on sn2 and bail out if we are not before doing anything dangerous.
