From 90a6646bf6a1ca821f32d5510e935855612904df Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 8 Mar 2006 17:18:19 -0800 Subject: [PATCH] [SPARC64]: Fix system type in /proc/cpuinfo and remove bogus OBP check. Report 'sun4v' when appropriate in /proc/cpuinfo Remove all the verifications of the OBP version string. Just make sure it's there, and report it raw in the bootup logs and via /proc/cpuinfo.
