From 3de620e8394406fd01f450b8c6e3e74464e81a78 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Wed, 10 May 2006 13:05:54 +1000 Subject: [PATCH] powerpc: fix kernel version display on pseries boxes We are displaying the wrong thing on the operator panel (2x40 character LCD). This got broken in commit cebb21b5, when UTS_RELEASE got changed to system_utsname.version.
