From 394edb5af5161f664c0c3b4eaba9be4e30f3c138 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Fri, 5 Apr 2013 23:59:52 -0700 Subject: [PATCH] intel: Require kernel 2.6.39 for relaxed relocation support. Chris Wilson's relaxed relocation patch landed in March 2011. Anyone running pre-3.0 kernels probably isn't going to get the latest Mesa anyway.
