From 9c77047a55a3f0d3168071812227209a5641ed05 Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 22 Nov 2011 14:47:04 +0000 Subject: [PATCH] MIPS: Octeon: Update feature test functions for new chips and features. cvmx.h was rearranged to fix include file ordering problems, but there is no change other than moving some definitions around.
