From 2ef9481e666b4654159ac9f847e6963809e3c470 Mon Sep 17 00:00:00 2001 From: Jon Mason Date: Mon, 23 Jan 2006 10:58:20 -0600 Subject: [PATCH] powerpc: trivial: modify comments to refer to new location of files This patch removes all self references and fixes references to files in the now defunct arch/ppc64 tree. I think this accomplises everything wanted, though there might be a few references I missed.
