From d75f054a2cf0614ff63d534ff21ca8eaab41e713 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Mon, 9 Feb 2009 00:43:36 +0100 Subject: parisc: add ftrace (function and graph tracer) functionality This patch adds the ftrace debugging functionality to the parisc kernel. It will currently only work with 64bit kernels, because the gcc options -pg and -ffunction-sections can't be enabled at the same time and -ffunction-sections is still needed to be able to link 32bit kernels.
