From d4f7e513234019a005c4d33477189f2a4e53bb9c Mon Sep 17 00:00:00 2001 From: Chris Smith Date: Fri, 12 Nov 2010 16:26:54 +0100 Subject: [PATCH] sh: Enable CONFIG_GCOV_PROFILE_ALL for sh This patch enables gcov kernel profiling over the whole kernel for sh. Profiling of specific files individually already worked. A handful of files have to be explicitly excluded from the profiling to avoid breaking things, notably pmb.c.
