Subject: sh: Enable CONFIG_GCOV_PROFILE_ALL for sh
X-Git-Tag: v2.6.39-rc1~456^2~14^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d4f7e513234019a005c4d33477189f2a4e53bb9c;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git

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.
