ARM: 8153/1: Enable gcov support on the ARM architecture (75c34906) · Commits · 戴 / test

Enable gcov support for ARM based on original patches by David Singleton and George G. Davis Riku - updated to patch to current mainline kernel. The patch has been submitted in 2010, 2012 - for symmetry, now in 2014 too. https://lwn.net/Articles/390419/ http://marc.info/?l=linux-arm-kernel&m=133823081813044 v2: remove arch/arm/kernel from gcov disabled files Cc: Andrey Ryabinin <a.ryabinin@samsung.com> Cc: Naresh Kamboju <naresh.kamboju@linaro.org> Acked-by:
