Message-Id: <1413468142-32628-1-git-send-email-riku.voipio@linaro.org> Date: Thu, 16 Oct 2014 17:02:22 +0300 From: Riku Voipio <riku.voipio@...aro.org> To: Peter Oberparleiter <oberpar@...ux.vnet.ibm.com>, linux-kernel@...r.kernel.org Cc: linux-arm-kernel@...ts.infradead.org, Andrew Morton <akpm@...ux-foundation.org>, Stephen Rothwell <sfr@...b.auug.org.au>, Riku Voipio <riku.voipio@...aro.org> Subject: [PATCH] gcov: enable GCOV_PROFILE_ALL from ARCH Kconfigs Following the suggestions from Andrew Morton and Stephen Rothwell, Dont expand the ARCH list in kernel/gcov/Kconfig. Instead, define a ARCH_HAS_GCOV_PROFILE_ALL bool which architectures can enable. set ARCH_HAS_GCOV_PROFILE_ALL on Architectures where it was previously allowed + ARM64 which I tested. Replaces earlier "gcov: add ARM64 to GCOV_PROFILE_ALL" patch.
