Date: Tue, 10 Oct 2017 21:51:28 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Juri Lelli <juri.lelli@....com>, Sudeep Holla <sudeep.holla@....com> Subject: [PATCH 4.13 160/160] base: arch_topology: fix section mismatch build warnings 4.13-stable review patch. If anyone has any objections, please let me know. ------------------ From: Sudeep Holla <sudeep.holla@....com> commit 452562abb5b76c14449dead2a7113f641893e8bc upstream. Commit 2ef7a2953c81 ("arm, arm64: factorize common cpu capacity default code") introduced init_cpu_capacity_callback and init_cpu_capacity_notifier which are referenced from initcall and are missing __init{,data} annotations resulting the below section mismatch build warnings. "WARNING: vmlinux.o(.text+0xbab790): Section mismatch in reference from the function init_cpu_capacity_callback() to the variable .init.text:$x The function init_cpu_capacity_callback() references the variable __init $x. This is often because init_cpu_capacity_callback lacks a __init annotation or the annotation of $x is wrong." This patch fixes the above build warnings by adding the required annotations.
