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.
