We are in the process of removing all the __cpuinit annotations. While working on making that change, an existing problem was made evident: WARNING: arch/x86/kernel/built-in.o(.text+0x198f2): Section mismatch in reference from the function cpu_init() to the function .init.text:load_ucode_ap() The function cpu_init() references the function __init load_ucode_ap(). This is often because cpu_init lacks a __init annotation or the annotation of load_ucode_ap is wrong. This now appears because in my working tree, cpu_init() is no longer tagged as __cpuinit, and so the audit picks up the mismatch. The 2nd hypothesis from the audit is the correct one, as there was an incorrect __init tag on the prototype in the header (but __cpuinit was used on the function itself.) The audit is telling us that the prototype's __init annotation took effect and the function did land in the .init.text section. Checking with objdump on a mainline tree that still has __cpuinit shows that the __cpuinit on the function takes precedence over the __init on the prototype, but that won't be true once we make __cpuinit a no-op. Even though we are removing __cpuinit, we temporarily align both the function and the prototype on __cpuinit so that the changeset can be applied to stable trees if desired.
