Hmm, I bet it had something to do with some sort of gcc optimization, and is mostly harmless. > annotation or the annotation of nmi_ipi_mask is wrong. What gcc are you using and can you send your .config. remote_ipi() (which is annotated as __init), calls cpumask_empty() (a static inlined function) with to_cpumask(nmi_ipi_mask). There's nothing wrong here. I don't see anyway that cpumask_empty() could use nmi_ipi_mask after boot up. Seeing that it's not cpumask_empty(), but cpumask_empty.constprop.3 tells me that gcc probably created some function from the static inline function of cpumask_empty() and that causes the section mismatch test to give a false error. If anything should be fixed here, it is to find a way to fix the section mismatch test from reporting bogus errors like this. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
