Regardless, the patch is correct so I'll pick it up, thanks. cheers > diff --git a/drivers/cpuidle/cpuidle-pseries.c b/drivers/cpuidle/cpuidle-pseries.c > index bba449b77641..7e7ab5597d7a 100644 > --- a/drivers/cpuidle/cpuidle-pseries.c > +++ b/drivers/cpuidle/cpuidle-pseries.c > @@ -403,7 +403,7 @@ static void __init fixup_cede0_latency(void) > * pseries_idle_probe() > * Choose state table for shared versus dedicated partition > */ > -static int pseries_idle_probe(void) > +static int __init pseries_idle_probe(void) > { > > if (cpuidle_disable != IDLE_NO_OVERRIDE) > > base-commit: a6cae77f1bc89368a4e2822afcddc45c3062d499 > -- > 2.33.0.rc0

After commit 7cbd631d4dec ("cpuidle: pseries: Fixup CEDE0 latency only for POWER10 onwards"), pseries_idle_probe() is no longer inlined when compiling with clang, which causes a modpost warning: WARNING: modpost: vmlinux.o(.text+0xc86a54): Section mismatch in reference from the function pseries_idle_probe() to the function .init.text:fixup_cede0_latency() The function pseries_idle_probe() references the function __init fixup_cede0_latency(). This is often because pseries_idle_probe lacks a __init annotation or the annotation of fixup_cede0_latency is wrong. pseries_idle_probe() is a non-init function, which calls fixup_cede0_latency(), which is an init function, explaining the mismatch. pseries_idle_probe() is only called from pseries_processor_idle_init(), which is an init function, so mark pseries_idle_probe() as __init so there is no more warning.
