From: Nathan Chancellor <nathan@kernel.org> stable inclusion from stable-5.10.67 commit 49e4c83db88537b23a1f662b234776c73b97e3aa bugzilla: 182619 https://gitee.com/openeuler/kernel/issues/I4EWO7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit d04691d373e75c83424b85c0e68e4a3f9370c10d ] 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.
