Subject: [PATCH] powerpc/xive: Do not mark xive_request_ipi() as __init
Date: Mon, 16 Aug 2021 11:57:11 -0700 [thread overview]
Message-ID: <20210816185711.21563-1-nathan@kernel.org> (raw)
Compiling ppc64le_defconfig with clang-14 shows a modpost warning:
WARNING: modpost: vmlinux.o(.text+0xa74e0): Section mismatch in
reference from the function xive_setup_cpu_ipi() to the function
.init.text:xive_request_ipi()
The function xive_setup_cpu_ipi() references
the function __init xive_request_ipi().
This is often because xive_setup_cpu_ipi lacks a __init
annotation or the annotation of xive_request_ipi is wrong.
xive_request_ipi() is called from xive_setup_cpu_ipi(), which is not
__init, so xive_request_ipi() should not be marked __init. Remove the
attribute so there is no more warning.
Fixes: cbc06f051c52 ("powerpc/xive: Do not skip CPU-less nodes when creating the IPIs")
