Subject: [PATCH] powerpc/fadump: Mark fadump_calculate_reserve_size as __init
Date: Tue, 2 Mar 2021 12:50:14 -0700 [thread overview]
Message-ID: <20210302195013.2626335-1-nathan@kernel.org> (raw)
If fadump_calculate_reserve_size() is not inlined, there is a modpost
warning:
WARNING: modpost: vmlinux.o(.text+0x5196c): Section mismatch in
reference from the function fadump_calculate_reserve_size() to the
function .init.text:parse_crashkernel()
The function fadump_calculate_reserve_size() references
the function __init parse_crashkernel().
This is often because fadump_calculate_reserve_size lacks a __init
annotation or the annotation of parse_crashkernel is wrong.
fadump_calculate_reserve_size() calls parse_crashkernel(), which is
marked as __init and fadump_calculate_reserve_size() is called from
within fadump_reserve_mem(), which is also marked as __init.
Mark fadump_calculate_reserve_size() as __init to fix the section
mismatch. Additionally, remove the inline keyword as it is not necessary
to inline this function; the compiler is still free to do so if it feels
it is worthwhile since commit 889b3c1245de ("compiler: remove
CONFIG_OPTIMIZE_INLINING entirely").
Fixes: 11550dc0a00b ("powerpc/fadump: reuse crashkernel parameter for fadump memory reservation")
