This is a note to let you know that I've just added the patch titled powerpc/fadump: Mark fadump_calculate_reserve_size as __init to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: powerpc-fadump-mark-fadump_calculate_reserve_size-as.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 35fab735662880c102f79eb9f92342a4f23a72d0 Author: Nathan Chancellor <nathan@xxxxxxxxxx> Date: Tue Mar 2 12:50:14 2021 -0700 powerpc/fadump: Mark fadump_calculate_reserve_size as __init [ Upstream commit fbced1546eaaab57a32e56c974ea8acf10c6abd8 ] 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").
