This commit has no direct upstream equivalent. After commitd48016d748("mm,ima,kexec,of: use memblock_free_late from ima_free_kexec_buffer") in 5.15, there is a modpost warning for certain configurations: WARNING: modpost: vmlinux.o(.text+0xb14064): Section mismatch in reference from the function ima_free_kexec_buffer() to the function .init.text:__memblock_free_late() The function ima_free_kexec_buffer() references the function __init __memblock_free_late(). This is often because ima_free_kexec_buffer lacks a __init annotation or the annotation of __memblock_free_late is wrong. In mainline, there is no issue because ima_free_kexec_buffer() is marked as __init, which was done as part of commitb69a2afd5a("x86/kexec: Carry forward IMA measurement log on kexec") in 6.0, which is not suitable for stable. Mark ima_free_kexec_buffer() and its single caller ima_load_kexec_buffer() as __init in 5.15, as ima_load_kexec_buffer() is only called from ima_init(), which is __init, clearing up the warning.
