>> WARNING: modpost: vmlinux.o(.text+0x1e7210c): Section mismatch in reference from the function ima_free_kexec_buffer() to the function .meminit.text:memblock_phys_free()
The function ima_free_kexec_buffer() references
the function __meminit memblock_phys_free().
This is often because ima_free_kexec_buffer lacks a __meminit
annotation or the annotation of memblock_phys_free is wrong.
