>> WARNING: modpost: vmlinux.o(.text.unlikely+0x34f8): Section mismatch in reference from the function sg_pool_index.part.0() to the function .init.text:memblock_alloc_try_nid()
The function sg_pool_index.part.0() references
the function __init memblock_alloc_try_nid().
This is often because sg_pool_index.part.0 lacks a __init
annotation or the annotation of memblock_alloc_try_nid is wrong.
