>> WARNING: modpost: vmlinux.o(.text+0x1e10e): Section mismatch in reference from the variable $BB2_91 to the function .init.text:loongson2_sc_init()
The function $BB2_91() references
the function __init loongson2_sc_init().
This is often because $BB2_91 lacks a __init
annotation or the annotation of loongson2_sc_init is wrong.
