>> WARNING: mm/built-in.o(.text+0x79ac): Section mismatch in reference from the (unknown reference) (unknown) to the variable .init.rodata:__setup_str_setup_fail_page_alloc
The function (unknown)() references
the variable __initconst __setup_str_setup_fail_page_alloc.
This is often because (unknown) lacks a __initconst
annotation or the annotation of __setup_str_setup_fail_page_alloc is wrong.
