>> WARNING: vmlinux.o(.text.unlikely+0x3e94): Section mismatch in reference from the function bitmap_copy_clear_tail() to the variable .init.rodata:__setup_str_initcall_blacklist
   The function bitmap_copy_clear_tail() references
   the variable __initconst __setup_str_initcall_blacklist.
   This is often because bitmap_copy_clear_tail lacks a __initconst
   annotation or the annotation of __setup_str_initcall_blacklist is wrong.
