>> WARNING: mm/built-in.o(.text+0x21122): Section mismatch in reference from the function _get_kmalloc_cache_name() to the variable .init.rodata:_kmalloc_info
   The function _get_kmalloc_cache_name() references
   the variable __initconst _kmalloc_info.
   This is often because _get_kmalloc_cache_name lacks a __initconst
   annotation or the annotation of _kmalloc_info is wrong.
