All warnings (new ones prefixed by >>):

>> WARNING: arch/sparc/built-in.o(.text.unlikely+0x2e4): Section mismatch in reference from the function find_node() to the function .init.text:find_mlgroup()
   The function find_node() references
   the function __init find_mlgroup().
   This is often because find_node lacks a __init
   annotation or the annotation of find_mlgroup is wrong.
