All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text+0xb0e0): Section mismatch in reference from the function setup_kup() to the function .init.text:setup_kuap()
   The function setup_kup() references
   the function __init setup_kuap().
   This is often because setup_kup lacks a __init
   annotation or the annotation of setup_kuap is wrong.
