>> WARNING: vmlinux.o(.text+0x4ec4): Section mismatch in reference from the function debug_stub() to the function .init.text:start_kernel()
   The function debug_stub() references
   the function __init start_kernel().
   This is often because debug_stub lacks a __init
   annotation or the annotation of start_kernel is wrong.
