Russel, Michael,
Looks like the reported problem comes from b28c97505eb1 ("powerpc/64:
Setup KUP on secondary CPUs")
(https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git/commit/?h=next&id=b28c97505eb1a5265e367c398c3406be6ce5e313)
Is it really necessary to remove the __init tag on setup_kup() ?

All warnings (new ones prefixed by >>):
WARNING: vmlinux.o(.text+0xb038): Section mismatch in reference from the
function setup_kup() to the function .init.text:setup_kuep()
The function setup_kup() references
the function __init setup_kuep().
This is often because setup_kup lacks a __init
annotation or the annotation of setup_kuep is wrong.
