#     radix and hash.

WARNING: modpost: vmlinux.o(.text+0xe2e0): Section mismatch in reference from the function start_secondary() to the function .init.text:setup_kuep()
The function start_secondary() references
the function __init setup_kuep().
This is often because start_secondary lacks a __init 
annotation or the annotation of setup_kuep is wrong.
