>> WARNING: vmlinux.o(.text+0x9e640): Section mismatch in reference from the function hpet_cpuhp_online() to the function .init.text:hpet_init_clockevent()
   The function hpet_cpuhp_online() references
   the function __init hpet_init_clockevent().
   This is often because hpet_cpuhp_online lacks a __init
   annotation or the annotation of hpet_init_clockevent is wrong.
