    linuxkpi: Document why <linux/cpufeaure.h> has an include commentted out
    
    <linux/cpufeature.h> on Linux includes <linux/init.h>. We don't have the
    latter on FreeBSD yet, so let's comment this include for now. It is
    still referenced because sometimes, consumers of headers rely
    voluntarily or not on the namespace pollution.
