Yeah, let's call it simply "cpu_parse_early_param". Also, I forgot to says this, sorry about that, but can you pls do your patch ontop of tip/master: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/log/ because there are other changes in that area and your patch as is, doesn't apply. Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
