There seem to be a separate set of functions for applying smp lock prefixes and more "general" alternatives. I guess the "general" alternatives and paravirt could be declared __init, and text_poke users would have to use it responsibly. Such as: __init apply_alternatives __init apply_paravirt non init: alternatives_smp_* alternatives_smp_ Mathieu > -Andi > -- Mathieu Desnoyers Computer Engineering Ph.D. Student, Ecole Polytechnique de Montreal OpenPGP key fingerprint: 8CD5 52C3 8E3C 4140 715F BA06 3F25 A8FE 3BAE 9A68 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
