    x86: don't use P6_NOPs if compiling with CONFIG_X86_GENERIC

    Commit: 959b3be64cab9160cd74532a49b89cdd918d38e9

    x86: don't use P6_NOPs if compiling with CONFIG_X86_GENERIC

    P6_NOPs are definitely not supported on some VIA CPUs, and possibly
    (unverified) on AMD K7s.  It is also the only thing that prevents a
    686 kernel from running on Transmeta TM3x00/5x00 (Crusoe) series.

    The performance benefit over generic NOPs is very small, so when
    building for generic consumption, avoid using them.
