    NAK.

    If we really want to stop checking the cpu feature and unconditionally
    write the MSR, then there should be a single patch that does it. If
    we don't, then we should not make this change, since it will make the
    very useful warning if we screwed it up go away.

    I think we should continue checking the cpu feature, personally. I
    also thing that, if we make the change, it should not be part of the
    FSGSBASE series.
