    x86, GART: Disable GART table walk probes · 260133ab
    Borislav Petkov authored
    Current code tramples over bit F3x90[6] which can be used to
    disable GART table walk probes. However, this bit should be set
    for performance reasons (speed up GART table walks). We are
    allowed to do that since we put GART tables in UC memory later
    anyway. Make it so.
