    There was a bit of a discussion at the time I submitted the patch:

    https://lkml.org/lkml/2012/4/23/606

    Basically CMA had been in for a while already in a released kernel
    before I submitted a patch to allow it to be disabled. So the patch
    preserves existing behaviour.

    Regards,
