    The PnP errors are due to an overly broad Kconfig dependency list, and
    are resolved with the following patch:
    <https://lkml.org/lkml/2016/5/1/100>. This patch should be applied first
    to prevent the PnP build for X86_64, when the X86_32 dependency is
    decoupled from the ISA Kconfig option in this current patch.

    See <https://lkml.org/lkml/2016/4/11/421> for the history behind these
    two patches.
