    I have not come even close to reviewing this yet but I made a start on
    putting it through a series of tests. It fails to build on ppc64

    CC mm/slub.o

    I didn't look closely yet but cpu_info is an arch-specific variable.
    Checking to see if there is a known fix yet before setting aside time to
    dig deeper.
