    Subject[PATCH] perf/core: declare the percpu variable properly
    Date
    Sparse reports the current declaration of percpu variable with
    below warning

    warning: incorrect type in initializer (different address spaces)
    expected void const [noderef] <asn:3>*__vpp_verify
    got struct perf_cpu_context *<noident>

    Fix it by declaring it properly.
