    amd64: pmap.h put a guard around a pcpu.h function
    
    pmap_get_pcid() calls zpcpu_get() which is defined in pcpu.h.
    It is unclear why we do not include that header but like right
    above the change add another guard around pmap_get_pcid().
    This allows some LinuxKPI headers to compile again.
