Two patches, fixing bugs added in 5.1 and 5.5

I have a followup patch for bpf-next, replacing the u64 fields
in struct bpf_prog_stats with u64_stats_t ones to avoid
possible sampling errors.

Eric Dumazet (2):
  bpf: avoid races in __bpf_prog_run() for 32bit arches
  bpf: fixes possible race in update_prog_stats() for 32bit arches
