v5->v6:
  - patch 6/7: mpe reported that the perf-hwbreak.c doesn't compile with older
    gcc:
         perf-hwbreak.c:182:2: error: dereferencing type-punned pointer will
         break strict-aliasing rules [-Werror=strict-aliasing]
             temp16 = *((__u16 *)target);
             ^
    Fixed that.
