   overflows when mmaping a 2G ringbuf and rejection of invalid reservation
   sizes, from Hou Tao.

2) Fix a buggy return pointer in libbpf for attach_raw_tp function, from Jiri Olsa.

3) Fix a local storage BPF map bug where the value's spin lock field can get
   initialized incorrectly, from Xu Kuohai.
