The main changes are:

1) fix bpf uapi pointers for 32-bit architectures, from Daniel.

2) improve verifer ability to handle progs with a lot of branches, from Alexei.

3) strict btf checks, from Yonghong.

4) bpf_sk_lookup api cleanup, from Joe.

5) other misc fixes

Please consider pulling these changes from:
