Hi David,

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Lots of libbpf improvements: i) addition of new APIs to attach BPF
   programs to tracing entities such as {k,u}probes or tracepoints,
   ii) improve specification of BTF-defined maps by eliminating the
   need for data initialization for some of the members, iii) addition
   of a high-level API for setting up and polling perf buffers for
   BPF event output helpers, all from Andrii.

2) Add "prog run" subcommand to bpftool in order to test-run programs
   through the kernel testing infrastructure of BPF, from Quentin.

3) Improve verifier for BPF sockaddr programs to support 8-byte stores
   for user_ip6 and msg_src_ip6 members given clang tends to generate
   such stores, from Stanislav.

4) Enable the new BPF JIT zero-extension optimization for further
   riscv64 ALU ops, from Luke.

5) Fix a bpftool json JIT dump crash on powerpc, from Jiri.

6) Fix an AF_XDP race in generic XDP's receive path, from Ilya.

7) Various smaller fixes from Ilya, Yue and Arnd.
