This set contains a couple of misc updates: stack usage reduction
for perf_sample_data in tracing progs, reduction of stale data in
verifier on register state transitions that I still had in my queue
and few selftest improvements as well as bpf_set_hash() helper for
tc programs.

Series applied, thanks Daniel.
