====================
Two fixes that deal with buggy usage of bpf_helper_changes_pkt_data()
in the sense that they also reload cached skb data when there's no
skb context but xdp one, for example. A fix where skb meta data is
reloaded out of the wrong register on helper call, rest is test cases
and making sure on verifier side that there's always the guarantee
that ctx sits in r1. Thanks!
