====================
pull-request: bpf 2018-05-24

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

The main changes are:

1) Fix a bug in the original fix to prevent out of bounds speculation when
   multiple tail call maps from different branches or calls end up at the
   same tail call helper invocation, from Daniel.

2) Two selftest fixes, one in reuseport_bpf_numa where test is skipped in
   case of missing numa support and another one to update kernel config to
   properly support xdp_meta.sh test, from Anders.

 ...

Would be great if you have a chance to merge net into net-next after that.

The verifier fix would be needed later as a dependency in bpf-next for
upcomig work there. When you do the merge there's a trivial conflict on
BPF side with 849fa50662fb ("bpf/verifier: refine retval R0 state for
bpf_get_stack helper"): Resolution is to keep both functions, the
do_refine_retval_range() and record_func_map().
