====================
pull-request: bpf-next 2018-07-20

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

The main changes are:

1) Add sharing of BPF objects within one ASIC: this allows for reuse of
   the same program on multiple ports of a device, and therefore gains
   better code store utilization. On top of that, this now also enables
   sharing of maps between programs attached to different ports of a
   device, from Jakub.

2) Cleanup in libbpf and bpftool's Makefile to reduce unneeded feature
   detections and unused variable exports, also from Jakub.

3) First batch of RCU annotation fixes in prog array handling, i.e.
   there are several __rcu markers which are not correct as well as
   some of the RCU handling, from Roman.

4) Two fixes in BPF sample files related to checking of the prog_cnt
   upper limit from sample loader, from Dan.

5) Minor cleanup in sockmap to remove a set but not used variable,
   from Colin.
