====================
pull-request: bpf-next 2019-09-16

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

The main changes are:

1) Now that initial BPF backend for gcc has been merged upstream, enable
   BPF kselftest suite for bpf-gcc. Also fix a BE issue with access to
   bpf_sysctl.file_pos, from Ilya.

2) Follow-up fix for link-vmlinux.sh to remove bash-specific extensions
   related to recent work on exposing BTF info through sysfs, from Andrii.

3) AF_XDP zero copy fixes for i40e and ixgbe driver which caused umem
   headroom to be added twice, from Ciara.

4) Refactoring work to convert sock opt tests into test_progs framework
   in BPF kselftests, from Stanislav.

5) Fix a general protection fault in dev_map_hash_update_elem(), from Toke.

6) Cleanup to use BPF_PROG_RUN() macro in KCM, from Sami.
