====================
pull-request: bpf-next 2018-01-19

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

The main changes are:

1) bpf array map HW offload, from Jakub.

2) support for bpf_get_next_key() for LPM map, from Yonghong.

3) test_verifier now runs loaded programs, from Alexei.

4) xdp cpumap monitoring, from Jesper.

5) variety of tests, cleanups and small x64 JIT optimization, from Daniel.

6) user space can now retrieve HW JITed program, from Jiong.

Note there is a minor conflict between Russell's arm32 JIT fixes
and removal of bpf_jit_enable variable by Daniel which should
be resolved by keeping Russell's comment and removing that variable.
