====================
pull-request: bpf 2018-06-12

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

The main changes are:

1) Avoid an allocation warning in AF_XDP by adding __GFP_NOWARN for the
   umem setup, from Björn.

2) Silence a warning in bpf fs when an application tries to open(2) a
   pinned bpf obj due to missing fops. Add a dummy open fop that continues
   to just bail out in such case, from Daniel.

3) Fix a BPF selftest urandom_read build issue where gcc complains that
   it gets built twice, from Anders.
