====================
pull-request: bpf 2018-02-28

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

The main changes are:

1) Add schedule points and reduce the number of loop iterations
   the test_bpf kernel module is performing in order to not hog
   the CPU for too long, from Eric.

2) Fix an out of bounds access in tail calls in the ppc64 BPF
   JIT compiler, from Daniel.

3) Fix a crash on arm64 on unaligned BPF xadd operations that
   could be triggered via interpreter and JIT, from Daniel.

Please not that once you merge net into net-next at some point, there
is a minor merge conflict in test_verifier.c since test cases had
been added at the end in both trees. Resolution is trivial: keep all
the test cases from both trees.
