These patches fix issues seen when cross-compiling eBPF samples on arm64.
Compared to [1], I dropped the controversial inline-asm patch and exploring
other options to fix it. However these patches are a step in the right
direction and I look forward to getting them into -next and the merge window.

Changes since v3:
- just a repost with acks

[1] https://lkml.org/lkml/2017/8/7/417

Joel Fernandes (4):
  samples/bpf: Use getppid instead of getpgrp for array map stress
  samples/bpf: Enable cross compiler support
  samples/bpf: Fix pt_regs issues when cross-compiling
  samples/bpf: Add documentation on cross compilation

Series applied with typo in patch #4 corrected.

Thanks.
