Test kernel can be found here:
https://people.canonical.com/~phlin/kernel/lp-2001618-ppcbpf/
Steps:
1. Reboot with the patched kernel
2. Run:
sudo dmesg -C
sudo modprobe test_bpf
sudo dmesg
Tested with Power9 node baltar, with the patched kernel there will be no failure reported by the test_bpf:
test_bpf: Summary: 1026 PASSED, 0 FAILED, [1014/1014 JIT'ed]
[Where problems could occur]
This patchset just broaden the BPF operations support on ppc64, we might see some new failures when using these instruction somewhere in the future. |

Cascardo: The existing atomic operations may regress as well, since they now produce different code. |
