[X][SRU][PATCH 0/1] test_bpf: flag tests that cannot be jited on s390x

[Po-Hsu Lin]

== SRU Justification ==
In the ubuntu_bpf_jit test, it will insert the test_bpf module to perform
the test. There will be 4 failures reported on s390x instances by the test,
3 of them were simply because they cannot be jited on s390x:
  * test_bpf: #243 BPF_MAXINSNS: Ctx heavy transformations FAIL to prog_create err=-524 len=4096
  * test_bpf: #244 BPF_MAXINSNS: Call heavy transformations FAIL to prog_create err=-524 len=4096
  * test_bpf: #249 BPF_MAXINSNS: ld_abs+get_processor_id FAIL to prog_create err=-524 len=4096

(For another failure "ld_abs+vlan_push/pop" please check bug 1868243)

== Fix ==
* 3203c901 (test_bpf: flag tests that cannot be jited on s390)
Only Xenial needs this patch, and it needs to be backported to Xenial
as some test case does not exist.

== Test ==
Test kernel could be found here:
https://people.canonical.com/~phlin/kernel/lp-1768452-bpf-jit/

The test will be marked as pass with the patched kernel:
test_bpf: #243 BPF_MAXINSNS: Ctx heavy transformations PASS
test_bpf: #244 BPF_MAXINSNS: Call heavy transformations PASS
test_bpf: #249 BPF_MAXINSNS: ld_abs+get_processor_id PASS

== Regression Potential ==
Low, change limited to the test_bpf module itself and specific to s390x,
no impact to real functions.
