Public bug reported:
SRU Justification:
[Impact]
* bpf selftest do not compile. See the error below.
Commit "bpf: Allow reads from uninit stack" introduced the usage of '__failure',
without bringing the commit where this is defined.
This prevents us from running other tests and it also affects the netselfts
because they are dependant on it.
Logs:

[Fix]
* While discussing with upstream a revert of this commit will be the fix
for now.
[Test Plan]
* Revert, build the kernel, run the ubuntu_bpf_selftests and see it they
build.
