Loongarch bpf selftests report

[Vincent Li]

Hi Folks,

I am able to finally complete the bpf selftests and generated a
selftests report here
https://www.bpfire.net/download/bpf_selftests.json.txt, here is the
command to skip the tests that could hang up the kernel and  generate
the rest of bpf selftests failed reports:

./test_progs --deny=module_attach --deny=ns_bpf_qdisc
--deny=struct_ops --deny=subprogs_extable --deny=tracing_struct
--deny=timer_lockup --json-summary="./bpf_selftests.json"

In my opinion after reading related bpf selftests code:

1. module_attach, subprogs_extable, tracing_struct are related issues,
that is fentry/fexit on kernel module function would hang up the
kernel.
2. ns_bpf_qdisc kernel panic is a separate issue and should not be tied to 1
3. intermittent timer_lockup test hang up kernel that could be
architecture independent.

Thanks,

Vincent
