The following two selftest cases triggers oops on LoongArch:
$ ./test_progs -a ns_bpf_qdisc -a tracing_struct
This small series tries to fix/workaround these issues.
See individual commit for details.
While at it, remove a duplicated flags check in __arch_prepare_bpf_trampoline().
v1 -> v2:
* collect Acked-by/Tested-by tags
* update sign_extend() in patch 2 as suggested by Huacai
Hengqi Chen (3):
LoongArch: BPF: Remove duplicated flags check
LoongArch: BPF: Sign extend struct ops return values properly
LoongArch: BPF: No support of struct argument in trampoline programs
