Add Zbb support [0] to optimize code size and performance of RV64 JIT.
Meanwhile, adjust the code for unification and simplification. Tests
test_bpf.ko and test_verifier have passed, as well as the relative
testcases of test_progs*.

Lehui,

Sorry for the delay. I'm chasing a struct_ops RISC-V BPF regression in
6.8-rc1, I will need to wrap my head around that prior reviewing
properly.

Oh, I also found the problem with struct ops and fixed it

Pu, with your patch bpf_iter_setsockopt, bpf_tcp_ca, and dummy_st_ops
passes!

Please spin a proper fixes patch, and feel free to add:

Tested-by: Björn Töpel <redacted>
Acked-by: Björn Töpel <bjorn@kernel.org>

Is that in a hurry? If not, I would like to send it with the upcoming
patchset.

This is a separate fix, right? What patchset are you referring to where
the fix would be in?

Yes, you are right! I'll send a bug fix patch as soon as possible. 
Coming soon is the bpf_prog_pack for RV64 Trampoline, which currently 
does not seem to be related to the bugfix, will populate the commit 
message and send it later.😁

As of now 6.8-rc1 is broken! It would be a great with a fix asap...


Cheers,
Björn
