Hi,

A new set of bpf insns have been recently added in llvm with flag
[-mcpu=v4](https://reviews.llvm.org/D144829). In the kernel,
x86_64 and arm64 have implemented -mcpu=v4 support:
   x86_64: 
https://lore.kernel.org/all/20230728011143.3710005-1-yonghong.song@linux.dev/
   arm64: 
https://lore.kernel.org/bpf/20230815154158.717901-1-xukuohai@huaweicloud.com/

The following arch's do not have -mcpu=v4 support yet:
   arm, mips, nfp, powerpc, riscv, sc90, sparc and x86_32

If you have a chance, could you take a look at what
x86_64/arm64 does and add support to the above arch'es?

Thanks!

Yonghong
