Maybe this problem seems dumb, but I have no idea to adapt both riscv32 
and riscv64. I have tried to use 'const __be64 *' and 'const __be32 *' 
pointer in patch v4, but I forgot to test them in riscv32, and it turns 
out the code failed to compile due to my mistake of defining 'const 
__be64 * p_ul' and of course it wouldn't be work for riscv32. Maybe I 
need some inspiration for this problem, or I still think it better to 
use 'unsigned long const *' since it works fine in both riscv64 and riscv32.

Looking forward to your reply and guidance.

Yours,

Zhihang
