aha, I see what happened. I did some asm -> c convesion [1]
two weeks ago. I also converted the sifive_cip_453_page_fault_trp etc.
to c as well, but I decided to not bring too many changes
in the last minute, so the last patch wasn't sent out, but
it's in my repo ;)

I will send out v2 soon. Thank you so much!
