Great! I may just send a pull request to you, after some fixes (see
below).

I'll keep it around for now, but this should go as a warning to Dmitry,
to get something using it soon, or they may be dropped.

Also, Dmitry found a few bugs with the current
syscall_set/get_arguments() on some of the archs (riscv and csky). Which
I'll add at the front of this series and update my changes to keep the
same logic.

Then I'll post a non RFC version.
