I have read the comments that others made on the series and overall
agree. I've seen that you intend to prepare a v2. I think we must
first decide how to better deal with emulated syscalls as I said in
an earlier message. Probably that we should just add a specific test
case for EFAULT in nolibc-test since it's the only one (I think) that
risks to trigger crashes with emulated syscalls. We could also imagine
dealing with the signal ourselves but I'm not that keen on going to
implement signal() & longjmp() for now :-/

Regardless, in order to clean the things up and relieve you from the
non-rv32 stuff, I've just reverted the two patches that your series
reverts (1 & 2), and added the EOVERFLOW one (3). I'm pushing this to
branch 20230528-nolibc-rv32+stkp5.

Regards,
Willy
