Equivalently you need to be able to modify orig_a0 for changing arg0, no?

Ok.

Greg, could you accept a backport a new API parameter for PTRACE_GETREGSET/PTRACE_SETREGSET to 4.19 LTS branch?

Fix the problem properly and put a proper Fixes tag on it and worry about the backport later.

Thanks,

I wouldn't worry about backporting to the 4.19 kernel. It's essentially prehistoric for RISC-V. There's no device tree support for any hardware. Also, 4.19 will be going EOL very soon (December 2024).
