Please have a look at arch/riscv and arch/nds32 for this, I think it can be
simplified. This is an incompatible change of course, but when we change
the system call ABI anyway, that is the right time to do it.

In particular the constants should come from the asm-generic headers
rather than being duplicated. If you need anything special, it may be
better to modify the generic headers.
