Two comments here:
First I think the current riscv compat.h is completely bogus. As you mentioned riscv does not actually have a compat mode, so having a compat.h makes no sensse at all, and the COMPAT_UTS_MACHINE override which is the only thing implemented is included in that statement.
Second I think abusing compat.h for old syscall compatibility of any form is a really bad idea. I think you need to split that part out, and preferably not using compat in the name, but something like old-time.h or time32.h for the name.
