Given that redefining them is rather error prone, as shown by parisc getting the opcodes wrong currently, just use the existing definitions for the compat handling. In theory we could try to hide them from userspace; but given that only MIPS manages to properly do that while the asm-generic version used by most architectures relies on a Kconfig symbol that is never set by userspace there doesn't seem to be much of a point to even bother.
