It has to be, %99 of sparc64 userland is 32-bit.

This is an unreasonable requirement, all kernel ABIs should work in
32-bit compat tasks.  And when it's very difficult or impossible to
make it work, there should be a new ABI to transition to that does
work in compat mode and in particular would work now for the user.
