This requires an architecture specific compat routine as u64s are passed
in odd/even (high/low) register pairs on ppc32.

Doesn't that apply to ARM and to 32-bit MIPS too? And perhaps others?

Unfortunately in the MIPS case you'll have to do some ifdef'ing because
the order of the "high" and "low" sub-part arguments is dependant upon
endianness and MIPS can be both big and little endian.
