Yes, it would work just as well, my point was just that it is somewhat
confusing to have every architecture do it differently, and that I
prefer the way Arm (and also ppc, x86 etc) handles it today.

On MIPS, most platforms are not yet part of MIPS_GENERIC, so
they are fairly free to pick whatever method works best and is
consistent with the rest of the kernel.
