I would be happier if you didn't change this (or at least put it in its 
own patch explaining why it's not going to slow down other platforms).

It would essentially be a revert of 01c9348c7620 ("powerpc: Use hardware
RNG for arch_get_random_seed_* not arch_get_random_*")

Which would be ironic :)

You expect me to remember things I did 6 years ago? :)

I'll take this part out.  My thinking originally was that since darn
on Microwatt is a single-cycle instruction, it would be faster to use
darn every time rather than run a software PRNG seeded from darn.
It's not critical though.
