If there's any sort of section specification, that should suffice, I think.
The problem might come that jiffies and jiffies_64 don't coincide at the same
address because FRV is BE not LE.
It ought to be possible to make jiffies 64-bit on FRV since it has double-word
instructions that can load/store aligned 64-bit values atomically to/from a
register pair. That might require some compiler magic, though. I'll have to
try and work out if that's possible.
