I'm not sure what this is about. The corresponding patch is here:
https://patchwork.kernel.org/patch/10624567/
I see some division in the patch but I can't immeaditely see what's
wrong. So is this a problem in the bot, in parisc architecture or with
the patch? Anyone have any good ideas? Arnd?

I think the problem is that 'clock_freq' is a 'u64', which means we can't use
a normal 32-bit division. It looks like it cannot actually go beyond the
range of a u32, so changing the type should be sufficient.
