You are saying "all archs" but ...

... you only switch x86/PPC to div64.h.

I guess this is because for arm we have a different implementation for 
32-bits. The 64-bits version is the same as x86/PPC.
So I wonder if it is possible to include asm-generic/div64.h from 
arch/arm/include/asm/div64.h?
This will avoid duplicating some code.

Cheers,
