Peter Zijlstra 9e3d6223d2 math64, timers: Fix 32bit mul_u64_u32_shr() and friends 
It turns out that while GCC-4.4 manages to generate 32x32->64 mult
instructions for the 32bit mul_u64_u32_shr() code, any GCC after that
fails horribly.

Fix this by providing an explicit mul_u32_u32() function which can be
architcture provided.
