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.
