Matija Glavinic Pecotic 34f41c0316 timers: Fix overflow in get_next_timer_interrupt 
For e.g. HZ=100, timer being 430 jiffies in the future, and 32 bit
unsigned int, there is an overflow on unsigned int right-hand side
of the expression which results with wrong values being returned.

Type cast the multiplier to 64bit to avoid that issue.
