[PATCH] uml: timer initialization cleanup
This cleans up the mess that is the timer initialization. There used to be two timer handlers - one that basically ran during delay loop calibration and one that handled the timer afterwards. There were also two sets of timer initialization code - one that starts in user code and calls into the kernel side of the house, and one that starts in kernel code and calls user code. This eliminates one timer handler and consolidates the two sets of initialization code.
