The routine that did this used udelay, which will hang forever when the timebase is stopped, since udelay now spins until the timebase reaches a certain value. The end result is that the kernel would hang when bringing up the second CPU. This fixes it by using a simple loop which just does a fixed number of iterations to generate the delay. These old systems were all clocked at around 200 MHz or so, so a fixed number of iterations is acceptable.
