btw we can hide all of this a lot nicer from just about the entire kernel by reducing the usage of both HZ and jiffies in drivers/non platform code. That isn't hard; msleep() is a good step forward there already; the next step is a nicer api for add_timer/mod_timer that is both relative and in miliseconds; with those 2 the majority of code that has "knowledge" about this shrinks to near zero. Once we have that the actual implementation of this in the background matters a whole lot less.
