Does anyone object to setting HZ at boot? I suspect nothing else will
make everyone happy.
This will really mess up the jiffie_to_* and *_to_jiffie conversions. They rely
in a rather large way on the complier doing all the heavy lifting. If HZ is a
variable we introduce a LOT of runtime overhead here. (Try make kernel/itimer.i
and look for jiffies_to_t* and friends.)
