Subject[PATCH] 2.5.43-tick
Date
This patch appears not to be in 2.5.43, but applies cleanly.

On some ARM platforms, CLOCK_TICK_RATE is not a constant (it is specified
at boot time), which means that TICK_USEC/TICK_NSEC is not constant.
We therefore can not initialise static variables with these definitions;
they must be done at run time.
