...the number looks suspiciously like clk/2 but don't let that fool you.
It is actually the number of white mice on pogo sticks required to give
off the same amount of heat as your CPU.

Seriously tho' - it calibrates the delay fcn in ./include/linux/delay.h
so that if you divide the arg passed to it by "loops_per_sec", you
will actually have a time value. Also note the other addition to delay.h,
noted in the release notes. (see below.)

============================

INTERNAL kernel changes:

[...]

 - udelay() function for short delays (busy-waiting) added.  Used
   currently only by the QIC driver.
