But this is defined in include/asm/???.h  so you should be=20
able to set something more to your liking=20
(or rather to your archs liking).  It is true that it SHOULD=20
be defined as it is used to define=20
TICK_NSEC which is used to define the=20
jiffies<-->timeval/timespec conversions which would be VERY=20
slow it it were a variable.
Just make them variables, and compute them ONCE during boot.
ppc calls calibrate_decr() before enabling the timer interrupt anyways.

time_nsec is easy.=20
in a platfrom specific file do (very simplified):

extern unsigned long time_nsec;

void platform_specific_calibrate_decr()
{
	time_nsec =3D REAL_TIME_NSEC;
}

This (of course) will do nothing about LATCH and ACTHZ that might be
used other places.
