tvtohz() was originally designed for tsleep() and timeout() operations but
it is also used to time nanosleep() ops.  The problem is that in order to
compensate for the fact that a clock interrupt might occur just after a
thread blocks or registers a timeout, this function effectively added +1
to the returned value plus added another +1 for timeouts that were not
integer multiples if the clock interrupt frequency.

Split tvtohz() into two routines: tvtohz_low() and tvtohz_high().
tvtohz_low() does not do any compensation, tvtohz_high() does.

Add the kern.sleep_hardloop sysctl, which defaults to 0 (off).  If set to
1 this will cause nanosleep() to attempt to time exactly the requested
interval (which could cost more cpu) rather then rounding it off to a
multiple of hz.  If set to 2 nanosleep() will only do the more rigid
timing for requests less then 1 second.   Also change the normal hz-baesd
case to only compensate by +1, not +2, in order to improve accuracy.

Matthew Dillon [Wed, 7 Jan 2004 10:59:09 +0000 (10:59 +0000)]
Compensate for the frequency error that occurs at higher 'hz' settings.
e.g. by default at 100hz the 8254 running at 1193182Hz needs
a count load of 11931.82, but we can only load integer values so the
clock interrupt winds up being slightly slower or faster then 100hz.
This will fix phase creep in things like nanosleep().
