Modified files:
sys/kern kern_clock.c
sys/conf options
sys/i386/conf LINT
Log:
Make timecounters more resistant to badly behaved SW/HW which locks
out interrupts for too long. If you still see the "calcru: negative
time..." message you can increase NTIMECOUNTER (see LINT).
Sideeffect is that a timecounter is required to not wrap around in
less than (1 + delta) seconds instead of the (1/hz + delta) required
until now.
Many thanks to: msmith, wpaul, wosch & bde
