I tested this...
With HZ=1000:
- normal boot: calibrate_delay() took 23 milliseconds
- specifying lpj=xxx: calibrate_delay() took 43 microseconds.
With HZ=100:
- normal boot: calibrate_delay() took 264 milliseconds
- specifying lpj=xxx: calibrate_delay() took 43 microseconds.
No adverse behaviour was observed.
This will be a big improvement for embedded folks.
