The tick of some PowerPC cpu is running at high frequency and it can be used to get microsecond precision from it. Make use of div64 to achieve this precision in ticks2usec.
Which problem are you trying to fix?
Where exactly do we need very high accuracy?
What is the overhead of using do_div() versus the old, simple code?
Best regards,
Wolfgang Denk
