Ugh, where that is say that? I can easily imagine a processor where
your argument would not hold true.
Zoltan> Shall we use the system wide minimum stride ?
Yes, that would be fine, too.
Zoltan> Why does not the SAL calculate it ? :-)
BTW: instead of calculating the min log2 stride, I'd just export the
actual stride. No point doing that in flush_cache over and over
again.
