Sorry for the delayed response. We are on holiday.

These patches were written over a year ago. I did not send it to lkml.

I did not continue development because I remember seeing an equivalent fix in another patch or a newer kernel than the one against which I wrote the patch.

I am busy with other things at this time, so if Kim (or someone else) wants to rewrite the patch to use cpumap, he should do it because I don't have the time to do it.
