Hi,
I posted this about 1 month ago (as [RFC]), to no avail.
However, tonight Andi needs it for pause() [which is failing
on x86_64], and Robert Love mentioned converting the affinity
syscalls. I had already done them, so here they are again.
Builds and boots.
Please apply. Patch is to 2.5.65-current.
Thanks,
~Randy
