If only some of the vCPUs in a HVM DomU, you need to ask for ask for
the on line CPU number, not the expected vCPU number; fCPU can be
used for this.

I'm sorry, but I can't make sense of this description, and hence
can't review the patch.

Yeah, I'm wondering what the f stands for.

This was code to work around a bug.  I do not see how I got the result I did and since that DomU (and old xen version) is long gone, I will attempt to get a DomU in a similar state and check that this is not need.
