Hi Sagi,
did you have a chance to look on Israel's and mine fixes that we 
attached to the first thread ?

there are few issues with this approach. For example in case you don't 
have a "free" cpu in the mask for Qi and you take cpu from Qi+j mask.

Also in case we have a non-symetrical affinity for 2 queues e.g. and the 
system has 32 cpus, the mapping is 16 for each (and not according to the 
user affinity...).

-Max.
