On reflection I probably should have asked you for a fixes tag and
applied it to net :S

Code specific to Hyper-V guests currently assumes the cpu_possible_mask
is "dense" -- i.e., all bit positions 0 thru (nr_cpu_ids - 1) are set,
with no "holes". Therefore, num_possible_cpus() is assumed to be equal
to nr_cpu_ids.
Per a separate discussion[1], this assumption
