As far as I understand, calling a subset of online CPUs that is not all or

With cpusets and isolation etc. it is the normal case.
Oh really? Coming from what callers?

The isolation work is not merged yet, but it will essentially need
to turn a lot of the _call_function()s into _call_function_mask()

kvm is also a heavy user of smp_call_function_mask(); if you run multiple smp guests you'll see plenty of disjoint smp_call_function_mask()s.
