A feature like `xl cpupool-biglittle-split' can still be interesting,

"cpupool-cluster-split" maybe a better name?

You seem to assume that a cluster, from the MPIDR point of view, can only contain the same set of CPUs. I don't think this is part of the architecture, so this may not be true in the future.

completely orthogonally and independently from the affinity based work,
and this series looks like it can be used to implement that. :-)

Agree. All pcpus default can be assigned into cpupool0 based on the affinity 

What do you mean by affinity? From MPIDR?

We could add one like "cpupool-numa-split" to split different classes cpu
into different cpupools.
