I suppose if RH is going to deploy 3.10 and we aren't going to backport
the multitce patches then there *might* be a case for supporting that
combo specifically... but it's going to be that bad every time we add
a new feature with a kernel counter part or start adding the gazillion
little bits of PAPR that we are still missing ?
