I think we don't need this function at all, we can use kzalloc/kzalloc_node directly with cfs_cpt_spread_node call in.

What we do need is obd_cpt_alloc_large similar to how we need obd_alloc_large (I know I still owe you a proper patch with that).
The only differences between the two would then be passing down of the cpt (and it's use) or not.
