So you can share your CPs from non-Linux-only partitions with your
Linux-only partition, rather than buying a new CPU.  (It's a money math
problem.)

No.

Yes.

I'm not sure I understand your question.  IFLs are available to both kinds
of partitions.  But regardless of the type of partition, you cannot mix
IFLs with other processor types within a single partition.
