[RFC 0/3] powerpc/pseries: Remap hw to kernel cpu indexes

Define and apply new interface to map hardware-specific powerpc cpu
ids to a kernel specific range of cpu values.  Mapping is intended
to prevent confusion within the kernel about the cpu+node mapping,
and the changes in configuration that may happen due to powerpc LPAR
migration or other associativity changes during the lifetime of a
system.  These interfaces exchange the thread_index provided by the
'ibm,ppc-interrupt-server#s' properties, for an internal index to
be used by kernel scheduling interfaces.
