Introducing the gen17 CPU model with feature indications
comprising of:

* Concurrent-function facility with subcodes
* More vector extensions
* Ineffective-nonconstrained-transaction facility
* Even more msa crypto extensions
* Additional PLO subfunctions

For reference, see also the kernel part:
https://lore.kernel.org/kvm/20241107152319.77816-1-brueckner@linux.ibm.com/T/#me506dc2ca538aee3cfc13620a48bdb686c459ab0

Changelog v1->v2:
- Linux headers update to Linux 6.13-rc1 as pre-req
  for the Concurrent-function facility
- Added missing CPU feature (group) initialization
  for the msa12 and PLO extensions


Feedback and review is always welcome.  Thanks a lot!

Kind regards,
Hendrik

Is the revised Principals of Operation public yet?
I can only find SA22-7832-13 from 2022.

No, the gen17 POP hasn't been published yet AFAIK.
SA22-7832-13 is for gen16.
