[v5,0/4] pSeries FORM2 affinity support

Message

Hi,

In this new version, the biggest change is that now we're initializing
NUMA associativity internal data during machine_reset(), instead of
machine_init(), to allow for the guest to switch between FORM1 and
FORM2 during guest reset. All other changes are consequence of this
design change.

Changes from v4:
- former patch 1:
  * dropped, pseries-6.2 machine type is already available
- new patch 1:
  * move numa associativity init to machine reset
- patch 3:
  * avoid resetting associativity data if FORM1 was chosen
- former patch 4:
  * dropped, folded into patch 1
- patch 4 (former 5):
  * move both FORM1 verifications to post-CAS
- v4 link: https://lists.gnu.org/archive/html/qemu-devel/2021-08/msg04860.html
