[PATCH v8 0/7] pSeries FORM2 affinity support

[Daniel Henrique Barboza]

Hi,

This new version contains changes made in patch 7 after looking more
carefully in the auto-generated NUMA node issue. I also took the
opportunity to make a change that Greg requested in an earlier
review that didn't make to v7.


Changes from v7:
- patch 3:
  * removed redundant 'no FORM2 available yet' comments
- patch 7:
  * removed the unneeded handling of numa_state->num_nodes
- v7 link: https://lists.gnu.org/archive/html/qemu-devel/2021-09/msg04156.html

Changes from v6:
- patch 1:
  * added Greg's r-b
- patch 2:
  * added the missing NUMA nodes number check
  * added Greg's r-b
- patch 3 (former patch 4):
  * no changes.
- former patch 3 (associativity_reset()): dropped
- patch 4 (new):
  * added get_associativity()
  * do not allocate FORM1_assoc_array in the heap
- patch 5:
  * fixed typo
  * added new check function to be called in CAS
- patch 6:
  * do not allocate FORM2_assoc_array in the heap
- patch 7 (new):
  * FORM2 fixes to handle the implicit added QEMU NUMA node when there's
  no NUMA node added by the user.
