[Qemu-devel] [PATCH 0/3] pseries: Reverse behaviour change for older machine types

[David Gibson]

152ef80 "pseries: Rewrite CAS PVR compatibility logic" incorrectly
introduced a guest-visible behaviour change into existing versioned
machine type.  Patch 2/2 corrects this change, while 1/2 is a
preliminary clean up to make that easier.

Unfortunately, this bug is already in the released qemu-2.9.0.  Once
this is ready to merge for master, I'll make a backport to apply for
2.9.1 as well.

Changes since RFC:
 * Corrected serious bug in vector address calculation which would
   have broken all the rest of the CAS process
 * Added a third patch with tracing cleanup
 * Correct error in commit message

David Gibson (3):
  pseries: Split CAS PVR negotiation out into a separate function
  pseries: Restore PVR negotiation logic for pre-2.9 machine types
  pseries: Improve tracing of CPU compatibility negotiation
