This patch series includes several fixes to AVIC I found while working
on a new version of nested AVIC code.
Also while developing it I realized that a very simple workaround for
AVIC's errata #1235 exists and included it in this patch series as well.
changes since v2:
- added 'fixes' tags
- reworked workaround for avic errata #1235
- dropped iommu patch as it is no longer needed.
Best regards,
Maxim Levitsky

Paolo, I assume you'll take the first three directly for 6.6?
