Queued patches 1-3, thanks. Paolo
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.
