Subject[PATCH 0/5] AVIC bugfixes and workarounds
Date
Hi!

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.

Best regards,
Maxim Levitsky
