[PATCH v4 0/8] amd_iommu: Fixes to align with AMDVi specification

[Alejandro Jimenez <alejandro.j.jimenez@oracle.com>]

Added two new changes based on observations from Ethan. Like the rest of
the fixes in this series, these do not trigger problems today given the
limited feature set supported. Re-tested the series with emulated devices,
VFIO passthrough usage with amd-iommu is not possible since merge of commit
31753d5a336f ("hw/i386/amd_iommu: Fix device setup failure when PT is on.")
regardless of guest kernel iommu mode.

Changes since v3:
- Made an additional change in PATCH 1 with correct encoding for
AMDVI_MAX_GVA_ADDR, adding Ethan as co-author. Dropped Vasant R-b.
- Added patch by Ethan fixing truncation bug.

Thank you,
Alejandro
