[PATCH v3 0/8] VT-d Native Shared virtual memory cleanup and fixes

From: Jacob Pan
Date: Tue Nov 19 2019 - 12:52:02 EST


Mostly extracted from nested SVA/SVM series based on review comments of v7.
https://lkml.org/lkml/2019/10/24/852

This series also adds a few important fixes for native use of SVA. Nested
SVA new code will be submitted separately as a smaller set. Based on the
core branch of IOMMU tree staged for v5.5, where common APIs for vSVA were
applied.

Changelog:
V3
- Squashed 1/10 & 2/10
- Deleted "8/10 Fix PASID cache flush" from this series
- Addressed reviews from Eric Auger and Baolu
V2
- Coding style fixes based on Baolu's input, no functional change
- Added Acked-by tags.

Thanks,

Jacob
