[PATCH v3 0/4] nested vmx: enable VMCS shadowing feature
Changes from v2 to v3:
- Use pfn_to_paddr() to get the address from frame number instead of doing shift directly.
- Remove some unnecessary initialization code and add "static" to vmentry_fields and gpdptr_fields.
- Enable the VMREAD/VMWRITE bitmap only if nested hvm is enabled.
- Use clear_page() to set all 0 to the page instead of memset().
- Use domheap to allocate the

[PATCH RFC v13 00/20] Introduce PVH domU support
This patch series is a reworking of a series developed by Mukesh
Rathor at Oracle. The entirety of the design and development was done
by him; I have only reworked, reorganized, and simplified things in a
way that I think makes more sense. The vast majority of the credit
for this effort therefore goes to him. This version is labelled v13
because it is based on his most recent series, v11.
