Hi,
We have two pathes to build stage2 mapping for MMIO regions.
Create time's path and stage2 fault path.
Patch#1 removes the creation time's mapping of MMIO regions
Patch#2 tries stage2 block mapping for host device MMIO at fault path
Changelog:
v3:
- Do not need to check memslot boundary in device_rough_page_shift(). (Marc)
Thanks,
Keqian
