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
