This is another iteration on Yongji's series to force MMIO BARs not to
share pages, which allows direct passthrough instead of QEMU emulation.
The only things I really changed were to add some comments and factor out
the code that requests resize. I also pulled in the IOV patch, which
touches the same code but was posted separately.
These are all on my pci/resource branch, and if all goes well, I plan to
merge these for v4.12.
Changelog v11:
- Include patch to ignore IOV alignment
- Add patches to factor out realignment
- Add comment about "resize" usage
