Hi,

This is the third iteration to improve handling of the 64-bit
attribute on non-prefetchable host bridge ranges. Previous version can
be found at [0][1].

This version is a small update over the previous version - changelog
below. If there is no futher feedback on the patches, please consider
merging them.

Thanks,
Punit

Changes:
v3:
* Improved commit log for clarity (Patch 1)
* Added Tested-by tags

v2:
* Check ranges PCI / bus addresses rather than CPU addresses
* (new) Restrict 32-bit size warnings on ranges that don't have the 64-bit attribute set
* Refactor the 32-bit size warning to the range parsing loop. This
  change also prints the warnings right after the window mappings are
  logged.
