lots of "bridge window ... (disabled)" messages

["Luck, Tony" <tony.luck@intel.com>]

Hi Bjorn,

I just booted Linus latest git tree on my Tukwila system. I'm
seeing a lot of bridge windows marked as disabled. Here's the
start of a diff of dmesg output comparing a kernel from last
week to today's kernel (git 01e7770 vs. b72c409):

< pci 0000:00:01.0:   bridge window [mem 0xfff00000 - 000fffff pref] reg reading

   ... many more such diffs.

This is the same system that you helped out with a couple of months
ago that had some issues in _CRS tables with ranges marked as
"consumer".  The BIOS team fixed the one range that was needed
to allow access to my EHCI - but they didn't touch anything else.

Are these new checks related to the same sort of issues in _CRS?
Or is this some other stuff?  I don't appear to have lost access
to any devices in today's kernel.
