Gaah. These emails always happen at the most inconvenient time.

Maybe we should just try that patch in

   https://bugzilla.kernel.org/show_bug.cgi?id=41622#c17

but it really needs to happen early in a merge window. We didn't do
that for 3.2, maybe we can do it for 3.6?

Bjorn, what do you think? Sizing up transparent bridges really is a
bit unnecessary.

Although I really don't see what the difference there is any more.
Yinghai noticed that the prefetchability of the cardbus bridge
changed, but the commit that changed that apparently made no
difference. What other changes does the transparent bridge sizing
cause?
