Oh, sorry, I didn't realize that this was so urgent.  I guess I read
"this adds an important capability" in the cover letter and concluded
that it was new functionality.

Anyway, if it's broken, presumably PCI on Keystone *did* work at one
point.  Can you identify the commit that broke it and requires these
fixes, so we can figure out how far the fixes need to be backported?

If I merge it, I would like to get into my for-linus branch and get a
little time in -next before asking Linus to pull it.  The merge window
is a little wrinkle there -- I don't like to add new things to the mix
during the window.  But if it's an important fix we can still get it
in before the final v3.20.
