Arnd,

Please pull io.h PCI clean-up series. As you suggested, lets get it in
next for test and decide later if to apply it for 3.6 or wait.

BTW, I'll have sporadic email access over the next 2 weeks.

Pulled into staging/io-cleanup-pci, and I added the introductory
text from your patch series as a merge changeset comment.

Thanks for this great series, I hope we can make it for this merge window.
