[RFC PATCH 0/9] Bus layer cleanups

[Jeremy Huddleston]

I'm interested in this patch series since I'm working to get Xorg building on darwin and need to get the IOADDRESS type of shared code.  This is a pre-req for Tiago's --enable-pciaccess changes which I've rebased on recent master.

This series still applies except for the following:
[PATCH 5/9] vgahw: Port to pciaccess IO space routines
[PATCH 6/9] pci: Port xf86MapLegacyIO to pciaccess
[PATCH 7/9] linux: Use pci_device_get_parent_bridge instead of open-coding it

Adam, would you mind rebasing these and sending them out again for review?  For now I'm just going to work with Tiago's version which just does s/IOADDRESS/unsigned long/
