[Xen-devel] [PATCH 01/22] xen: Don't disable the I/O space

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

From: Alex Nixon <alex.nixon@xxxxxxxxxx>

If a guest domain wants to access PCI devices through the frontend
driver (coming later in the patch series), it will need access to the
I/O space.

[ Impact: Allow for domU IO access, preparing for pci passthrough ]
