This looks fine to me (at least it doesn't break the existing IN/OUT
users), and seems the best solution 4.5 wise:

Acked-by: Roger Pau Monné <roger....@citrix.com>

For 4.6 I think we need to start using a different hvm_io_bitmap for PVH
Dom0 that allows direct access to the IO ports, bypassing the vmexit and
simplifying the code in Xen (this would also fix INS/OUTS). Still not
sure what should be done for PVH DomUs, specially when PVH gains support
for pci-passthrough.

Roger.
