[PATCH 0/3] vfio-pci: VGA and legacy MMIO & I/O port access

[Alex Williamson]

This series includes a couple cleanups that I'll target for 3.9 plus
RFC patch 3/3 that adds device regions for legacy I/O and makes use
of the VGA arbiter for enabling VGA assignment.  I know the POWER
guys don't likely care about VGA support, but Alexey, Ben, and David,
I'd appreciate any feedback on the overal incorporation into vfio
given your history with the design.  VGA is still a work in progress
but with this base I'm able to assign a handlful of desktop cards that
I have on hand to a qemu guest using standard builtin VGA drivers.
Thanks,

Alex
