Hi Konrad / David,

This series still lacks a resolution on the sysfs /do_flr /reset,
as a result the pci devices are not reset after shutdown of a guest.
(no more pciback 0000:xx:xx.x: restoring config space at offset xxx)

So this series now introduces a regression to 3.16, which causes devices to malfunction 
after a guest reboot or after assigning the devices to another guest.

Apart from that .. i can't resist to remind the other issue with removing pci
devices passed through to HVM guests related to the signaling via xenstore,
described in:
