I'll take a look at 4.4.y and check with Alex if these can be backported or not.
I worked with Alex today.
The commit 523184972b28 doesn't apply because of another missing patch on 4.4.y kernel.
commit ddf9dc0eb531 ("vfio-pci: Virtualize PCIe & AF FLR")
Please apply commit ddf9dc0eb531 ("vfio-pci: Virtualize PCIe & AF FLR") before applying 523184972b28.
commit ddf9dc0eb531 ("vfio-pci: Virtualize PCIe & AF FLR") also fixes a real issue as follows:
"This seems to fix several instance of devices getting into bad states with userspace drivers, like dpdk, running inside a VM."
It would be good to pull both to 4.y.
I'll have to work on cf0d53ba4947 next.
