This patchset defines a denylist of devices in the vfio-pci module and adds the current generation of Intel(R) QuickAssist devices to it as they are not designed to run in an untrusted environment. By default, if a device is in the denylist, the probe of vfio-pci fails. If a user wants to use a device in the denylist, he needs to disable the full denylist providing the option disable_denylist=1 at the load of vfio-pci or specifying that parameter in a config file in /etc/modprobe.d. This series also moves the device ids definitions present in the qat driver to linux/pci_ids.h since they will be shared between the vfio-pci and the qat drivers and replaces the custom ADF_SYSTEM_DEVICE macro with PCI_VDEVICE. The series is applicable to Herbert's tree. Patches 1 to 3 apply also to Alex's tree (next). Patches 4 and 5 are optional and can be applied at a later stage.
