Subject[PATCH v2 0/3] Workaround for bus reset on Cavium cn8xxx root ports
Date
I've picked this up from David, keeping his patches but preventing to
probe vfio-pci devices that can't be reset.

Without this series starting qemu with a vfio-pci enabled device
can lead to a kernel panic on Cavium systems, depending on the used
hardware.

Changes to v1 (https://lkml.org/lkml/2017/5/15/934):
- Prevent probing by vfio-pci

David Daney (2):
PCI: Allow PCI_DEV_FLAGS_NO_BUS_RESET to be used on bus device
PCI: Avoid bus reset for Cavium cn8xxx root ports

Jan Glauber (1):
vfio/pci: Don't probe devices that can't be reset
