[libvirt] [PATCH v3 0/4] PPC64 support for NVIDIA V100 GPU with NVLink2 passthrough

[Daniel Henrique Barboza]

This series includes Libvirt support for a new QEMU feature for
the spapr (PPC64) machine, NVIDIA V100 + P9 passthrough. Refer to
[1] for the version 3 of this feature (same version used as a reference
for this series).


Changes in v3:
- added a new patch (patch 2) that isolates the PPC64 exclusive
code to calculate the memLockLimit (suggested by Erik Skultety)
- fixed 'make syntax-check' errors across all patches
- v2 can be found at [2]
