This is for passing through NVIDIA V100 GPUs on POWER9 systems.
This implements a subdriver for NVIDIA V100 GPU with coherent memory and
NPU/ATS support available in the POWER9 CPU.
1/4 is a preparation for bigger DMA windows.
2/4 is a small cleanup.
Here is the kernel driver:

SLOF changes already went in.
This depends on "pci: Move NVIDIA vendor id to the rest of ids" (posted
separately).
This is based on sha1
1ea6057 Mark Cave-Ayland "mac_newworld: change default NIC to sungem for mac99
machine".
Please comment. Thanks.
Alexey Kardashevskiy (4):
vfio/spapr: Fix indirect levels calculation
vfio/spapr: Rename local systempagesize variable
vfio: Make vfio_get_region_info_cap public
spapr: Support NVIDIA V100 GPU with NVLink2
