[Qemu-ppc] [PATCH qemu v2 0/4] spapr_pci, vfio: NVIDIA V100 + POWER9 passthrough

[Alexey Kardashevskiy]

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.
