[Qemu-devel] [PATCH qemu] target-ppc: Add PVR for POWER8NVL processor

[Alexey Kardashevskiy]

This adds a new POWER8+NVLink CPU PVR which core is identical to POWER8
but has a different PVR. The only available machine now has PVR
pvr 004c 0100 so this defines "POWER8NVL" alias as v1.0.

The corresponding kernel commit is
https://github.com/torvalds/linux/commit/ddee09c099c3
"powerpc: Add PVR for POWER8NVL processor"
