This commit provides the interfaces for the new UAPI motivated by the
Vulkan API. It allows user mode drivers (UMDs) to:
1) Initialize a GPU virtual address (VA) space via the new
DRM_IOCTL_NOUVEAU_VM_INIT ioctl. UMDs can provide a kernel reserved
VA area.
2) Bind and unbind GPU VA space mappings via the new
DRM_IOCTL_NOUVEAU_VM_BIND ioctl.
3) Execute push buffers with the new DRM_IOCTL_NOUVEAU_EXEC ioctl.
Both, DRM_IOCTL_NOUVEAU_VM_BIND and DRM_IOCTL_NOUVEAU_EXEC support
asynchronous processing with DRM syncobjs as synchronization mechanism.
The default DRM_IOCTL_NOUVEAU_VM_BIND is synchronous processing,
DRM_IOCTL_NOUVEAU_EXEC supports asynchronous processing only.

Exactly, doing any of those will disable the new uAPI entirely if it
wasn't yet initialized. I will add some documentation for this.

kernel_managed / kmd_managed both sounds fine to me. I'm good with
either one.

What will this be used for? I guess it would not be important to be
executed in order with "regular" (non-noop) jobs? Because the only thing
this would tell you is that e.g. for VM_BIND all previous binds
completed, which is what we have syncobjs for.
