The "vdev->dev.parent" should be used instead of "vdev->dev" as a device
for which to perform the DMA operation in both
virtio_gpu_cmd_transfer_to_host_2d(3d).
Because the virtio-gpu device "vdev->dev" doesn't really have DMA OPS
assigned to it, but parent (virtio-pci or virtio-mmio) device
"vdev->dev.parent" has. The more, the sgtable in question the code is
trying to sync here was mapped for the parent device (by using its DMA OPS)
previously at:
virtio_gpu_object_shmem_init()->drm_gem_shmem_get_pages_sgt()->
dma_map_sgtable(), so should be synced here for the same parent device.

DRM API requires the DRM's driver to be backed with the device that can
be used for generic DMA operations. The VirtIO-GPU device can't perform
DMA operations if it uses PCI transport because PCI device driver creates
a virtual VirtIO-GPU device that isn't associated with the PCI. Use PCI's
GPU device for the DRM's device instead of the VirtIO-GPU device and drop
DMA-related hacks from the VirtIO-GPU driver.

The plumbing is all here to do this. Since we always use the
default fence context when allocating a fence, this makes no
functional difference.
We can't process just the largest fence id anymore, since it's
it's associated with different timelines. It's fine for fence_id
260 to signal before 259. As such, process each fence_id
individually.

This implements the context initialization ioctl. A list of params
is passed in by userspace, and kernel driver validates them. The
only currently supported param is VIRTGPU_CONTEXT_PARAM_CAPSET_ID.
If the context has already been initialized, -EEXIST is returned.
This happens after Linux userspace does dumb_create + followed by
opening the Mesa virgl driver with the same virtgpu instance.
However, for most applications, 3D contexts will be explicitly
initialized when the feature is available.

When kmem_cache_zalloc in virtio_gpu_get_vbuf fails, it will return
an error code. But none of its callers checks this error code, and
a core dump will take place.
Considering many of its callers can't handle such error, I add
a __GFP_NOFAIL flag when calling kmem_cache_zalloc to make sure
it won't fail, and delete those unused error handlings.

The old transfer ioctls may work on blob resources, and there is no
TRANSFER_BLOB hypercall now for simplicity.
The guest may have a image view on the blob resources such that the
stride is not equal to width * bytes_per_pixel.
For host-only blobs, we can repurpose the transfer ioctls to synchronize
caches as well. For guest-only blobs, these operations are undefined
for now so leave them out.
Also, with seamless Wayland integration between guest/host looking
increasingly attractive, it also makes sense to keep track of
one value for stride.

The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the dma_map_sg().
struct sg_table is a common structure used for describing a non-contiguous
memory buffer, used commonly in the DRM and graphics subsystems. It
consists of a scatterlist with memory pages and DMA addresses (sgl entry),
as well as the number of scatterlist entries: CPU pages (orig_nents entry)
and DMA mapped pages (nents entry).
It turned out that it was a common mistake to misuse nents and orig_nents
entries, calling DMA-mapping functions with a wrong number of entries or
ignoring the number of mapped entries returned by the dma_map_sg()
function.
To avoid such issues, lets use a common dma-mapping wrappers operating
directly on the struct sg_table objects and use scatterlist page
iterators where possible. This, almost always, hides references to the
nents and orig_nents entries, making the code robust, easier to follow
and copy/paste safe.
