When running syzkaller with the newly reintroduced signed integer wrap sanitizer we encounter this splat:

Historically, the signed integer overflow sanitizer did not work in the kernel due to its interaction with `-fwrapv` but this has since been changed [1] in the newest version of Clang. It was re-enabled in the kernel with Commit 557f8c582a9ba8ab ("ubsan: Reintroduce signed overflow sanitizer").
Let's rearrange the check to not perform any arithmetic, thus not tripping the sanitizer.

[ Upstream commit eb853413d02c8d9b27942429b261a9eef228f005 ]
Small APUs(i.e., consumer, embedded products) usually have a small carveout device memory which can't satisfy most compute workloads memory allocation requirements.
We can't even run a Basic MNIST Example with a default 512MB carveout. https://github.com/pytorch/examples/tree/main/mnist. Error Log:
"torch.cuda.OutOfMemoryError: HIP out of memory. Tried to allocate 84.00 MiB. GPU 0 has a total capacity of 512.00 MiB of which 0 bytes is free. Of the allocated memory 103.83 MiB is allocated by PyTorch, and 22.17 MiB is reserved by PyTorch but unallocated"
Though we can change BIOS settings to enlarge carveout size, which is inflexible and may bring complaint. On the other hand, the memory resource can't be effectively used between host and device.
The solution is MI300A approach, i.e., let VRAM allocations go to GTT. Then device and host can flexibly and effectively share memory resource.
v2: Report local_mem_size_private as 0. (Felix)

Currently, we can try to queue an event's work before the vhost_task is created. When this happens we just drop it in vhost_scsi_do_plug before even calling vhost_vq_work_queue. During a device shutdown we do the same thing after vhost_scsi_clear_endpoint has cleared the backends.
In the next patches we will be able to kill the vhost_task before we have cleared the endpoint. In that case, vhost_vq_work_queue can fail and we will leak the event's memory. This has handle the failure by just freeing the event. This is safe to do, because vhost_vq_work_queue will only return failure for us when the vhost_task is killed and so userspace will not be able to handle events if we sent them.
