With one worker we will always send the scsi cmd responses then send the
TMF rsp, because LIO will always complete the scsi cmds first then call
into us to send the TMF response.
With multiple workers, the IO vq workers could be running while the
TMF/ctl vq worker is running so this has us do a flush before completing
the TMF to make sure cmds are completed when it's work is later queued
and run.

This patch separates the scsi cmd completion code paths so we can complete
cmds based on their vq instead of having all cmds complete on the same
worker/CPU. This will be useful with the next patches that allow us to
create mulitple worker threads and bind them to different vqs, and we can
have completions running on different threads/CPUs.

vsock can start queueing work after VHOST_VSOCK_SET_GUEST_CID, so
after we have called vhost_worker_create it can be calling
vhost_work_queue and trying to access the vhost worker/task. If
vhost_dev_alloc_iovecs fails, then vhost_worker_free could free
the worker/task from under vsock.
This moves vhost_worker_create to the end of vhost_dev_set_owner
where we know we can no longer fail in that path. If it fails
after the VHOST_SET_OWNER and userspace closes the device, then
the normal vsock release handling will do the right thing.

Add support for generation of interrupts from the device directly to the
VM to the VCPU thus avoiding the overhead on the host CPU.
When supported, the driver will attempt to allocate vectors for each
data virtqueue. If a vector for a virtqueue cannot be provided it will
use the QP mode where notifications go through the driver.
In addition, we add a shutdown callback to make sure allocated
interrupts are released in case of shutdown to allow clean shutdown.

To add a bit of vendor flexibility with various virtio based devices,
allow the caller to check for a different device id. This adds a function
pointer field to struct virtio_pci_modern_device to specify an override
device id check. If defined by the driver, this function will be called
to check that the PCI device is the vendor's expected device, and will
return the found device id to be stored in mdev->id.device. This allows
vendors with alternative vendor device ids to use this library on their
own device BAR.

Improve the size of the virtio_pci_device structure, which is commonly
used to represent a virtio PCI device. A given virtio PCI device can
either of legacy type or modern type, with the
struct virtio_pci_legacy_device occupying 32 bytes and the
struct virtio_pci_modern_device occupying 88 bytes. Make them a union,
thereby save 32 bytes of memory as shown by the pahole tool. This
improvement is particularly beneficial when dealing with numerous
devices, as it helps conserve memory resources.
Before the modification, pahole tool reported the following:
struct virtio_pci_device {
[...]
struct virtio_pci_legacy_device ldev; /* 824 32 */
/* --- cacheline 13 boundary (832 bytes) was 24 bytes ago --- */
struct virtio_pci_modern_device mdev; /* 856 88 */
/* XXX last struct has 4 bytes of padding */
[...]
/* size: 1056, cachelines: 17, members: 19 */
[...]
};
After the modification, pahole tool reported the following:
struct virtio_pci_device {
[...]
union {
struct virtio_pci_legacy_device ldev; /* 824 32 */
struct virtio_pci_modern_device mdev; /* 824 88 */
}; /* 824 88 */
[...]

The final bug fixes for Qualcomm and Rockchips came in, all of them
for devicetree files:
- Devices on Qualcomm SC7180/SC7280 that are cache coherent are now
marked so correctly to fix a regression after a change in kernel behavior.
- Rockchips has a few minor changes for correctness of regulator and cache
properties, as well as fixes for incorrect behavior of the RK3568 PCI
controller and reset pins on two boards.

"Unfortunately the recent u32 overflow fix was not complete, there was
one conversion left, assertion not triggered by my tests but caught by
Qu's fstests case.
The "cleanup for later" has been promoted to a proper fix and wraps
all uses of the stripe left shift so the diffstat has grown but leaves
no potentially problematic uses.
We should have done it that way before, sorry"
