Add sysfs interface for each vduse virtqueue to
get/set the affinity for irq callback. This might
be useful for performance tuning when the irq callback
affinity mask contains more than one CPU.

Since virtio-vdpa bus driver already support interrupt
affinity spreading mechanism, let's implement the
set_vq_affinity callback to bring it to vduse device.
After we get the virtqueue's affinity, we can spread
IRQs between CPUs in the affinity mask, in a round-robin
manner, to run the irq callback.

To support interrupt affinity spreading mechanism,
this makes use of group_cpus_evenly() to create
an irq callback affinity mask for each virtqueue
of vdpa device. Then we will unify set_vq_affinity
callback to pass the affinity to the vdpa device driver.

Extend the possible list for features that can be supported by firmware.
Note that different versions of firmware may or may not support these
features. The driver is made aware of them by querying the firmware.
While doing this, improve the code so we use enum names instead of hard
coded numerical values.
The new features supported by the driver are the following:
VIRTIO_NET_F_MRG_RXBUF
VIRTIO_NET_F_HOST_ECN
VIRTIO_NET_F_GUEST_ECN
VIRTIO_NET_F_GUEST_TSO6
VIRTIO_NET_F_GUEST_TSO4

Following patch adds driver support for VIRTIO_NET_F_MRG_RXBUF.
Current firmware versions show degradation in packet rate when using
MRG_RXBUF. Users who favor memory saving over packet rate could enable
this feature but we want to keep it off by default.
One can still enable it when creating the vdpa device using vdpa tool by
providing features that include it.
For example:
$ vdpa dev add name vdpa0 mgmtdev pci/0000:86:00.2 device_features 0x300cb982b

According to the Virtio Specification, the Queue Size parameter of a
virtqueue corresponds to the maximum number of descriptors in that
queue, and it does not have to be a power of 2 for packed virtqueues.
However, the virtio_pci_modern driver enforced a power of 2 check for
virtqueue sizes, which is unnecessary and restrictive for packed
virtuqueue.
Split virtqueue still needs to check the virtqueue size is power_of_2
which has been done in vring_alloc_queue_split of the virtio_ring layer.
To validate this change, we tested various virtqueue sizes for packed
rings, including 128, 256, 512, 100, 200, 500, and 1000, with
CONFIG_PAGE_POISONING enabled, and all tests passed successfully.

We on longer need to hold the vhost_scsi_mutex the entire time we
set/clear the endpoint. The tv_tpg_mutex handles tpg accesses not related
to the tpg list, the port link/unlink functions use the tv_tpg_mutex while
accessing the tpg->vhost_scsi pointer, vhost_scsi_do_plug will no longer
queue events after the virtqueue's backend has been cleared and flushed,
and we don't drop our refcount to the tpg until after we have stopped
cmds and wait for outstanding cmds to complete.
This moves the vhost_scsi_mutex use to it's documented use of being used
to access the tpg list. We then don't need to hold it while a flush is
being performed causing other device's vhost_scsi_set_endpoint
and vhost_scsi_make_tpg/vhost_scsi_drop_tpg calls to have to wait on a
flakey device.

We are using the vhost_scsi_mutex to make sure vhost_scsi_port_link and
vhost_scsi_port_unlink see if vhost_scsi_clear_endpoint has cleared
tpg->vhost_scsi and it can't be freed while they are using.
However, we currently set the tpg->vhost_scsi pointer while holding
tv_tpg_mutex. So, we can just hold that while calling
vhost_scsi_hotplug/hotunplug. We then don't need to hold the
vhost_scsi_mutex while vhost_scsi_clear_endpoint is holding it and doing
a flush which could cause the LUN map/unmap to have to wait on another
device's flush.

We currenly hold the vhost_scsi_mutex while clearing the endpoint and
while performing vhost_scsi_do_plug, so tpg->vhost_scsi can't be freed
from uder us, and to make sure anything queued is handled by the
full call in vhost_scsi_clear_endpoint.
This patch removes the need for the vhost_scsi_mutex for the latter
case. In the next patches, we won't hold the vhost_scsi_mutex while
flushing so this patch adds a check for the clearing of the virtqueue
from vhost_scsi_clear_endpoint. We then know that once
vhost_scsi_clear_endpoint has cleared the backend that no new events
will be queued, and the flush after the vhost_vq_set_backend(vq, NULL)
call will see everything that's been queued to that point. So the flush
will then handle all events without the need for the vhost_scsi_mutex.

We don't need the device mutex in vhost_scsi_do_plug because:
1. we have the vhost_scsi_mutex so the tpg->vhost_scsi pointer will not
change on us and the vhost_scsi can't be freed from under us if it was
set.
2. vhost_scsi_clear_endpoint will stop the virtqueues and flush them while
holding the vhost_scsi_mutex so we know once vhost_scsi_clear_endpoint
has completed that vhost_scsi_do_plug can't send new events and any
queued ones have completed.
So this patch drops the device mutex use in vhost_scsi_do_plug.

We currently hold the vhost_scsi_mutex the entire time we are running
vhost_scsi_clear_endpoint. One of the reasons for this is that it prevents
userspace from being able to free the se_tpg from under us after we have
called target_undepend_item. However, it forces management operations for
for other devices to have to wait on a flakey device's:
vhost_scsi_clear_endpoint -> vhost_scsi_flush()
call which can which can take a long time.
This moves the target_undepend_item call and the tpg unsetup code to after
we have stopped new IO from starting up and after we have waited on
running IO. We can then release our refcount on the tpg and session
knowing our device is no longer accessing them. We can then drop the
vhost_scsi_mutex use during thee flush call in later patches in this set,
when we have removed other reasons for holding it.

According to kernel coding style [1], defining inline functions is not
necessary and beneficial for simple functions. Hence clean up the code
by removing the inline keyword.
It is verified with GCC 12.2.0, the generated code with/without inline
is same. Additionally tested with pktgen and iperf, and verified the
result, the pps test results are the same in the cases of with/without
inline.
Iperf and pps of pktgen for virtio-net didn't change before and after
the change.

Current code ignores link state updates if VIRTIO_NET_F_STATUS was not
negotiated. However, link state updates could be received before feature
negotiation was completed , therefore causing link state events to be
lost, possibly leaving the link state down.
Modify the code so link state notifier is registered after DRIVER_OK was
negotiated and carry the registration only if
VIRTIO_NET_F_STATUS was negotiated. Unregister the notifier when the
device is reset.

Since commit 05e96e96a315 ("kbuild: use git-archive for source package
creation"), a source tarball is created in two steps; create *.tar file
then compress it. I split the compression as a separate rule because I
just thought 'git archive' supported only gzip.
For other compression algorithms, I could pipe the two commands:
$ git archive HEAD | xz > linux.tar.xz
I read git-archive(1) carefully, and I realized GIT had provided a
more elegant way:
$ git -c tar.tar.xz.command=xz archive -o linux.tar.xz HEAD
This commit uses 'tar.tar.*.command' configuration to specify the
compression backend so we can compress a source tarball on-the-fly.
GIT commit 767cf4579f0e ("archive: implement configurable tar filters")
is more than a decade old, so it should be available on almost all build
environments.

Forwarding variadic argument lists can't be done by passing a va_list
to a function with signature foo(...) (as panic() has). It ends up
interpreting the va_list itself as a single argument instead of
iterating it. printf() happily accepts it of course, leading to corrupt
output.
Convert panic_show_mem() to a macro to allow forwarding the arguments.
The function is trivial enough that it's easier than trying to introduce
a vpanic() variant.

Similar to commit 4c9d410f32b3 ("initramfs: Check timestamp to prevent
broken cpio archive"), except asserts that the timestamp is
non-negative. This can happen when the KBUILD_BUILD_TIMESTAMP is a value
before UNIX epoch, which may be set when making reproducible builds that
don't want to look like they use a valid date.
While support for dates before 1970 might not be supported, this is more
about preventing undetected CPIO corruption. The printf's use a minimum
length format specifier, and will happily make the field longer than 8
characters if they need to.

Pull sound fixes from Takashi Iwai:
"A collection of small fixes.
At this time, quite a few fixes for the old PCI drivers are found.
Although they are not regression fixes, I took these as they are
materials for stable kernels.
In addition, a couple of regression fixes and another couple of
HD-audio quirks are included"

Pull rdma fixes from Jason Gunthorpe:
"We had a fairly slow cycle on the rc side this time, here are the
accumulated fixes, mostly in drivers:
- irdma should not generate extra completions during flushing
- Fix several memory leaks
- Do not get confused in irdma's iwarp mode if IPv6 is present
- Correct a link speed calculation in mlx5
- Increase the EQ/WQ limits on erdma as they are too small for big
applications
- Use the right math for erdma's inline mtt feature
- Make erdma probing more robust to boot time ordering differences
- Fix a KMSAN crash in CMA due to uninitialized qkey"

So far io_req_complete_post() only covers DEFER_TASKRUN by completing
request via task work when the request is completed from IOWQ.
However, uring command could be completed from any context, and if io
uring is setup with DEFER_TASKRUN, the command is required to be
completed from current context, otherwise wait on IORING_ENTER_GETEVENTS
can't be wakeup, and may hang forever.
The issue can be observed on removing ublk device, but turns out it is
one generic issue for uring command & DEFER_TASKRUN, so solve it in
io_uring core code.

Use of keep-alive (KAE) has resulted in loss of audio on some A750/770
cards as the transition from keep-alive to stream playback is not
working as expected. As there is limited benefit of the new KAE mode
on discrete cards, revert back to older silent-stream implementation
on these systems.
