SOF driver will load required function topologies dynamically. However,
we prefer using the monolithic topology. Add a flag to allow user not
using the function topologies.

Allow userspace to pass a per-I/O write stream in the SQE:
__u8 write_stream;
The __u8 type matches the size the filesystems and block layer support.
Application can query the supported values from the block devices
max_write_streams sysfs attribute. Unsupported values are ignored by
file operations that do not support write streams or rejected with an
error by those that support them.

scheduler's ->exit() is called with queue frozen and elevator lock is held, and
wbt_enable_default() can't be called with queue frozen, otherwise the
following lockdep warning is triggered:
#6 (&q->rq_qos_mutex){+.+.}-{4:4}:
#5 (&eq->sysfs_lock){+.+.}-{4:4}:
#4 (&q->elevator_lock){+.+.}-{4:4}:

#1 (&sb->s_type->i_mutex_key#3){+.+.}-{4:4}:

Fix the issue by moving wbt_enable_default() out of bfq's exit(), and
call it from elevator_change_done().
Meantime add disk->rqos_state_mutex for covering wbt state change, which
matches the purpose more than ->elevator_lock.

Add new helper disable_elv_switch() and new flag QUEUE_FLAG_NO_ELV_SWITCH
for disabling elevator switch before deleting disk:
- originally flag QUEUE_FLAG_REGISTERED is added for preventing elevator
switch during removing disk, but this flag has been used widely for
other purposes, so add one new flag for disabling elevator switch only
- for avoiding deadlock risk, we have to move elevator queue
register/unregister out of elevator lock and queue freeze, which will be
done in next patch. However, this way adds small race window between elevator
switch and deleting ->queue_kobj, in which elevator queue register/unregister
could be run concurrently. The added helper will be used for avoiding the race
in the following patch.
- drain in-progress elevator switch before deleting disk

Both adding/deleting disk code are reader of `nr_hw_queues`, so we can't
allow them in-progress when updating nr_hw_queues, kernel panic and
kasan has been reported in [1].
Prevent adding/deleting disk during updating nr_hw_queues by adding
rw_semaphore to tagset, write lock is grabbed in blk_mq_update_nr_hw_queues(),
and read lock is acquired when adding/deleting disk.
Also mark GFP_NOIO allocation scope for adding/deleting disk because
blk_mq_update_nr_hw_queues() is part of some driver's error handler.
This way avoids lot of trouble.

v4l2_find_nearest_size() returns a mode from sensor driver's mode list
that is a best match width and height wise for the sensor. Some drivers
have different set of available modes depending on the number of lanes.
While this could be handled within a driver by providing different lists
of modes, provide a helper v4l2_find_nearest_size_conditional() to ignore
modes that aren't available.
Also use size_t for the array index and remove extra commas while at it.

dma_iova_alloc()
for (page in range)
dma_iova_link_next(...)
dma_iova_sync(...)
else
/* Fallback to legacy map pages */
for (all pages)
dma_map_page(...)
In unmap path:

The existing .map_pages() callback provides both allocating of IOVA
and linking DMA pages. That combination works great for most of the
callers who use it in control paths, but is less effective in fast
paths where there may be multiple calls to map_page().
These advanced callers already manage their data in some sort of
database and can perform IOVA allocation in advance, leaving range
linkage operation to be in fast path.
Provide an interface to allocate/deallocate IOVA and next patch
link/unlink DMA ranges to that specific IOVA.
In the new API a DMA mapping transaction is identified by a
struct dma_iova_state, which holds some recomputed information
for the transaction which does not change for each page being
mapped, so add a check if IOVA can be used for the specific
transaction.
The API is exported from dma-iommu as it is the only implementation
supported, the namespace is clearly different from iommu_* functions
which are not allowed to be used. This code layout allows us to save
function call per API call used in datapath as well as a lot of boilerplate
code.

For the upcoming IOVA-based DMA API we want to batch the
ops->iotlb_sync_map() call after mapping multiple IOVAs from
dma-iommu without having a scatterlist. Improve the API.
Add a wrapper for the map_sync as iommu_sync_map() so that callers
don't need to poke into the methods directly.
Formalize __iommu_map() into iommu_map_nosync() which requires the
caller to call iommu_sync_map() after all maps are completed.
Refactor the existing sanity checks from all the different layers
into iommu_map_nosync().

To support the upcoming non-scatterlist mapping helpers, we need to go
back to have them called outside of the DMA API. Thus move them out of
dma-map-ops.h, which is only for DMA API implementations to pci-p2pdma.h,
which is for driver use.
Note that the core helper is still not exported as the mapping is
expected to be done only by very highlevel subsystem code at least for
now.

The current scheme with a single helper to determine the P2P status
and map a scatterlist segment force users to always use the map_sg
helper to DMA map, which we're trying to get away from because they
are very cache inefficient.
Refactor the code so that there is a single helper that checks the P2P
state for a page, including the result that it is not a P2P page to
simplify the callers, and a second one to perform the address translation
for a bus mapped P2P transfer that does not depend on the scatterlist
structure.

Merge series from Philipp Stanner <phasta@kernel.org>:
A year ago we spent quite some work trying to get PCI into better shape.
Some pci_ functions can be sometimes managed with devres, which is
obviously bad. We want to provide an obvious API, where pci_ functions
are never, and pcim_ functions are always managed.
Thus, everyone enabling his device with pcim_enable_device() must be
ported to pcim_ functions. Porting all users will later enable us to
significantly simplify parts of the PCI subsystem. See here [1] for
details.
This patch series does that for sound.
Feel free to squash the commits as you see fit.

Drivers with "memory-region" properties currently have to do their own
parsing of "memory-region" properties. The result is all the drivers
have similar patterns of a call to parse "memory-region" and then get
the region's address and size. As this is a standard property, it should
have common functions for drivers to use. Add new functions to count the
number of regions and retrieve the region's address as a resource.

Certain clocks on the RK3576 are additionally essentially "gated" behind
some bit toggles in the IOC GRF range. Downstream ungates these by
adding a separate clock driver that maps over the GRF range and leaks
their implementation of this into the DT.
Instead, define some new clock IDs for these, so that consumers of these
types of clocks can properly articulate which clock they're using, so
that we can then add them to the clock driver for SoCs that need them.

2) Fixed a crash when a bpf qdisc is set in
the net.core.default_qdisc, from Amery Hung.
3) A few other fixes in the bpf qdisc, from Amery Hung.
- Always call qdisc_watchdog_init() in the .init prologue such that
the .reset/.destroy epilogue can always call qdisc_watchdog_cancel()
without issue.
- bpf_qdisc_init_prologue() was incorrectly returning an error
when the bpf qdisc is set as the default_qdisc and the mq is creating
the default_qdisc. It is now fixed.

Export a new helper function `dma_fence_dedup_array()` that sorts
an array of dma_fence pointers by context, then deduplicates the array
by retaining only the most recent fence per context.
This utility is useful when merging or optimizing sets of fences where
redundant entries from the same context can be pruned. The operation is
performed in-place and releases references to dropped fences using
dma_fence_put().
v2: - Export this code from dma-fence-unwrap.c(by Christian).
v3: - To split this in a dma_buf patch and amd userq patch(by Sunil).
- No need to add a new function just re-use existing(by Christian).
v4: - Export dma_fence_dedub_array and use it(by Christian).

Upon RQ destruction if the firmware command fails which is the
last resource to be destroyed some SW resources were already cleaned
regardless of the failure.
Now properly rollback the object to its original state upon such failure.
In order to avoid a use-after free in case someone tries to destroy the
object again, which results in the following kernel trace:
refcount_t: underflow; use-after-free.

The zynqmp-sha partial block was based on an old design of the
partial block API where the leftover calculation was done in the
Crypto API. As the leftover calculation is now done by the
algorithm, fix this by passing the partial blocks to the fallback.
Also zero the stack descriptors.
