This is a left over from an earlier version that creates a lot of
complexity for error unwind, particularly for FD uobjects.
The only reason this was done is so that anon_inode_get_file() could be
called with the final fops and a fully setup uobject. Both need to be
setup since unwinding anon_inode_get_file() via fput will call the
driver's release().
Now that the driver does not provide release, we no longer need to worry
about this complicated sequence, simply create the struct file at the
start and allow the core code's release function to deal with the abort
case.
This allows all the confusing error paths around commit to be removed.

FD uobjects have a weird split between the struct file and uobject
world. Simplify this to make them pure uobjects and use a generic release
method for all struct file operations.
This fixes the control flow so that mlx5_cmd_cleanup_async_ctx() is always
called before erasing the linked list contents to make the concurrancy
simpler to understand.
For this to work the uobject destruction must fence anything that it is
cleaning up - the design must not rely on struct file lifetime.
Only deliver_event() relies on the struct file to when adding new events
to the queue, add a is_destroyed check under lock to block it.

dispatch_event_fd() runs from a notifier with minimal locking, and relies
on RCU and a file refcount to keep the uobject and eventfd alive.
As the next patch wants to remove the file_operations release function
from the drivers, re-organize things so that the devx_event_notifier()
path uses the existing RCU to manage the lifetime of the uobject and
eventfd.
Move the refcount puts to a call_rcu so that the objects are guaranteed to
exist and remove the indirect file refcount.

After device disassociation the uapi_objects are destroyed and freed,
however it is still possible that core code can be holding a kref on the
uobject. When it finally goes to uverbs_uobject_free() via the kref_put()
it can trigger a use-after-free on the uapi_object.
Since needs_kfree_rcu is a micro optimization that only benefits file
uobjects, just get rid of it. There is no harm in using kfree_rcu even if
it isn't required, and the number of involved objects is small.

There are several algorithms available for raid6 to generate xor and syndrome
parity, including basic int1, int2 ... int32 and SIMD optimized implementation
like sse and neon. To test and choose the best algorithms at the initial
stage, we need provide enough disk data to feed the algorithms. However, the
disk number we provided depends on page size and gfmul table, seeing bellow:
const int disks = (65536/PAGE_SIZE) + 2;
So when come to 64K PAGE_SIZE, there is only one data disk plus 2 parity disk,
as a result the chosed algorithm is not reliable. For example, on my arm64
machine with 64K page enabled, it will choose intx32 as the best one, although
the NEON implementation is better.
This patch tries to fix the problem by defining a constant raid6 disk number to
supporting arbitrary page size.

Add support for capability register, which is used for detection of the
actual number of interrupt capable components within the particular
group, supported by the specific system.
Such components could be for example the number of power units and
interrupts related to these units.
The motivation is to avoid adding a new code in the future in order to
distinct between the systems type supported different number of the
components like power supplies, FANs, ASICs, line cards.

Extra Boot Config (XBC) allows admin to pass a tree-structured
boot configuration file when boot up the kernel. This extends
the kernel command line in an efficient way.
Boot config will contain some key-value commands, e.g.
key.word = value1
another.key.word = value2
It can fold same keys with braces, also you can write array
data. For example,
key {
word1 {
setting1 = data
setting2
}
word2.array = "val1", "val2"
}
User can access these key-value pair and tree structure via
SKC APIs.

As there's two struct ring_buffers in the kernel, it causes some confusion.
The other one being the perf ring buffer. It was agreed upon that as neither
of the ring buffers are generic enough to be used globally, they should be
renamed as:
perf's ring_buffer -> perf_buffer
ftrace's ring_buffer -> trace_buffer
This implements the changes to the ring buffer that ftrace uses.

As we are working to remove the generic "ring_buffer" name that is used by
both tracing and perf, the ring_buffer name for tracing will be renamed to
trace_buffer, and perf's ring buffer will be renamed to perf_buffer.
As there already exists a trace_buffer that is used by the trace_arrays, it
needs to be first renamed to array_buffer.

eBPF requires needing to know the size of the perf ring buffer structure.
But it unfortunately has the same name as the generic ring buffer used by
tracing and oprofile. To make it less ambiguous, rename the perf ring buffer
structure to "perf_buffer".
As other parts of the ring buffer code has "perf_" as the prefix, it only
makes sense to give the ring buffer the "perf_" prefix as well.

For SoundWire support, we added a 'link_mask' to describe the PCB hardware
layout. This helped form a signature that can be used as a first-order way
of detecting the hardware and selecting the machine driver.
The concept of link_mask is however not enough. Some BIOS enable all links,
even when there are no devices physically connected. We can also see
variations with multiple devices attached on one link, or different types
of devices connected on the same link. To accurately represent the
hardware, we need to build static tables where each link exposes a list of
expected devices represented by the 64-bit _ADR field (which uniquely
identifies each device).
The new 'links' field is optional when the link_mask is sufficient to
represent a platform in a unique way.
The existing mechanism to support I2C devices is left as is, it'd be too
invasive to change the existing support for _HID and the notion of link is
not relevant either.

In the commit 8e85def5723e ("ALSA: hda: enable regmap internal
locking"), we re-enabled the regmap lock due to the reported
regression that showed the possible concurrent accesses. It was a
temporary workaround, and there are still a few opened races even
after the revert. In this patch, we cover those still opened windows
with a proper mutex lock and disable the regmap internal lock again.
First off, the patch introduces a new snd_hdac_device.regmap_lock
mutex that is applied for each snd_hdac_regmap_*() call, including
read, write and update helpers. The mutex is applied carefully so
that it won't block the self-power-up procedure in the helper
function. Also, this assures the protection for the accesses without
regmap, too.
The snd_hdac_regmap_update_raw() is refactored to use the standard
regmap_update_bits_check() function instead of the open-code. The
non-regmap case is still open-coded but it's an easy part. The all
read and write operations are in the single mutex protection, so it's
now race-free.
In addition, a couple of new helper functions are added:
snd_hdac_regmap_update_raw_once() and snd_hdac_regmap_sync(). Both
are called from HD-audio legacy driver. The former is to initialize
the given verb bits but only once when it's not initialized yet. Due
to this condition, the function invokes regcache_cache_only(), and
it's now performed inside the regmap_lock (formerly it was racy) too.
The latter function is for simply invoking regcache_sync() inside the
regmap_lock, which is called from the codec resume call path.
Along with that, the HD-audio codec driver code is slightly modified /
simplified to adapt those new functions.
And finally, snd_hdac_regmap_read_raw(), *_write_raw(), etc are
rewritten with the helper macro. It's just for simplification because
the code logic is identical among all those functions.

The adis library only allows to define a `startup_delay` which for some
devices is enough. However, other devices define different timeouts with
significantly different timings which could lead to devices to not wait
enough time or to wait a lot more than necessary (which is not
efficient). This patch introduces a new timeout struct that must be
passed into `adis_init()`. There are mainly, for now, three timeouts
used. This is also an introductory patch with the goal of refactoring
`adis_initial_startup()`. New driver's (eg: adis16480, adis16460) are
replicating code for the device initial setup. With some changes (being
this the first one) we can pass this to `adis_initial_startup()`.
