Use the two functions: fdma_alloc_phys() and fdma_dcb_init() for rx
buffer allocation and use the new buffers throughout.
In order to replace the old buffers with the new ones, we have to do the
following refactoring:
- use fdma_alloc_phys() and fdma_dcb_init()
- replace the variables: tx->dma, tx->dcbs and tx->curr_entry
with the equivalents from the FDMA struct.
- add lan966x_fdma_tx_dataptr_cb callback for obtaining the dataptr.
- Initialize FDMA struct values.

I have done a lot of analysis for these type of devices and collaborated
quite a bit with Nick Weihs (author of the first patch submitted for this
including adding samsung_helper.c). More information can be found in the
issue on Github [1] including additional rationale and testing.
The existing implementation includes a large number of equalizer coef
values that are not necessary to actually init and enable the speaker
amps, as well as create a somewhat worse sound profile. Users have
reported "muffled" or "muddy" sound; more information about this including
my analysis of the differences can be found in the linked Github issue.
This patch refactors the "v2" version of ALC298_FIXUP_SAMSUNG_AMP to a much
simpler implementation which removes the new samsung_helper.c, reuses more
of the existing patch_realtek.c, and sends significantly fewer unnecessary
coef values (including removing all of these EQ-specific coef values).
A pcm_playback_hook is used to dynamically enable and disable the speaker
amps only when there will be audio playback; this is to match the behavior
of how the driver for these devices is working in Windows, and is
suspected but not yet tested or confirmed to help with power consumption.
Support for models with 2 speaker amps vs 4 speaker amps is controlled by
a specific quirk name for both types. A new int num_speaker_amps has been
added to alc_spec so that the hooks can know how many speaker amps to
enable or disable. This design was chosen to limit the number of places
that subsystem ids will need to be maintained: like this, they can be
maintained only once in the quirk table and there will not be another
separate list of subsystem ids to maintain elsewhere in the code.
Also updated the quirk name from ALC298_FIXUP_SAMSUNG_AMP2 to
ALC298_FIXUP_SAMSUNG_AMP_V2_.. as this is not a quirk for "Amp #2" on
ALC298 but is instead a different version of how to handle it.
More devices have been added (see Github issue for testing confirmation),
as well as a small cleanup to existing names.

Refactor out the iop binding behavior out of the erofs_fill_symlink
and move erofs_buf into the erofs_read_inode, so that erofs_fill_inode
can only deal with inode operation bindings and can be decoupled from
metabuf operations. This results in better calling conventions.
Note that after this patch, we do not need erofs_buf and ofs as
parameters any more when calling erofs_read_inode as
all the data operations are now included in itself.

Although fscache is still described as "General Filesystem Caching" for
network filesystems and other things such as ISO9660 filesystems, it has
actually become a part of netfslib recently, which was unexpected at the
time when "EROFS over fscache" proposed (2021) since EROFS is entirely a
disk filesystem and the dependency is redundant.
Mark it deprecated and it will be removed after "fanotify pre-content
hooks" lands, which will provide the same functionality for EROFS.

It actually has been around for years: For containers and other sandbox
use cases, there will be thousands (and even more) of authenticated
(sub)images running on the same host, unlike OS images.
Of course, all scenarios can use the same EROFS on-disk format, but
bdev-backed mounts just work well for OS images since golden data is
dumped into real block devices. However, it's somewhat hard for
container runtimes to manage and isolate so many unnecessary virtual
block devices safely and efficiently [1]: they just look like a burden
to orchestrators and file-backed mounts are preferred indeed. There
were already enough attempts such as Incremental FS, the original
ComposeFS and PuzzleFS acting in the same way for immutable fses. As
for current EROFS users, ComposeFS, containerd and Android APEXs will
be directly benefited from it.
On the other hand, previous experimental feature "erofs over fscache"
was once also intended to provide a similar solution (inspired by
Incremental FS discussion [2]), but the following facts show file-backed
mounts will be a better approach:
- Fscache infrastructure has recently been moved into new Netfslib
which is an unexpected dependency to EROFS really, although it
originally claims "it could be used for caching other things such as
ISO9660 filesystems too." [3]
- It takes an unexpectedly long time to upstream Fscache/Cachefiles
enhancements. For example, the failover feature took more than
one year, and the deamonless feature is still far behind now;
- Ongoing HSM "fanotify pre-content hooks" [4] together with this will
perfectly supersede "erofs over fscache" in a simpler way since
developers (mainly containerd folks) could leverage their existing
caching mechanism entirely in userspace instead of strictly following
the predefined in-kernel caching tree hierarchy.
After "fanotify pre-content hooks" lands upstream to provide the same
functionality, "erofs over fscache" will be removed then (as an EROFS
internal improvement and EROFS will not have to bother with on-demand
fetching and/or caching improvements anymore.)

syzbot reported a task hang issue due to a deadlock case where it is
waiting for the folio lock of a cached folio that will be used for
cache I/Os.
After looking into the crafted fuzzed image, I found it's formed with
several overlapped big pclusters as below:
Ext: logical offset | length : physical offset | length
0: 0.. 16384 | 16384 : 151552.. 167936 | 16384
1: 16384.. 32768 | 16384 : 155648.. 172032 | 16384
2: 32768.. 49152 | 16384 : 537223168.. 537239552 | 16384
...
Here, extent 0/1 are physically overlapped although it's entirely
_impossible_ for normal filesystem images generated by mkfs.
First, managed folios containing compressed data will be marked as
up-to-date and then unlocked immediately (unlike in-place folios) when
compressed I/Os are complete. If physical blocks are not submitted in
the incremental order, there should be separate BIOs to avoid dependency
issues. However, the current code mis-arranges z_erofs_fill_bio_vec()
and BIO submission which causes unexpected BIO waits.
Second, managed folios will be connected to their own pclusters for
efficient inter-queries. However, this is somewhat hard to implement
easily if overlapped big pclusters exist. Again, these only appear in
fuzzed images so let's simply fall back to temporary short-lived pages
for correctness.
Additionally, it justifies that referenced managed folios cannot be
truncated for now and reverts part of commit 2080ca1ed3e4 ("erofs: tidy
up `struct z_erofs_bvec`") for simplicity although it shouldn't be any
difference.

ionic: convert Rx queue buffers to use page_pool
Our home-grown buffer management needs to go away and we need to play
nicely with the page_pool infrastructure. This patchset cleans up some
of our API use and converts the Rx traffic queues to use page_pool.
The first few patches are for tidying up things, then a small XDP
configuration refactor, adding page_pool support, and finally adding
support to hot swap an XDP program without having to reconfigure
anything.
The result is code that more closely follows current patterns, as well as
a either a performance boost or equivalent performance as seen with
iperf testing:

Using examples of other driver(s), add the ability to hot-swap an XDP
program without having to reconfigure the queues. To prevent the
q->xdp_prog to be read/written more than once use READ_ONCE() and
WRITE_ONCE() on the q->xdp_prog.
The q->xdp_prog was being checked in multiple different for loops in the
hot path. The change to allow xdp_prog hot swapping created the
possibility for many READ_ONCE(q->xdp_prog) calls during a single napi
callback. Refactor the Rx napi handling to allow a previous
READ_ONCE(q->xdp_prog) (or NULL for hwstamp_rxq) to be passed into the
relevant functions.
Also, move other Rx related hotpath handling into the newly created
ionic_rx_cq_service() function to reduce the scope of the xdp_prog
local variable and put all Rx handling in one function similar to Tx.

Our home-grown buffer management needs to go away and we need
to be playing nicely with the page_pool infrastructure. This
converts the Rx traffic queues to use page_pool.
Also, since ionic_rx_buf_size() was removed, redefine
IONIC_PAGE_SIZE to account for IONIC_MAX_BUF_LEN being the
largest allowed buffer to prevent overflowing u16 variables,
which could happen when PAGE_SIZE is defined as >= 64KB.

Currently when going to/from a NULL XDP program the driver uses
ionic_stop_queues_reconfig() and then ionic_start_queues_reconfig() in
order to re-register the xdp_rxq_info and re-init the queues. This is
fine until page_pool(s) are used in an upcoming patch.
In preparation for adding page_pool support make sure to completely
rebuild the queues when going to/from a NULL XDP program. Without this
change the call to mem_allocator_disconnect() never happens when going
to a NULL XDP program, which eventually results in
xdp_rxq_info_reg_mem_model() failing with -ENOSPC due to the mem_id_pool
ida having no remaining space.

Instead of setting up and tearing down the rxq_info only when the XDP
program is loaded or unloaded, we will build the rxq_info whether or not
XDP is in use. This is the more common use pattern and better supports
future conversion to page_pool. Since the rxq_info wants the napi_id
we re-order things slightly to tie this into the queue init and deinit
functions where we do the add and delete of napi.

We originally were using a per-interface xdp_prog variable to track
a loaded XDP program since we knew there would never be support for a
per-queue XDP program. With that, we only built the per queue rxq_info
struct when an XDP program was loaded and removed it on XDP program unload,
and used the pointer as an indicator in the Rx hotpath to know to how build
the buffers. However, that's really not the model generally used, and
makes a conversion to page_pool Rx buffer cacheing a little problematic.
This patch converts the driver to use the more common approach of using
a per-queue xdp_prog pointer to work out buffer allocations and need
for bpf_prog_run_xdp(). We jostle a couple of fields in the queue struct
in order to keep the new xdp_prog pointer in a warm cacheline.

We aren't "putting" buf, we're just unlinking them from our tracking in
order to let the XDP_TX and XDP_REDIRECT tx clean paths take care of the
pages when they are done with them. This rename clears up the intent.

Here's a little debugging aid in case the device starts throwing

The responsibility for reporting of RX software timestamp has moved to
the core layer (see __ethtool_get_ts_info()), remove usage from the
device drivers.
