Buffer 'card->dai_link' is reallocated in 'meson_card_reallocate_links()',
so move 'pad' pointer initialization after this function when memory is
already reallocated.

At least if rsnd is using DPCM connection on Audio-Graph-Card2,
fw_devlink might doesn't have enough information to break the cycle
(Same problem might occur with Multi-CPU/Codec or Codec2Codec).
In such case, rsnd driver will not be probed.
Add post-init-providers support to break the link cycle.

Merge series from Jens Reidel <adrian@travitia.xyz>:
This patch adds support for the primary mi2s interface on devices using SM8250
audio drivers. Tested on SM7150 (xiaomi-davinci). SM7150 sound is close to
SM8250 and we intend to use it as a fallback in the future.

[Why]
DC has a special commit path for native cursor, which use the built-in
cursor pipe within DCN planes. This update path does not require all
enabled planes to be added to the list of surface updates sent to DC.
This is not the case for overlay cursor; it uses the same path as MPO
commits. This update path requires all enabled planes to be added to the
list of surface updates sent to DC. Otherwise, DC will disable planes
not inside the list.
[How]
If overlay cursor is needed, add all planes on the same CRTC as this
cursor to the atomic state. This is already done for non-cursor planes
(MPO), just before the added lines.
Fixes: 1b04dcca4fb1 ("drm/amd/display: Introduce overlay cursor mode")

The behavior of regulator_dev_lookup() for non-DT way has been broken
since the commit b8c325545714 ("regulator: Move OF-specific regulator
lookup code to of_regulator.c").
Before the commit, of_get_regulator() was used to get the regulator,
which returns NULL if the regulator is not found. So the regulator
will be looked up through regulator_lookup_by_name() if no matching
regulator is found in regulator_map_list.
However, currently, of_regulator_dev_lookup() is used to instead of
of_get_regulator(), but the variable 'r' is set to ERR_PTR(-ENODEV)
instead of NULL if the regulator is not found. In this case, if no
regulator is found in regulator_map_list, the variable 'r' is still
ERR_PTR(-ENODEV), So regulator_dev_lookup() returns the value of 'r'
directly instead of continuing to look up the regulator through
regulator_lookup_by_name().

Improve the DMA descriptor calculation by dividing the period size by the
product of sample size and DMA chunk size, rather than just DMA chunk size.
Ensure that all DMA descriptors start from a well-aligned address to
improve the reliability and efficiency of DMA operations and avoid
potential issues related to misaligned descriptors.
[andrei.simion@microchip.com: Adjust the commit title. Reword the commit
message. Add MACROS for each DMA size chunk supported by mchp-pdmc.
Add DMA_BURST_ALIGNED preprocesor function to check the alignment of the

cpumap takes RX processing out of softirq and onto a separate kthread.
Since the kthread needs to be scheduled in order to run (versus softirq
which does not), we can theoretically experience extra latency if the
system is under load and the scheduler is being unfair to us.
Moving the tracepoint to before passing the skb list up the stack allows
users to more accurately measure enqueue/dequeue latency introduced by
cpumap via xdp:xdp_cpumap_enqueue and xdp:xdp_cpumap_kthread tracepoints.
f9419f7bd7a5 ("bpf: cpumap add tracepoints") which added the tracepoints
states that the intent behind them was for general observability and for
a feedback loop to see if the queues are being overwhelmed. This change
does not mess with either of those use cases but rather adds a third
one.

Rather than passing a fake PMU around, just pass that the fake PMU
should be used - true when doing testing. Move the fake PMU into
pmus.[ch] and try to abstract the PMU's properties in pmu.c, ie so
there is less "if fake_pmu" in non-PMU code. Give the fake PMU a made
up type number.

It turned out that the topology ABI takes the standard PCM rate bits
as is, and it means that the recent change of the PCM rate bits would
lead to the inconsistent rate values used for topology.
This patch reverts the original PCM rate bit definitions while adding
the new rates to the extended bits instead. This needed the change of
snd_pcm_known_rates, too. And this also required to fix the handling
in snd_pcm_hw_limit_rates() that blindly assumed that the list is
sorted while it became unsorted now.

Add a bigger size from folio to bio and skip merge processing for pages.
Fetch the offset of page within a folio. Depending on the size of folio
and folio_offset, fetch a larger length. This length may consist of
multiple contiguous pages if folio is multiorder.
Using the length calculate number of pages which will be added to bio and
increment the loop counter to skip those pages.
This technique helps to avoid overhead of merging pages which belong to
same large order folio.
Also folio-ize the functions bio_iov_add_page() and
bio_iov_add_zone_append_page()

_from_ userspace
We need to decide where to copy syscall arg contents, if at the
syscalls:sys_entry hook, meaning is something that is coming from
user to kernel space, or if it is a response, i.e. if it is something
the _kernel_ is filling in and thus going to userspace.
Since we have 'const' used in those syscalls, and unsure about this
being consistent, doing:
root@number:~# echo $(grep const /sys/kernel/tracing/events/syscalls/sys_enter_*/format | grep struct | cut -c47- | cut -d'/' -f1)
clock_nanosleep clock_settime epoll_pwait2 futex io_pgetevents landlock_create_ruleset listmount mq_getsetattr mq_notify mq_timedreceive mq_timedsend preadv2 preadv prlimit64 process_madvise process_vm_readv process_vm_readv process_vm_writev process_vm_writev pwritev2 pwritev readv rt_sigaction rt_sigtimedwait semtimedop statmount timerfd_settime timer_settime vmsplice writev
root@number:~#
Seems to indicate that we can use that for the ones that have the
'const' to mark it as coming from user space, do it.
Most notable/frequent syscall that now gets BTF pretty printed in a
system wide 'perf trace' session is:

On some newer laptops ASUS laptops SPS support is advertised but not
actually used, causing the AMD driver to register as a platform_profile
handler.
If this happens then the asus_wmi driver would error with -EEXIST when
trying to register its own handler leaving the user with a possibly
unusable system. This is especially true for laptops with an MCU that emit
a stream of HID packets, some of which can be misinterpreted as shutdown
signals.
We can safely continue loading the driver instead of bombing out.

Add support to ignore all LTRs before suspend and restore the previous
LTR values after suspend. This feature could be turned off with module
parameter ltr_ignore_all_suspend.
LTR value is a mechanism for a device to indicate tolerance to access
the corresponding resource. When system suspends, the resource is not
available and therefore the LTR value could be ignored. Ignoring all
LTR values prevents problematic device from blocking the system to get
to the deepest package state during suspend.

The memory scheme page fault event is a new approch in handling page fault
on mkeys using the on-demand-paging feature.
The major shift in handling the page fault in this scheme is that the HW
is taking responsibilty for parsing the faulted mkey instead of the
previous approach where the driver would read and parse the wqes and
query the mkeys to get to the direct mkey that we need to handle.
Therefore, the event we get from FW in this scheme will contain the
direct mkey and address we need to handle and require much less work
from driver.
Additionally, to optimize performance, the FW can generate the event on
a memory area that is larger than the faulted memory operation is
requiring, to 'prefetch' memory that is around it and will likely be
used soon.
Unlike previous types of page fault, the memory page scheme fault does
not always require a resume command after handling the page fault as the FW
can post multiple events on same mkey and will set the 'last' flag only on
the page fault that requires the resume command.

The new memory scheme page faults are requesting the driver to fetch
additinal pages to the faulted memory access.
This is done in order to prefetch pages before and after the area that
got the page fault, assuming this will reduce the total amount of page
faults.
The driver should ensure it handles only the pages that are within the
umem range.
