Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
support for NVL-S and the support using functional topology fragments for
Soundwire configurations is introduced in 6.19-rc1 in parallel.
The SOF projects plan is to not create individual topology files for NVL
as with SDCA and the functional topology support can handle most if not
all soundwire devices going forward.
However one issue have been identified with the functional topology only
support, which was masked by the presence of a single topology file:
if the device contains a dai link for which we don't have topology fragment,
then the probe will fail.
This worked with a fallback to a monolithic topology file - which made the
dai link to be ignored.
The first patch in the series adds a flag to instruct the function discovery
to make a best effort to form a card by ignoring functions without
corresponding fragment (and print this out for developers) in case there
is no fallback topology available.
The second patch removes the match entry to refer to a topology file which
will not be built by the SOF project.
Pass character "0" rather than NULL terminator to properly format
queue restoration SMI events. Currently, the NULL terminator precedes
the newline character that is intended to delineate separate events
in the SMI event buffer, which can break userspace parsers.

User-configured SCLK(GPU core clock)frequencies were not persisting
across S0ix suspend/resume cycles on smu v14 hardware.
The issue occurred because of the code resetting clock frequency
to zero during resume.
This patch addresses the problem by:
- Preserving user-configured values in driver and sets the
clock frequency across resume
- Preserved settings are sent to the hardware during resume

Commit 8a6e02d0c0 ("of: reserved_mem: Restructure how the reserved
memory regions are processed") changed the processing order of reserved
memory regions, causing elfcorehdr to overlap with dynamically allocated
reserved memory regions during kdump kernel boot.
The issue occurs because:
1. kexec-tools allocates elfcorehdr in the last crashkernel reserved
memory region and passes it to the second kernel
2. The problematic commit moved dynamic reserved memory allocation
(like bman-fbpr) to occur during fdt_scan_reserved_mem(), before
elfcorehdr reservation in fdt_reserve_elfcorehdr()
3. bman-fbpr with 16MB alignment requirement can get allocated at
addresses that overlap with the elfcorehdr location
4. When fdt_reserve_elfcorehdr() tries to reserve elfcorehdr memory,
overlap detection identifies the conflict and skips reservation
5. kdump kernel fails with "Unable to handle kernel paging request"
because elfcorehdr memory is not properly reserved
The boot log:
Before 8a6e02d0c0:
OF: fdt: Reserving 1 KiB of memory at 0xf4fff000 for elfcorehdr
OF: reserved mem: 0xf3000000..0xf3ffffff bman-fbpr
After 8a6e02d0c0:
OF: reserved mem: 0xf4000000..0xf4ffffff bman-fbpr
OF: fdt: elfcorehdr is overlapped
Fix this by ensuring elfcorehdr reservation occurs before dynamic
reserved memory allocation.

Add dma_set_mask(), dma_set_coherent_mask(), dma_map_sgtable(), and
dma_max_mapping_size() helpers to fix a build error when
CONFIG_HAS_DMA is not enabled.
Note that when CONFIG_HAS_DMA is enabled, they are included in both
bindings_generated.rs and bindings_helpers_generated.rs. The former
takes precedence so behavior remains unchanged in that case.

The new XFS_ERRTAG_FORCE_ZERO_RANGE error tag added by commit
ea9989668081 ("xfs: error tag to force zeroing on debug kernels") fails
to account for the zoned space reservation rules and this reliably fails
xfs/131 because the zeroing operation returns -EIO.
Fix this by reserving enough space to zero the entire range, which
requires a bit of (fairly ugly) reshuffling to do the error injection
early enough to affect the space reservation.

maple_tree insertions can fail if we are seriously short on memory;
simple_offset_rename() does not recover well if it runs into that.
The same goes for simple_offset_rename_exchange().
Moreover, shmem_whiteout() expects that if it succeeds, the caller will
progress to d_move(), i.e. that shmem_rename2() won't fail past the
successful call of shmem_whiteout().
Not hard to fix, fortunately - mtree_store() can't fail if the index we
are trying to store into is already present in the tree as a singleton.
For simple_offset_rename_exchange() that's enough - we just need to be
careful about the order of operations.
For simple_offset_rename() solution is to preinsert the target into the
tree for new_dir; the rest can be done without any potentially failing
operations.
That preinsertion has to be done in shmem_rename2() rather than in
simple_offset_rename() itself - otherwise we'd need to deal with the
possibility of failure after successful shmem_whiteout().

As describe in the help string, the user might want to disable these
tests if they don't like to see stacktraces/BUG etc in their kernel log.
However, if they enable PANIC_ON_OOPS, these tests also crash the
machine, which it's safe to assume _almost_ nobody wants.
One might argue that _absolutely_ nobody ever wants their kernel to
crash so this should just be a hard dependency instead of a default.
However, since this is rather special code that's anyway concerned with
deliberately doing "bad" things, the normal rules don't seem to apply,
hence prefer flexibility and allow users to set up a crashing Kconfig if
they so choose.

When there is no fallback possibility available for the function topology
use it is better to try to create a profile for the card in best effort
manner, leaving out non supported links for example.
As an example: some laptops present SSPx-BT link but we don't have fragment
yet to support this. If we only have support for functional topology
without monolithic fallback then we would fail the card creation.
The reason why the monolithic topology works on the same device is that it
does not have the SSPx-BT link handled, it is ignored.
In case when there is no fallback possibility we should try to create the
card with links that we support as best effort instead of failing and
leaving the user without a card.
