When the kernel is built without UMP support but a user-space app
requires the midi_version > 0, the kernel should return an error.
Otherwise user-space assumes as if it were possible to deal,
eventually hitting serious errors later.

Similar to commit eb91c456f371
("ALSA: hda/realtek: Add Framework Laptop 13 (Intel Core Ultra) to quirks")
and previous quirks for Framework systems with
Realtek codecs.
000C is a new platform that will also have an ALC285 codec and needs the
same quirk.

This reverts commit c2d188e137e77294323132a760a4608321a36a70.
Although it's fine to filter the invalid UMP groups at the first probe
time, this will become a problem when UMP groups are updated and
(re-)activated. Then there is no way to re-add the substreams
properly for the legacy rawmidi, and the new active groups will be
still invisible.
So let's revert the change. This will move back to showing the full
16 groups, but it's better than forever lost.

OSS sequencer handles the SysEx messages split in 6 bytes packets, and
ALSA sequencer OSS layer tries to combine those. It stores the data
in the internal buffer and this access is racy as of now, which may
lead to the out-of-bounds access.
As a temporary band-aid fix, introduce a mutex for serializing the
process of the SysEx message packets.

3d3f43fab4cf ("ALSA: compress_offload: improve file descriptors
installation for dma-buf") fixed some of descriptor races in
snd_compr_task_new(), but there's a couple more left.
We need to grab the references to dmabuf before moving them into
descriptor table - trying to do that by descriptor afterwards might
end up getting a different object, with a dangling reference left in
task->{input,output}

The pattern rule `$(OUTPUT)/%: %.c` inadvertently included a circular
dependency on the global-timer target due to its inclusion in
$(TEST_GEN_PROGS_EXTENDED). This resulted in a circular dependency
warning during the build process.
To resolve this, the dependency on $(TEST_GEN_PROGS_EXTENDED) has been
replaced with an explicit dependency on $(OUTPUT)/libatest.so. This change
ensures that libatest.so is built before any other targets that require it,
without creating a circular dependency.
This fix addresses the following warning:
make[4]: Entering directory 'tools/testing/selftests/alsa'
make[4]: Circular default_modconfig/kselftest/alsa/global-timer <- default_modconfig/kselftest/alsa/global-timer dependency dropped.

On Chromebooks based on Mediatek MT8195 or MT8188, the audio frontend
(AFE) is limited to accessing a very small window (1 MiB) of memory,
which is described as a reserved memory region in the device tree.
On these two platforms, the maximum buffer size is given as 512 KiB.
The MediaTek common code uses the same value for preallocations. This
means that only the first two PCM substreams get preallocations, and
then the whole space is exhausted, barring any other substreams from
working. Since the substreams used are not always the first two, this
means audio won't work correctly.
This is observed on the MT8188 Geralt Chromebooks, on which the
"mediatek,dai-link" property was dropped when it was upstreamed. That
property causes the driver to only register the PCM substreams listed
in the property, and in the order given.
Instead of trying to compute an optimal value and figuring out which
streams are used, simply disable preallocation. The PCM buffers are
managed by the core and are allocated and released on the fly. There
should be no impact to any of the other MediaTek platforms.

The linkDMA should not be released on stop trigger since a stream re-start
might happen without closing of the stream. This leaves a short time for
other streams to 'steal' the linkDMA since it has been released.
This issue is not easy to reproduce under normal conditions as usually
after stop the stream is closed, or the same stream is restarted, but if
another stream got in between the stop and start, like this:
aplay -Dhw:0,3 -c2 -r48000 -fS32_LE /dev/zero -d 120
CTRL+z
aplay -Dhw:0,0 -c2 -r48000 -fS32_LE /dev/zero -d 120
then the link DMA channels will be mixed up, resulting firmware error or
crash.

BPF program types like kprobe and fentry can cause deadlocks in certain
situations. If a function takes a lock and one of these bpf programs is
hooked to some point in the function's critical section, and if the
bpf program tries to call the same function and take the same lock it will
lead to deadlock. These situations have been reported in the following
bug reports.

Prevent kprobe and fentry bpf programs from attaching to these critical
sections by removing CC_FLAGS_FTRACE for percpu_freelist.o,
bpf_lru_list.o, queue_stack_maps.o, lpm_trie.o, ringbuf.o files.
The bugs reported by syzbot are due to tracepoint bpf programs being
called in the critical sections. This patch does not aim to fix deadlocks
caused by tracepoint programs. However, it does prevent deadlocks from
occurring in similar situations due to kprobe and fentry programs.
