Expose a sysfs identifier encapsulating the CMN part number and revision
so that jevents can narrow down a fundamental set of possible events for
calculating metrics. Configuration-dependent aspects - such as whether a
given node type is present, and/or a given node ID is valid - are still
not covered, and in general it's hard to see how userspace could handle
them, so we won't be removing any data or validation logic from the
driver any time soon, but at least it's a step in a useful direction.

CMN implements a set of CoreSight-format peripheral ID registers which
in principle we should be able to use to identify the hardware. However
so far we have avoided trying to use the part number field since the
TRMs have all described it as "configuration dependent". It turns out,
though, that this is a quirk of the documentation generation process,
and in fact the part number should always be a stable well-defined field
which we can trust.
To that end, revamp our model detection to rely less on ACPI/DT, and
pave the way towards further using the hardware information as an
identifier for userspace jevent metrics. This includes renaming the
revision constants to maximise readability.

With offloading enabled, esp_xmit() gets invoked very late, from within
validate_xmit_xfrm() which is after validate_xmit_skb() validates and
linearizes the skb if the underlying device does not support fragments.
esp_output_tail() may add a fragment to the skb while adding the auth
tag/ IV. Devices without the proper support will then send skb->data
points to with the correct length so the packet will have garbage at the
end. A pcap sniffer will claim that the proper data has been sent since
it parses the skb properly.
It is not affected with INET_ESP_OFFLOAD disabled.
Linearize the skb after offloading if the sending hardware requires it.
It was tested on v4, v6 has been adopted.

Initializing the FPU during the early boot process is a pointless
exercise. Early boot is convoluted and fragile enough.
Nothing requires that the FPU is set up early. It has to be initialized
before fork_init() because the task_struct size depends on the FPU register
buffer size.
Move the initialization to arch_cpu_finalize_init() which is the perfect
place to do so.
No functional change.
This allows to remove quite some of the custom early command line parsing,
but that's subject to the next installment.

X86 is reworking the boot process so that initializations which are not
required during early boot can be moved into the late boot process and out
of the fragile and restricted initial boot phase.
arch_cpu_finalize_init() is the obvious place to do such initializations,
but arch_cpu_finalize_init() is invoked too late in start_kernel() e.g. for
initializing the FPU completely. fork_init() requires that the FPU is
initialized as the size of task_struct on X86 depends on the size of the
required FPU register buffer.
Fortunately none of the init calls between calibrate_delay() and
arch_cpu_finalize_init() is relevant for the functionality of
arch_cpu_finalize_init().
Invoke it right after calibrate_delay() where everything which is relevant
for arch_cpu_finalize_init() has been set up already.
No functional change intended.

check_bugs() has become a dumping ground for all sorts of activities to
finalize the CPU initialization before running the rest of the init code.
Most are empty, a few do actual bug checks, some do alternative patching
and some cobble a CPU advertisement string together....
Aside of that the current implementation requires duplicated function
declaration and mostly empty header files for them.
Provide a new function arch_cpu_finalize_init(). Provide a generic
declaration if CONFIG_ARCH_HAS_CPU_FINALIZE_INIT is selected and a stub
inline otherwise.
This requires a temporary #ifdef in start_kernel() which will be removed
along with check_bugs() once the architectures are converted over.

This commit adds new DEVICE_FLG with QUIRK_FLAG_DSD_RAW and Vendor Id for
HEM devices which supports native DSD. Prior to this change Linux kernel
was not enabling native DSD playback for HEM devices, and as a result,
DSD audio was being converted to PCM "on the fly". HEM devices,
when connected to the system, would only play audio in PCM format,
even if the source material was in DSD format. With the addition of new
VENDOR_FLG in the quircks.c file, the devices are now correctly
recognized, and raw DSD data is transmitted to the device,
allowing for native DSD playback.

As reported in the bugzilla below, the PM resume of a UAC3 device may
fail due to the incomplete power state change, stuck at D1. The
reason is that the driver expects the full D0 power state change only
at hw_params, while the normal PCM resume procedure doesn't call
hw_params.
For fixing the bug, we add the same power state update to D0 at the
prepare callback, which is certainly called by the resume procedure.
Note that, with this change, the power state change in the hw_params
becomes almost redundant, since snd_usb_hw_params() doesn't touch the
parameters (at least it tires so). But dropping it is still a bit
risky (e.g. we have the media-driver binding), so I leave the D0 power
state change in snd_usb_hw_params() as is for now.

Although snd_seq_oss_midi_open() and snd_seq_oss_midi_close() can be
called concurrently from different code paths, we have no proper data
protection against races. Introduce open_mutex to each seq_oss_midi
object for avoiding the races.

====================
Check if FIPS mode is enabled when running selftests
Some test cases from net/tls, net/fcnal-test and net/vrf-xfrm-tests
that rely on cryptographic functions to work and use non-compliant FIPS
algorithms fail in FIPS mode.
In order to allow these tests to pass in a wider set of kernels,
- for net/tls, skip the test variants that use the ChaCha20-Poly1305
and SM4 algorithms, when FIPS mode is enabled;
- for net/fcnal-test, skip the MD5 tests, when FIPS mode is enabled;
- for net/vrf-xfrm-tests, replace the algorithms that are not
FIPS-compliant with compliant ones.

The vrf-xfrm-tests tests use the hmac(md5) and cbc(des3_ede)
algorithms for performing authentication and encryption, respectively.
This causes the tests to fail when fips=1 is set, since these algorithms
are not allowed in FIPS mode. Therefore, switch from hmac(md5) and
cbc(des3_ede) to hmac(sha1) and cbc(aes), which are FIPS compliant.

Before executing each test from a fixture, FIXTURE_SETUP is run once.
When SKIP is used in FIXTURE_SETUP, the setup function returns early
but the test still proceeds to run, unless another SKIP macro is used
within the test definition, leading to some code repetition. Therefore,
allow tests to be skipped directly from the setup function.

Pull regmap fix from Mark Brown:
"Another fix for the maple tree cache, Takashi noticed that unlike
other caches the maple tree cache didn't check for read only registers
before trying to sync which would result in spurious syncs for read
only registers where we don't have a default.
This was due to the check being open coded in the caches, we now check
in the shared 'does this register need sync' function so that is fixed
for this and future caches"

This seems to have existed for ever but is now more apparant after
commit 9bff18d13473 ("drm/ttm: use per BO cleanup workers")
My analysis: two threads are running, one in the irq signalling the
fence, in dma_fence_signal_timestamp_locked, it has done the
DMA_FENCE_FLAG_SIGNALLED_BIT setting, but hasn't yet reached the
callbacks.
The second thread in nouveau_cli_work_ready, where it sees the fence is
signalled, so then puts the fence, cleanups the object and frees the
work item, which contains the callback.
Thread one goes again and tries to call the callback and causes the
use-after-free.
Proposed fix: lock the fence signalled check in nouveau_cli_work_ready,
so either the callbacks are done or the memory is freed.

====================
udplite/dccp: Print deprecation notice.
UDP-Lite is assumed to have no users for 7 years, and DCCP is
orphaned for 7 years too.
Let's add deprecation notice and see if anyone responds to it.

DCCP was marked as Orphan in the MAINTAINERS entry 2 years ago in commit
054c4610bd05 ("MAINTAINERS: dccp: move Gerrit Renker to CREDITS"). It says
we haven't heard from the maintainer for five years, so DCCP is not well
maintained for 7 years now.
Recently DCCP only receives updates for bugs, and major distros disable it
by default.
Removing DCCP would allow for better organisation of TCP fields to reduce
the number of cache lines hit in the fast path.
Let's add a deprecation notice when DCCP socket is created and schedule its
removal to 2025.

Recently syzkaller reported a 7-year-old null-ptr-deref [0] that occurs
when a UDP-Lite socket tries to allocate a buffer under memory pressure.
Someone should have stumbled on the bug much earlier if UDP-Lite had been
used in a real app. Also, we do not always need a large UDP-Lite workload
to hit the bug since UDP and UDP-Lite share the same memory accounting
limit.
Removing UDP-Lite would simplify UDP code removing a bunch of conditionals
in fast path.
Let's add a deprecation notice when UDP-Lite socket is created and schedule
its removal to 2025.
