Old code like amateur radio and NFC have long been a burden
to core networking developers. syzbot loves to find bugs
in BKL-era code, and noobs try to fix them.
If we want to have a fighting chance of surviving the LLM-pocalypse
this code needs to find a dedicated owner or get deleted.
We've talked about these deletions multiple times in the past
and every time someone wanted the code to stay. It is never
very clear to me how many of those people actually use the code
vs are just nostalgic to see it go. Amateur radio did have
occasional users (or so I think) but most users switched
to user space implementations since its all super slow stuff.
Nobody stepped up to maintain the kernel code.
We were lucky enough to find someone who wants to help with NFC
so we're giving that a chance. Let's try to put the rest of
this code behind us.

Remove CAIF (Communication CPU to Application CPU Interface), the
ST-Ericsson modem protocol. The subsystem has been orphaned since 2013.
The last meaningful changes from the maintainers were in March 2013:
a8c7687bf2 ("caif_virtio: Check that vringh_config is not null")
b2273be8d2 ("caif_virtio: Use vringh_notify_enable correctly")
0d2e1a2926 ("caif_virtio: Introduce caif over virtio")
Not-so-coincidentally, according to "the Internet" ST-Ericsson officially
shut down its modem joint venture in Aug 2013.
If anyone is using this code please yell!
In the 13 years since, the code has accumulated 200 non-merge commits,
of which 71 were cross-tree API changes, 21 carried Fixes: tags, and
the remaining ~110 were cleanups, doc conversions, treewide refactors,
and one partial removal (caif_hsi, ca75bcf0a8).
We are still getting fixes to this code, in the last 10 days there were
3 reports on security@ about CAIF that I have been CCed on.
UAPI constants (AF_CAIF, ARPHRD_CAIF, N_CAIF, VIRTIO_ID_CAIF) and the
SELinux classmap entry are intentionally kept for ABI stability.

is for OMAP2/3, which were not that well supported in the generic arm32

Remove the "michael_mic" crypto_shash algorithm, since it's no longer
used. Its only users were wireless drivers, which have now been
converted to use the michael_mic() function instead.
It makes sense that no other users ever appeared: Michael MIC is an
insecure algorithm that is specific to WPA TKIP, which itself was an
interim security solution to replace the broken WEP standard.

Since multi_v7_defconfig is meant to be the generic defconfig, many
users are not going to be experts and it is counterintuitive to have
CONFIG_EXPERT enabled.
This change has a couple of side-effects:
- CONFIG_NAMESPACES is enabled by default. This adds about 0.2% of
.text, but is already enabled in many board specific configs, and
apparently a requirement for systemd, so this seems like a useful
change.
- CONFIG_DEBUG_MEMORY_INIT is enabled now, adding a tiny bit
of code in the inittext section
- CONFIG_RFKILL, CONFIG_MEDIA_SUPPORT_FILTER and various CONFIG_HID
driver defaults change, so these have to be listed explicitly to
maintain the previous behavior
- CONFIG_SERIAL_SH_SCI_NR_UARTS=20 changes to the default value
of 18, which I understand to be sufficient for any buard, even
if all UARTS are enabled at the same time

The softlockup_panic sysctl is currently a binary option: panic
immediately or never panic on soft lockups.
Panicking on any soft lockup, regardless of duration, can be overly
aggressive for brief stalls that may be caused by legitimate operations.
Conversely, never panicking may allow severe system hangs to persist
undetected.
Extend softlockup_panic to accept an integer threshold, allowing the
kernel to panic only when the normalized lockup duration exceeds N
watchdog threshold periods. This provides finer-grained control to
distinguish between transient delays and persistent system failures.
The accepted values are:
- 0: Don't panic (unchanged)
- 1: Panic when duration >= 1 * threshold (20s default, original behavior)
- N > 1: Panic when duration >= N * threshold (e.g., 2 = 40s, 3 = 60s.)
The original behavior is preserved for values 0 and 1, maintaining full
backward compatibility while allowing systems to tolerate brief lockups
while still catching severe, persistent hangs.

Move the ARM optimized single-block AES en/decryption code into
lib/crypto/, wire it up to the AES library API, and remove the
superseded "aes-arm" crypto_cipher algorithm.
The result is that both the AES library and crypto_cipher APIs are now
optimized for ARM, whereas previously only crypto_cipher was (and the
optimizations weren't enabled by default, which this fixes as well).

This option explicitly selects other options, e.g. SND_SOC_FSL_SAI.
These SAI drivers use DMA which in turn is dependent on CONFIG_IMX_SDMA.
SDMA needs a firmware which is not yet present if the driver is built-in.
Thus build CONFIG_SND_SOC_FSL_ASOC_CARD to avoid useless driver probe
deferrals due to missing DMA channels.

the enablement of CIX HD-audio controller, which took a bit time to
be cooked up, while most of other changes are device-specific small
trivial fixes.
- Default disablement of the kconfig for decades old pre-release
alsa-lib PCM API; it's only the default config value change, so
it can't lead to any regressions for the existing setups
- Support for CIX HD-audio controller
- A few ASoC ACP fixes

Here is the big set of tty/serial driver changes for 6.19-rc1. Nothing
major at all, just small constant churn to make the tty layer "cleaner"
as well as serial driver updates and even a new test added! Included in
here are:
- More tty/serial cleanups from Jiri
- tty tiocsti test added to hopefully ensure we don't regress in this
area again
- sc16is7xx driver updates
- imx serial driver updates
- 8250 driver updates
- new hardware device ids added
- other minor serial/tty driver cleanups and tweaks
All of these have been in linux-next for a while with no reported issues
other than a merge-conflict that you will have when you merge into your
tree (should be simple to resolve, just delete the code on both sides
of the merge).

- The 6 patch series "panic: sys_info: Refactor and fix a potential
issue" from Andy Shevchenko fixes a build issue and does some cleanup in
ib/sys_info.c.
- The 9 patch series "Implement mul_u64_u64_div_u64_roundup()" from
David Laight enhances the 64-bit math code on behalf of a PWM driver and
beefs up the test module for these library functions.
- The 2 patch series "scripts/gdb/symbols: make BPF debug info available
to GDB" from Ilya Leoshkevich makes BPF symbol names, sizes, and line
numbers available to the GDB debugger.
- The 4 patch series "Enable hung_task and lockup cases to dump system
info on demand" from Feng Tang adds a sysctl which can be used to cause
additional info dumping when the hung-task and lockup detectors fire.
- The 6 patch series "lib/base64: add generic encoder/decoder, migrate
users" from Kuan-Wei Chiu adds a general base64 encoder/decoder to lib/
and migrates several users away from their private implementations.
- The 2 patch series "rbree: inline rb_first() and rb_last()" from Eric

Live Update Orchestrator (LUO), and possibly for other future clients.
- The 13 patch series "kho: simplify state machine and enable dynamic
updates" from Pasha Tatashin increases the flexibility of KEXEC
Handover. Also preparation for LUO.
- The 18 patch series "Live Update Orchestrator" from Pasha Tatashin is
a major new feature targeted at cloud environments. Quoting the [0/N]:
This series introduces the Live Update Orchestrator, a kernel subsystem
designed to facilitate live kernel updates using a kexec-based reboot.
This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file
descriptors, which allows critical in-memory data, such as guest RAM or
any other large memory region, to be maintained in RAM across the kexec
reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- The 3 patch series "kexec: reorganize kexec and kdump sysfs" from
Sourabh Jain moves the kexec and kdump sysfs entries from /sys/kernel/
to /sys/kernel/kexec/ and adds back-compatibility symlinks which can
hopefully be removed one day.
- The 2 patch series "kho: fixes for vmalloc restoration" from Mike
Rapoport fixes a BUG which was being hit during KHO restoration of
vmalloc() regions.

Remove ansi_cprng, since it's obsolete and unused, as confirmed at
https://lore.kernel.org/r/aQxpnckYMgAAOLpZ@gondor.apana.org.au/
This was originally added in 2008, apparently as a FIPS approved random
number generator. Whether this has ever belonged upstream is
questionable. Either way, ansi_cprng is no longer usable for this
purpose, since it's been superseded by the more modern algorithms in
crypto/drbg.c, and FIPS itself no longer allows it. (NIST SP 800-131A
Rev 1 (2015) says that RNGs based on ANSI X9.31 will be disallowed after
2015. NIST SP 800-131A Rev 2 (2019) confirms they are now disallowed.)
Therefore, there is no reason to keep it around.

In 3.7, 8250 was unintentionally renamed to 8250_core. This happened in
the commit 835d844d1a (8250_pnp: do pnp probe before legacy probe).
This made 8250.<xxxx> module options effectively defunct. Instead,
8250_core.<xxxx> worked.
In 3.9, the commit f2b8dfd9e4 (serial: 8250: Keep 8250.<xxxx> module
options functional after driver rename) made the original options work
again by introducing a hack.
Later in 3.9, the commit 9196d8acd7 (TTY: 8250, revert module name
change) changed the module name back to 8250 (from 8250_core). Since
then, the hack was there to support the transient 8250_core.<xxxx>
options. Those were present only in the 3.7..3.9 range.
These transient options were deprecated by 9326b047e4 (TTY: 8250,
deprecated 8250_core.* options) in v3.9 too.
Now, after those 12 years, it is time to get rid of this hack
completely.

The Programmable Real-time Unit and Industrial Communication Subsystem
Megabit (ICSSM) is a microcontroller subsystem in TI SoCs such as
AM57x, AM437x, and AM335x. It provides real-time processing
capabilities for industrial communication and custom peripheral interfaces.
Currently, EVMs based on AM57x, AM437x, and AM335x use the ICSSM driver
for PRU-based Ethernet functionality.
This patch enables TI_PRUSS and TI_PRUETH as a module for TI SoCs.
