drm_color_ctm_3x4 is some undocumented amgdpu private
uapi and thus has no business being in drm_mode.h.
At least move it to some amdgpu specific header, albeit
with the wrong namespace as maybe something somewhere
is using this already?

Cleanup some deprecated uses of strncpy() and strcpy() [1].
There doesn't seem to be any bugs with the current code but the
readability of this code could benefit from a quick makeover while
removing some deprecated stuff as a benefit.
The most interesting replacement made in this patch involves
concatenating "ttyS" with a digit-led user-supplied string. Instead of
doing two distinct string copies with carefully managed offsets and
lengths, let's use the more robust and self-explanatory scnprintf().
scnprintf will 1) respect the bounds of @buf, 2) null-terminate @buf, 3)
do the concatenation. This allows us to drop the manual NUL-byte assignment.
Also, since isdigit() is used about a dozen lines after the open-coded
version we'll replace it for uniformity's sake.
All the strcpy() --> strscpy() replacements are trivial as the source
strings are literals and much smaller than the destination size. No
behavioral change here.
Use the new 2-argument version of strscpy() introduced in Commit
e6584c3964f2f ("string: Allow 2-argument strscpy()"). However, to make
this work fully (since the size must be known at compile time), also
update the extern-qualified declaration to have the proper size
information.

Currently the documentation for line names allows to use %u inside
the alternative name. This is broken in character device approach
from day 1 and being in use solely in sysfs.
Character device interface has a line number as a part of its address,
so the users better rely on it. Hence remove the misleading documentation.
On top of that, there are no in-kernel users (out of 6, if I'm correct)
for such names and moreover if one exists it won't help in distinguishing
lines with the same naming as '%u' will also be in them and we will get
a warning in gpiochip_set_desc_names() for such cases.

On x86_64 and allmodconfig, this shrinks the size of 'struct regmap_config'
from 328 to 312 bytes.
This is usually a win, because this structure is used as a static global
variable.
When moving the kerneldoc fields, I've tried to keep the layout as
consistent as possible, which is not really easy!
Before:
/* size: 328, cachelines: 6, members: 55 */
/* sum members: 296, holes: 6, sum holes: 25 */
/* padding: 7 */
/* last cacheline: 8 bytes */
After:
/* size: 312, cachelines: 5, members: 55 */
/* sum members: 296, holes: 5, sum holes: 16 */
/* last cacheline: 56 bytes */
For the records, this is also widely used:
$git grep static.*regmap_config | wc -l

Add new iflink attributes to configure in-kernel UDP listener socket
address: IFLA_GTP_LOCAL and IFLA_GTP_LOCAL6. If none of these attributes
are specified, default is still to IPv4 INADDR_ANY for backward
compatibility.
Add new attributes to set up family and IPv6 address of GTP tunnels:
GTPA_FAMILY, GTPA_PEER_ADDR6 and GTPA_MS_ADDR6. If no GTPA_FAMILY is
specified, AF_INET is assumed for backward compatibility.
setsockopt IPV6_ADDRFORM allows to downgrade socket from IPv6 to IPv4
after socket is bound. Assumption is that socket listener that is
attached to the gtp device needs to be either IPv4 or IPv6. Therefore,
GTP socket listener does not allow for IPv4-mapped-IPv6 listener.

Currently GTP packets are dropped if the next extension field is set to
non-zero value, but this are valid GTP packets.
TS 29.281 provides a longer header format, which is defined as struct
gtp1_header_long. Such long header format is used if any of the S, PN, E
flags is set.
This long header is 4 bytes longer than struct gtp1_header, plus
variable length (optional) extension headers. The next extension header
field is zero is no extension header is provided.
The extension header is composed of a length field which includes total
number of 4 byte words including the extension header itself (1 byte),
payload (variable length) and next type (1 byte). The extension header
size and its payload is aligned to 4 bytes.
A GTP packet might come with a chain extensions headers, which makes it
slightly cumbersome to parse because the extension next header field
comes at the end of the extension header, and there is a need to check
if this field becomes zero to stop the extension header parser.

This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea.
Stephen Rostedt reports:
"I went to run my tests on my VMs and the tests hung on boot up.
Unfortunately, the most I ever got out was:
[ 93.607888] Testing event system initcall: OK
[ 93.667730] Running tests on all trace events:
[ 93.669757] Testing all events: OK
[ 95.631064] ------------[ cut here ]------------
Timed out after 60 seconds"
and further debugging points to a possible circular locking dependency
between the console_owner locking and the worker pool locking.
Reverting the commit allows Steve's VM to boot to completion again.
[ This may obviously result in the "[TTM] Buffer eviction failed"
messages again, which was the reason for that original revert. But at
this point this seems preferable to a non-booting system... ]

Previously, when a kernel test thread crashed (e.g. NULL pointer
dereference, general protection fault), the KUnit test hanged for 30
seconds and exited with a timeout error.
Fix this issue by waiting on task_struct->vfork_done instead of the
custom kunit_try_catch.try_completion, and track the execution state by
initially setting try_result with -EINTR and only setting it to 0 if
the test passed.
Fix kunit_generic_run_threadfn_adapter() signature by returning 0
instead of calling kthread_complete_and_exit(). Because thread's exit
code is never checked, always set it to 0 to make it clear. To make
this explicit, export kthread_exit() for KUnit tests built as module.
Fix the -EINTR error message, which couldn't be reached until now.
This is tested with a following patch.

The interface is a pair of getter/setter prctl's that work on a single
aspect at a time (multiple aspects at once is more difficult if there
are different rules applied for each aspect, now or in future). The
getter shows the current state of the process config, and the setter

All EV4 machines are already gone, and the remaining EV5 based machines
all support the slightly more modern EV56 generation as well.
Debian only supports EV56 and later.
Drop both of these and build kernels optimized for EV56 and higher
when the "generic" options is selected, tuning for an out-of-order
EV6 pipeline, same as Debian userspace.
Since this was the only supported architecture without 8-bit and
16-bit stores, common kernel code no longer has to worry about
aligning struct members, and existing workarounds from the block
and tty layers can be removed.
The alpha memory management code no longer needs an abstraction
for the differences between EV4 and EV5+.

So far Multicast Router Advertisements and Multicast Router
Solicitations from the Multicast Router Discovery protocol (RFC4286)
would be marked as INVALID for IPv6, even if they are in fact intact
and adhering to RFC4286.
This broke MRA reception and by that multicast reception on
IPv6 multicast routers in a Proxmox managed setup, where Proxmox
would install a rule like "-m conntrack --ctstate INVALID -j DROP"
at the top of the FORWARD chain with br-nf-call-ip6tables enabled
by default.
Similar to as it's done for MLDv1, MLDv2 and IPv6 Neighbor Discovery
already, fix this issue by excluding MRD from connection tracking
handling as MRD always uses predefined multicast destinations
for its messages, too. This changes the ct-state for ICMPv6 MRD messages
from INVALID to UNTRACKED.
This issue was found and fixed with the help of the mrdisc tool
(https://github.com/troglobit/mrdisc).

In IEEE 1394 bus, the type of asynchronous packet without any offset to
node address space is called as phy packet. The destination of packet is
IEEE 1394 phy itself. This type of packet is used for several purposes,
mainly for selfID at the state of bus reset, to force selection of root
node, and to adjust gap count.
This commit adds tracepoints events for the type of asynchronous outbound
packet. Like asynchronous outbound transaction packets, a pair of events
are added to trace initiation and completion of transmission.
In the case that the phy packet is sent by kernel API, the match between
the initiation and completion is not so easy, since the data of
'struct fw_packet' is allocated statically. In the case that it is sent by
userspace applications via cdev, the match is easy, since the data is
allocated per each.
This example is for Remote Access Packet by lsfirewirephy command in
linux-firewire-utils:

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

Merge series from David Lechner <[email protected]>:
In the IIO subsystem, we noticed a pattern in many drivers where we need
to get, enable and get the voltage of a supply that provides a reference
voltage. In these cases, we only need the voltage and not a handle to
the regulator. Another common pattern is for chips to have an internal
reference voltage that is used when an external reference is not
available. There are also a few drivers outside of IIO that do the same.
So we would like to propose a new regulator consumer API to handle these
specific cases to avoid repeating the same boilerplate code in multiple
drivers.
As an example of how these functions are used, I have included a few
patches to consumer drivers. But to avoid a giant patch bomb, I have
omitted the iio/adc and iio/dac patches I have prepared from this
series. I will send those separately but these will add 36 more users
of devm_regulator_get_enable_read_voltage() in addition to the 6 here.
In total, this will eliminate nearly 1000 lines of similar code and will
simplify writing and reviewing new drivers in the future.

Make trylock_page return bool to align the return values of folio_trylock
function and it also corresponds to its comment.

Define yet another DAMOS filter type, YOUNG. Like anon and memcg, the
type of filter will be applied to each page in the memory region, and see
if the page is accessed since the last check. Based on the 'matching'
parameter, the page is filtered out or in.
Note that this commit is adding only the type definition. The
implementation should be made by DAMON operations sets. A commit for the
implementation on 'paddr' DAMON operations set will follow.
