The DLCI driver (dlci.c) implements the Frame Relay protocol. However,
we already have another newer and better implementation of Frame Relay
provided by the HDLC_FR driver (hdlc_fr.c).
The DLCI driver's implementation of Frame Relay is used by only one
hardware driver in the kernel - the SDLA driver (sdla.c).
The SDLA driver provides Frame Relay support for the Sangoma S50x devices.
However, the vendor provides their own driver (along with their own
multi-WAN-protocol implementations including Frame Relay), called WANPIPE.
I believe most users of the hardware would use the vendor-provided WANPIPE
driver instead.
(The WANPIPE driver was even once in the kernel, but was deleted in
commit 8db60bcf30 ("[WAN]: Remove broken and unmaintained Sangoma
drivers.") because the vendor no longer updated the in-kernel WANPIPE
driver.)

Kyungmin Park maintained and contributed to some of the upstreamed
S5Pv210 and Exynos4210 machines - as described in commit 10ffa96407
("MAINTAINERS: add maintainer of Samsung Mobile Machine support").
However the entry in maintainers got slightly twisted by
commit 004bbd3c01 ("MAINTAINERS: remove non existent files") -
the directory matching pattern was changed from specific machines to
the entire S5Pv210.
Anyway since long time, all S5Pv210 maintenance is covered by the
Samsung ARM architectures maintainer entry and Krzysztof Kozlowski, so
move Kyungmin Park to the CREDITS.
There was also no activity on LKML regarding other maintained drivers:

opening the doors for easy experimental and deployment-specific
TCP option use.
Reorganize TCP congestion control (CC) initialization to simplify life
of TCP CC implemented in BPF.
Add support for shipping BPF programs with the kernel and loading them
early on boot via the User Mode Driver mechanism, hence reusing all the

My time with MIPS the company has reached its end, and so at best I'll
have little time spend on maintaining arch/mips/.
Ralf last authored a patch over 2 years ago, the last time he committed
one is even further back & activity was sporadic for a while before
that. The reality is that he isn't active.
Having a new maintainer with time to do things properly will be
beneficial all round. Thomas Bogendoerfer has been involved in MIPS
development for a long time & has offered to step up as maintainer, so
add Thomas and remove myself & Ralf from the MIPS entry.
Ralf already has an entry in CREDITS to honor his contributions, so this
just adds one for me.

/* Background. */
For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Userspace also has a hard time figuring out whether a particular flag is
supported on a particular kernel. While it is now possible with
contemporary kernels (thanks to [3]), older kernels will expose unknown
flag bits through fcntl(F_GETFL). Giving a clear -EINVAL during
openat(2) time matches modern syscall designs and is far more
fool-proof.
In addition, the newly-added path resolution restriction LOOKUP flags
(which we would like to expose to user-space) don't feel related to the
pre-existing O_* flag set -- they affect all components of path lookup.
We'd therefore like to add a new flag argument.
Adding a new syscall allows us to finally fix the flag-ignoring problem,
and we can make it extensible enough so that we will hopefully never
need an openat3(2).
/* Syscall Prototype. */
/*
* open_how is an extensible structure (similar in interface to
* clone3(2) or sched_setattr(2)). The size parameter must be set to
* sizeof(struct open_how), to allow for future extensions. All future
* extensions will be appended to open_how, with their zero value
* acting as a no-op default.
*/
struct open_how { /* ... */ };
int openat2(int dfd, const char *pathname,
struct open_how *how, size_t size);
/* Description. */
The initial version of 'struct open_how' contains the following fields:
flags
Used to specify openat(2)-style flags. However, any unknown flag
bits or otherwise incorrect flag combinations (like O_PATH|O_RDWR)
will result in -EINVAL. In addition, this field is 64-bits wide to
allow for more O_ flags than currently permitted with openat(2).
mode
The file mode for O_CREAT or O_TMPFILE.
Must be set to zero if flags does not contain O_CREAT or O_TMPFILE.
resolve
Restrict path resolution (in contrast to O_* flags they affect all
path components). The current set of flags are as follows (at the
moment, all of the RESOLVE_ flags are implemented as just passing
the corresponding LOOKUP_ flag).
RESOLVE_NO_XDEV => LOOKUP_NO_XDEV
RESOLVE_NO_SYMLINKS => LOOKUP_NO_SYMLINKS
RESOLVE_NO_MAGICLINKS => LOOKUP_NO_MAGICLINKS
RESOLVE_BENEATH => LOOKUP_BENEATH
RESOLVE_IN_ROOT => LOOKUP_IN_ROOT
open_how does not contain an embedded size field, because it is of
little benefit (userspace can figure out the kernel open_how size at
runtime fairly easily without it). It also only contains u64s (even
though ->mode arguably should be a u16) to avoid having padding fields
which are never used in the future.
Note that as a result of the new how->flags handling, O_PATH|O_TMPFILE
is no longer permitted for openat(2). As far as I can tell, this has
always been a bug and appears to not be used by userspace (and I've not
seen any problems on my machines by disallowing it). If it turns out
this breaks something, we can special-case it and only permit it for
openat(2) but not openat2(2).
After input from Florian Weimer, the new open_how and flag definitions
are inside a separate header from uapi/linux/fcntl.h, to avoid problems
that glibc has with importing that header.
/* Testing. */
In a follow-up patch there are over 200 selftests which ensure that this
syscall has the correct semantics and will correctly handle several
attack scenarios.
In addition, I've written a userspace library[4] which provides
convenient wrappers around openat2(RESOLVE_IN_ROOT) (this is necessary
because no other syscalls support RESOLVE_IN_ROOT, and thus lots of care
must be taken when using RESOLVE_IN_ROOT'd file descriptors with other
syscalls). During the development of this patch, I've run numerous
verification tests using libpathrs (showing that the API is reasonably
usable by userspace).
/* Future Work. */
Additional RESOLVE_ flags have been suggested during the review period.
These can be easily implemented separately (such as blocking auto-mount
during resolution).
Furthermore, there are some other proposed changes to the openat(2)
interface (the most obvious example is magic-link hardening[5]) which
would be a good opportunity to add a way for userspace to restrict how
O_PATH file descriptors can be re-opened.
Another possible avenue of future work would be some kind of
CHECK_FIELDS[6] flag which causes the kernel to indicate to userspace
which openat2(2) flags and fields are supported by the current kernel
(to avoid userspace having to go through several guesses to figure it
out).

Here is the big char/misc driver patch pull request for 5.1-rc1.
The largest thing by far is the new habanalabs driver for their AI
accelerator chip. For now it is in the drivers/misc directory but will
probably move to a new directory soon along with other drivers of this
type.
Other than that, just the usual set of individual driver updates and
fixes. There's an "odd" merge in here from the DRM tree that they asked
me to do as the MEI driver is starting to interact with the i915 driver,
and it needed some coordination. All of those patches have been
properly acked by the relevant subsystem maintainers.

This patch drops support for AVR32 architecture from the Linux kernel.
The AVR32 architecture is not keeping up with the development of the
kernel, and since it shares so much of the drivers with Atmel ARM SoC,
it is starting to hinder these drivers to develop swiftly.
Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now
Microchip).
Finally, the GCC toolchain is stuck at version 4.2.x, and has not
received any patches since the last release from Atmel;
4.2.4-atmel.1.1.3.avr32linux.1. When building kernel v4.10, this
toolchain is no longer able to properly link the network stack.
Haavard and I have came to the conclusion that we feel keeping AVR32 on
life support offers more obstacles for Atmel ARMs, than it gives joy to
AVR32 users. I also suspect there are very few AVR32 users left today,
if anybody at all.

"The biggest change (by Borislav Petkov) is a thorough rewrite of the
Intel microcode loader and its interactions with the core code.
The biggest conceptual change is the decoupling of the microcode
loading on boot and application processors (which load the microcode
in different scenarios), so that both parse the input patches with as
few assumptions as possible - this also fixes various kernel address
space randomization bugs. (The AP side then goes on and caches the
result to improve boot performance.)
Since the AMD side already did this, this change also opened up the
path towards more unification/simplification of the core microcode
loading infrastructure:

Make it clear that this document, in the kernel, is the master

Also move paragraphs around so as to emphasize dynamic major number

Remove paragraph on 2.6 deprecation, that tag no longer appears

ad5761 is a 1-channel DAC with configurable output range.
The driver uses the regulator interface for its voltage ref.
It shares its register layout with ad5761r, ad5721 and ad5721r.
Differences:
ad5761* are 16 bit, ad5721* are 12 bits.
ad57*1r have an internal reference.

cycle
Core changes:
- It is possible configure groups in debugfs.
- Consolidation of chained IRQ handler install/remove replacing
all call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a
combined call to irq_set_chained_handler_and_data(). This
series was created by Thomas Gleixner after the problem was
observed by Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which
is way cleaner.
- Tglx also wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs
from IRQ numbers. The goal is to get rid of the irq number
from the handlers in the IRQ flow which is nice.
Driver feature enhancements:
- Power management support for the SiRF SoC Atlas 7.
- Power down support for the Qualcomm driver.
- Intel Cherryview and Baytrail: switch drivers to use raw
spinlocks in IRQ handlers to play nice with the realtime
patch set.
- Rework and new modes handling for Qualcomm SPMI-MPP.
- Pinconf power source config for SH PFC.
New drivers and subdrivers:
- A new driver for Conexant Digicolor CX92755.
- A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8,
PH1-Pro5, ProXtream2 and PH1-LD6b SoC pin control support.
- Reverse-egineered the S/PDIF settings for the Allwinner
sun4i driver.
- Support for Qualcomm Technologies QDF2xxx ARM64 SoCs
- A new Freescale i.mx6ul subdriver.
Cleanup:
- Remove platform data support in a number of SH PFC

Adds a new single-purpose PIDs subsystem to limit the number of
tasks that can be forked inside a cgroup. Essentially this is an
implementation of RLIMIT_NPROC that applies to a cgroup rather than a
process tree.
However, it should be noted that organisational operations (adding and
removing tasks from a PIDs hierarchy) will *not* be prevented. Rather,
the number of tasks in the hierarchy cannot exceed the limit through
forking. This is due to the fact that, in the unified hierarchy, attach
cannot fail (and it is not possible for a task to overcome its PIDs
cgroup policy limit by attaching to a child cgroup -- even if migrating
mid-fork it must be able to fork in the parent first).
PIDs are fundamentally a global resource, and it is possible to reach
PID exhaustion inside a cgroup without hitting any reasonable kmemcg
policy. Once you've hit PID exhaustion, you're only in a marginally
better state than OOM. This subsystem allows PID exhaustion inside a
cgroup to be prevented.

- usual driver enhancements, new board additions and misc fixups"
[ NOTE! This merge effective drops commit 4329b93b28 ("of: Reduce
indentation in of_graph_get_next_endpoint").
The of_graph_get_next_endpoint() function was moved and renamed by
commit fd9fdb78a9 ("[media] of: move graph helpers from
drivers/media/v4l2-core to drivers/of"). It was originally called
v4l2_of_get_next_endpoint() and lived in the file
drivers/media/v4l2-core/v4l2-of.c.
In that original location, it was then fixed to support empty port
nodes by commit b9db140c1e ("[media] v4l: of: Support empty port
nodes"), and that commit clashes badly with the dropped "Reduce
intendation" commit. I had to choose one or the other, and decided
that the "Support empty port nodes" commit was more important ]
