Pull more io_uring updates from Jens Axboe:
"This adds support for IORING_CQE_F_SOCK_NONEMPTY for io_uring accept
requests.
This is very similar to previous work that enabled the same hint for
doing receives on sockets. By far the majority of the work here is
refactoring to enable the networking side to pass back whether or not
the socket had more pending requests after accepting the current one,
the last patch just wires it up for io_uring.
Not only does this enable applications to know whether there are more
connections to accept right now, it also enables smarter logic for
io_uring multishot accept on whether to retry immediately or wait for
a poll trigger"

Commit 1a7d0890dd4a ("kprobe/ftrace: bail out if ftrace was killed")
introduced a bad K&R function definition, which we haven't accepted in a
long long time.
Gcc seems to let it slide, but clang notices with the appropriate error:
kernel/kprobes.c:1140:24: error: a function declaration without a prototype is deprecated in all >
1140 | void kprobe_ftrace_kill()
| ^
| void
but this commit was apparently never in linux-next before it was sent
upstream, so it didn't get the appropriate build test coverage.

Pull tracing tool updates from Steven Rostedt:
"Specific for timerlat:
- Improve the output of timerlat top by adding a missing \n, and by
avoiding printing color-formatting characters where they are
translated to regular characters.
- Improve timerlat auto-analysis output by replacing '\t' with spaces
to avoid copy-and-paste issues when reporting problems.
- Make the user-space (-u) option the default, as it is the most
complete test. Add a -k option to use the in-kernel workload.
- On timerlat top and hist, add a summary with the overall results.
For instance, the minimum value for all CPUs, the overall average
and the maximum value from all CPUs.
- timerlat hist was printing initial values (i.e., 0 as max, and ~0
as min) if the trace stopped before the first Ret-User event. This
problem was fixed by printing the " - " no value string to the
output if that was the case.
For all RTLA tools:
- Add a --warm-up <seconds> option, allowing the workload to run for
<seconds> before starting to collect results.
- Add a --trace-buffer-size option, allowing the user to set the
tracing buffer size for -t option. This option is mainly useful for
reducing the trace file. Now rtla depends on libtracefs >= 1.6.
- Fix the -t [trace_file] parsing, now it does not require the '='
before the option parameter, and better handles the multiple ways a
user can pass the trace_file.txt"

Pull tracing user-event updates from Steven Rostedt:
- Minor update to the user_events interface
The ABI of creating a user event states that the fields are separated
by semicolons, and spaces should be ignored.
But the parsing expected at least one space to be there (which was
incorrect). Fix the reading of the string to handle fields separated
by semicolons but no space between them.
This does extend the API sightly as now "field;field" will now be
parsed and not cause an error. But it should not cause any regressions
as no logic should expect it to fail.
Note, that the logic that parses the event fields to create the
trace_event works with no spaces after the semi-colon. It is
the logic that tests against existing events that is inconsistent.
This causes registering an event without using spaces to succeed
if it doesn't exist, but makes the same call that tries to register
to the same event, but doesn't use spaces, fail.

Pull tracing ring buffer updates from Steven Rostedt:
"Add ring_buffer memory mappings.
The tracing ring buffer was created based on being mostly used with
the splice system call. It is broken up into page ordered sub-buffers
and the reader swaps a new sub-buffer with an existing sub-buffer
that's part of the write buffer. It then has total access to the
swapped out sub-buffer and can do copyless movements of the memory
into other mediums (file system, network, etc).
The buffer is great for passing around the ring buffer contents in the
kernel, but is not so good for when the consumer is the user space
task itself.
A new interface is added that allows user space to memory map the ring
buffer. It will get all the write sub-buffers as well as reader
sub-buffer (that is not written to). It can send an ioctl to change
which sub-buffer is the new reader sub-buffer.
The ring buffer is read only to user space. It only needs to call the
ioctl when it is finished with a sub-buffer and needs a new sub-buffer
that the writer will not write over.
A self test program was also created for testing and can be used as an
example for the interface to user space. The libtracefs (external to
the kernel) also has code that interacts with this, although it is
disabled until the interface is in a official release. It can be
enabled by compiling the library with a special flag. This was used
for testing applications that perform better with the buffer being
mapped.
Memory mapped buffers have limitations. The main one is that it can
not be used with the snapshot logic. If the buffer is mapped,
snapshots will be disabled. If any logic is set to trigger snapshots
on a buffer, that buffer will not be allowed to be mapped"

Pull sysctl updates from Joel Granados:
- Remove sentinel elements from ctl_table structs in kernel/*
Removing sentinels in ctl_table arrays reduces the build time size
and runtime memory consumed by ~64 bytes per array. Removals for
net/, io_uring/, mm/, ipc/ and security/ are set to go into mainline
through their respective subsystems making the next release the most
likely place where the final series that removes the check for
proc_name == NULL will land.
This adds to removals already in arch/, drivers/ and fs/.
- Adjust ctl_table definitions and references to allow constification
- Remove unused ctl_table function arguments
- Move non-const elements from ctl_table to ctl_table_header
- Make ctl_table pointers const in ctl_table_root structure
Making the static ctl_table structs const will increase safety by
keeping the pointers to proc_handler functions in .rodata. Though no
ctl_tables where made const in this PR, the ground work for making
that possible has started with these changes sent by Thomas
Weißschuh.

sdma_v7_0_ring_set_wptr
This commit removes a duplicate check for *is_queue_unmap in the

The following commit updated gmc->noretry from 0 to 1 for GC HW IP
9.3.0:
commit 5f3854f1f4e2 ("drm/amdgpu: add more cases to noretry=1")
This causes the device to hang when a page fault occurs, until the
device is rebooted. Instead, revert back to gmc->noretry=0 so the device
is still responsive.

If a Radeon 6750M GPU from an iMac12,1 is installed into an
iMac 12,2, there is no backlight device initialized during
boot. Everything else is functional, but the display brightness
cannot be controlled. There are no directories present in
/sys/class/backlight after booting. A simple one line
modification to an if statement fixes this issue by initializing
the radeon backlight device for an iMac12,2 as well if it has a
6750M. After the patch, brightness can be controlled and
radeon_bl0 is present in /sys/class/backlight. This was tested
by compiling the latest kernel with and without the patch.
