There is no need to set the pahole v1.25-only flags in an
"ifeq" version clause; we are already in a <= v1.25 branch
of "ifeq", so that combined with a "test-ge" v1.25 ensures the
flags will be applied for v1.25 only.

With pre-generated vmlinux.h there is no dependency on neither vmlinux
nor bootstrap bpftool. Define dependencies separately for both modes.
This avoids needless rebuilds in some corner cases.

Sort bpftool c dump output; aiming to simplify vmlinux.h diffing and
forcing more natural type definitions ordering.
Definitions are sorted first by their BTF kind ranks, then by their base
type name and by their own name.
Type ranks
Assign ranks to btf kinds (defined in function btf_type_rank) to set
next order:
1. Anonymous enums/enums64
2. Named enums/enums64
3. Trivial types typedefs (ints, then floats)
4. Structs/Unions
5. Function prototypes
6. Forward declarations
Type rank is set to maximum for unnamed reference types, structs and
unions to avoid emitting those types early. They will be emitted as
part of the type chain starting with named type.
Lexicographical ordering
Each type is assigned a sort_name and own_name.
sort_name is the resolved name of the final base type for reference
types (typedef, pointer, array etc). Sorting by sort_name allows to
group typedefs of the same base type. sort_name for non-reference type
is the same as own_name. own_name is a direct name of particular type,
is used as final sorting step.

"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"

__raw_cpu_write() with !USE_X86_SEG_SUPPORT config uses read/write
operand constraint modifier "+" for its memory location. This signals
the compiler that the location is both read and written by the asm.
This is not true, because MOV insn only writes to the output.
Correct the modifier to "=" to inform the compiler that the memory
location is only written to. This also prevents the compiler from
value tracking the undefined value from the uninitialized memory.

introduced a bad K&R function definition, which we haven't accepted in a

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 >

- Improves timerlat auto-analysis output by replacing '\t'

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

- 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.

- 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.

Summary
* Removed 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 PR adds
to removals already in arch/, drivers/ and fs/.
* Adjusted ctl_table definitions and references to allow constification
Adjustments:
- Removing unused ctl_table function arguments
- Moving non-const elements from ctl_table to ctl_table_header
- Making 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.
Testing
* These changes went into linux-next after v6.9-rc4; giving it a good month of
testing.

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.
