test_xdp_meta.sh can't be used by the BPF CI.
Migrate test_xdp_meta.sh in a new test case in xdp_context_test_run.c.
It uses the same BPF programs located in progs/test_xdp_meta.c and the
same network topology.
Remove test_xdp_meta.sh and its Makefile entry.

Currently, user needs to manually enable transmit hardware timestamp
feature of certain Ethernet drivers, e.g. stmmac and igc drivers, through
following command after running the xdp_hw_metadata app.
sudo hwstamp_ctl -i eth0 -t 1
To simplify the step test of xdp_hw_metadata, set tx_type to HWTSTAMP_TX_ON
to enable hardware timestamping for all outgoing packets, so that user no
longer need to execute hwstamp_ctl command.

Essentially reverse the order of headers for userspace generated files.

This happens on 64-bit big-endian machines.
SO_RCVLOWAT requires an int parameter. However, instead of int, the test
uses unsigned long in one place and size_t in another. Both are 8 bytes
long on 64-bit machines. The kernel, having received the 8 bytes, doesn't
test for the exact size of the parameter, it only cares that it's >=
sizeof(int), and casts the 4 lower-addressed bytes to an int, which, on
a big-endian machine, contains 0. 0 doesn't trigger an error, SO_RCVLOWAT
returns with success and the socket stays with the default SO_RCVLOWAT = 1,
which results in vsock_test failures, while vsock_perf doesn't even notice
that it's failed to change it.

The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.

Currently, there is an inconsistency in how graphics sysfs knobs are

read, while graphics frequency sysfs knobs are opened once and remain
open until turbostat exits. This inconsistency is confusing and adds

reusing the file pointers for subsequent accesses. This approach

In various generations, platforms often share a majority of features,
diverging only in a few specific aspects. The current approach of using
hardcoded values in 'platform_features' structure fails to effectively
represent these divergences.
To improve the description of platform divergence:
1. Each newly introduced 'platform_features' structure must have a base,
typically derived from the previous generation.
2. Platform feature values should be inherited from the base structure
rather than being hardcoded.
This approach ensures a more accurate and maintainable representation of
platform-specific features across different generations.
Converts `adl_features` and `lnl_features` to follow this new scheme.

parse_cpu_string() parses the string input either from command line or
from /sys/fs/cgroup/cpuset.cpus.effective to get a list of CPUs that
turbostat can run with.
The cpu string returned by /sys/fs/cgroup/cpuset.cpus.effective contains
a trailing '\n', but strtoul() fails to treat this as an error.
That says, for the code below
val = ("\n", NULL, 10);
val returns 0, and errno is also not set.
As a result, CPU0 is erroneously considered as allowed CPU and this
causes failures when turbostat tries to run on CPU0.
get_counters: Could not migrate to CPU 0

turbostat: re-initialized with num_cpus 8, allowed_cpus 5

platforms
Intel hybrid platforms expose different perf devices for P and E cores.
Instead of one, "/sys/bus/event_source/devices/cpu" device, there are
"/sys/bus/event_source/devices/{cpu_core,cpu_atom}".
This, however makes it more complicated for the user,
because most of the counters are available on both and had to be
handled manually.
This patch allows users to use "virtual" cpu device that is seemingly
translated to cpu_core and cpu_atom perf devices, depending on the type
of a CPU we are opening the counter for.

Pull char/misc/IIO/whatever driver subsystem updates from Greg KH:
"Here is the 'big and hairy' char/misc/iio and other small driver
subsystem updates for 6.13-rc1.
Loads of things in here, and even a fun merge conflict!
- rust misc driver bindings and other rust changes to make misc
drivers actually possible.
I think this is the tipping point, expect to see way more rust
drivers going forward now that these bindings are present. Next
merge window hopefully we will have pci and platform drivers
working, which will fully enable almost all driver subsystems to
start accepting (or at least getting) rust drivers.
This is the end result of a lot of work from a lot of people,
congrats to all of them for getting this far, you've proved many of
us wrong in the best way possible, working code :)
- IIO driver updates, too many to list individually, that subsystem
keeps growing and growing...
- Interconnect driver updates
- nvmem driver updates
- pwm driver updates
- platform_driver::remove() fixups, loads of them
- counter driver updates
- misc driver updates (keba?)
- binder driver updates and fixes
- loads of other small char/misc/etc driver updates and additions,
full details in the shortlog.
All of these have been in linux-next for a while, with no other
reported issues other than that merge conflict"

"Three fixes, the main one build that we build the kallsyms test

bpftool now embeds the kfuncs definitions directly in the generated
vmlinux.h
This is great, but because the selftests dir might be compiled with
HID_BPF disabled, we have no guarantees to be able to compile the
sources with the generated kfuncs.
If we have the kfuncs, because we have the `__not_used` hack, the newly
defined kfuncs do not match the ones from vmlinux.h and things go wrong.
Prevent vmlinux.h to define its kfuncs and also add the missing `__weak`
symbols for our custom kfuncs definitions

The parameter passed to load_mod() is stored in $MOD, but never used.
Obviously it was intended to be used instead of the hardcoded
"test_kallsyms_b" module name.

Pull modules updates from Luis Chamberlain:
- The whole caching of module code into huge pages by Mike Rapoport is
going in through Andrew Morton's tree due to some other code
dependencies. That's really the biggest highlight for Linux kernel
modules in this release. With it we share huge pages for modules,
starting off with x86. Expect to see that soon through Andrew!
- Helge Deller addressed some lingering low hanging fruit alignment
enhancements by. It is worth pointing out that from his old patch
series I dropped his vmlinux.lds.h change at Masahiro's request as he
would prefer this to be specified in asm code [0].
[0] https://lore.kernel.org/all/20240129192644.3359978-5-mcgrof@kernel.org/T/#m9efef5e700fbecd28b7afb462c15eed8ba78ef5a
- Matthew Maurer and Sami Tolvanen have been tag teaming to help get us
closer to a modversions for Rust. In this cycle we take in quite a
lot of the refactoring for ELF validation. I expect modversions for
Rust will be merged by v6.14 as that code is mostly ready now.
- Adds a new modules selftests: kallsyms which helps us tests
find_symbol() and the limits of kallsyms on Linux today.
- We have a realtime mailing list to kernel-ci testing for modules now
which relies and combines patchwork, kpd and kdevops:
https://patchwork.kernel.org/project/linux-modules/list/
https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/README.md
https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/kernel-ci-kpd.md
https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/linux-modules-kdevops-ci.md
If you want to help avoid Linux kernel modules regressions, now its
simple, just add a new Linux modules sefltests under
tools/testing/selftests/module/ That is it. All new selftests will be
used and leveraged automatically by the CI.
