8a3629a6a9 arm64: dts: ti: k3-j784s4-evm-quad-port-eth-exp1: Remove duplicate hogs
The j784s4-evm board dts now has the gpio hogs for MUX2 after integration
of audio support. Remove duplicate gpio-hogs from the overlay dtso to
prevent mux probe failures leading to can-phy3 deferred probe:
'gpio-mux mux-controller: probe with driver gpio-mux failed with error -16'

peripherals from main domain.

This also makes it consistent with the rest of the k3 platforms where

1f4c7f3b3a Merge patch series "Split devres APIs to device/devres.h and introduce devm_kmemdup_array()"
Raag Jadav <raag.jadav@intel.com> says:

This series

1. Splits device/devres.h for the users that are only interested in devres APIs.
   Original work by Andy Shevchenko:
   https://lore.kernel.org/r/20241203195340.855879-1-andriy.shevchenko@linux.intel.com

2. Introduces a more robust and cleaner devm_kmemdup_array() helper and uses it
   across drivers.

The idea behind embedding both work into a single series is to make the review
process easier and reduce conflicts while merging.

a21cad9312 driver core: Split devres APIs to device/devres.h
device.h is a huge header which is hard to follow and easy to miss
something. Improve that by splitting devres APIs to device/devres.h.

In particular this helps to speedup the build of the code that includes
device.h solely for a devres APIs.

While at it, cast the error pointers to __iomem using IOMEM_ERR_PTR()
and fix sparse warnings.

80b6ef8ae2 drm/amdgpu: Pop jobs from the queue more robustly
Replace a copy of DRM scheduler's to_drm_sched_job with a copy of a newly
added drm_sched_entity_queue_pop.

This allows breaking the hidden dependency that queue_node has to be the
first element in struct drm_sched_job.

A comment is also added with a reference to the mailing list discussion
explaining the copied helper will be removed when the whole broken
amdgpu_job_stop_all_jobs_on_sched is removed.

b6eb664d89 drm/sched: Add internal job peek/pop API
Idea is to add helpers for peeking and popping jobs from entities with
the goal of decoupling the hidden assumption in the code that queue_node
is the first element in struct drm_sched_job.

That assumption usually comes in the form of:

  while ((job = to_drm_sched_job(spsc_queue_pop(&entity->job_queue))))

Which breaks if the queue_node is re-positioned due to_drm_sched_job
being implemented with a container_of.

This also allows us to remove duplicate definitions of to_drm_sched_job.

f15176b8b6 net: dsa: rtl8366rb: Fix compilation problem
When the kernel is compiled without LED framework support the
rtl8366rb fails to build like this:

rtl8366rb.o: in function `rtl8366rb_setup_led':
rtl8366rb.c:953:(.text.unlikely.rtl8366rb_setup_led+0xe8):
  undefined reference to `led_init_default_state_get'
rtl8366rb.c:980:(.text.unlikely.rtl8366rb_setup_led+0x240):
  undefined reference to `devm_led_classdev_register_ext'

As this is constantly coming up in different randconfig builds,
bite the bullet and create a separate file for the offending
code, split out a header with all stuff needed both in the
core driver and the leds code.

Add a new bool Kconfig option for the LED compile target, such
that it depends on LEDS_CLASS=y || LEDS_CLASS=RTL8366RB
which make LED support always available when LEDS_CLASS is
compiled into the kernel and enforce that if the LEDS_CLASS
is a module, then the RTL8366RB driver needs to be a module
as well so that modprobe can resolve the dependencies.

Fixes: 32d6170054 ("net: dsa: realtek: add LED drivers for rtl8366rb")

834da3756f HID: bpf: add a v6.11+ compatible BPF fixup for the XPPen ACK05 remote
With v6.11+, we can actually call hid_hw_output_report() and put the device
into raw mode, thus getting accurate events without being messed up.

Technically we could do the same on v6.10, but given that wayland, gnome
and KDE are still not capable of handling the dial, and that v6.10 is EOL,
we can safely save a little bit of compilation by only allowing v6.11+.

We can easily export the battery information to userspace by adding a
dedicated report. However, we need to cheat on the kernel to force it
not to query the battery by making the physical collection a stylus. The
kernel will then only rely on the events it gets from the device.

4a94deb949 HID: bpf: new hid_bpf_async.h common header
The purpose is to simplify the use of bpf_wq to defer blocking
operations in a sleepable context. Compared to a more "classic"
async approach, there is no sync mechanism to wait for the async
to finish.

The "simple" API is the following:

```

static int HID_BPF_ASYNC(async_fun)(struct hid_bpf_ctx *hctx)
{
        bpf_printk("%s", __fun__);
        return 0;
}

SEC("syscall")
int probe(struct hid_bpf_probe_args *ctx)
{
        ctx->retval = HID_BPF_ASYNC_INIT(async_fun);
        return 0;
}

SEC(HID_BPF_DEVICE_EVENT)
int BPF_PROG(event_handler, struct hid_bpf_ctx *hctx)
{
        /* async_fun() can be called now, it's not a sleepable
         * function in this example
         */
        async_fun(hctx);

        /* but we can also delay the call by 10 ms */
        HID_BPF_ASYNC_DELAYED_CALL(async_fun, hctx, 10);

        return 0;
}

HID_BPF_OPS(xppen_ack05_remote) = {
        .hid_device_event = (void *)event_handler,
};
```

43db1911f8 HID: bpf: Suppress bogus F13 trigger on Sirius keyboard full fan shortcut
The TUXEDO Sirius 16 Gen1 and the TUXEDO Sirius 16 Gen2 Notebooks have an
additional "fan" key next to F12.

Pressing it alone sends a F14 key press which can be bound by user space.

Pressing it while holding the FN key triggers two things:
- The EC firmware locks the fan speed of the internal fans at 100%
- F13 key press is registered which by default is already bound in xkb and
  desktop environments (e.g. in KDE Plasma it launches system settings)

To avoid this unexpected double duty of the FN shortcut, this bpf program
suppresses the F13 key press.

56be863932 HID: bpf: Add support for the default firmware mode of the Huion K20
This re-uses the same HID report descriptor that we also use for
the tablet mode after switching the device. The keys send uniquely
identifyable shortcuts so we can map those to buttons.

However the dial and the button inside the dial send events on a
different hidraw node and they are unreliable (e.g. the button does not
get released reliably). So they're ignored in this patch, it's not
worth the effort getting those to work correctly.

e13b6da704 virtio-net: tweak for better TX performance in NAPI mode
There are several issues existed in start_xmit():

- Transmitted packets need to be freed before sending a packet, this
  introduces delay and increases the average packets transmit
  time. This also increase the time that spent in holding the TX lock.
- Notification is enabled after free_old_xmit_skbs() which will
  introduce unnecessary interrupts if TX notification happens on the
  same CPU that is doing the transmission now (actually, virtio-net
  driver are optimized for this case).

So this patch tries to avoid those issues by not cleaning transmitted
packets in start_xmit() when TX NAPI is enabled and disable
notifications even more aggressively. Notification will be since the
beginning of the start_xmit(). But we can't enable delayed
notification after TX is stopped as we will lose the
notifications. Instead, the delayed notification needs is enabled
after the virtqueue is kicked for best performance.

Performance numbers:

1) single queue 2 vcpus guest with pktgen_sample03_burst_single_flow.sh
   (burst 256) + testpmd (rxonly) on the host:

- When pinning TX IRQ to pktgen VCPU: split virtqueue PPS were
  increased 55% from 6.89 Mpps to 10.7 Mpps and 32% TX interrupts were
  eliminated. Packed virtqueue PPS were increased 50% from 7.09 Mpps to
  10.7 Mpps, 99% TX interrupts were eliminated.

- When pinning TX IRQ to VCPU other than pktgen: split virtqueue PPS
  were increased 96% from 5.29 Mpps to 10.4 Mpps and 45% TX interrupts
  were eliminated; Packed virtqueue PPS were increased 78% from 6.12
  Mpps to 10.9 Mpps and 99% TX interrupts were eliminated.

2) single queue 1 vcpu guest + vhost-net/TAP on the host: single
   session netperf from guest to host shows 82% improvement from
   31Gb/s to 58Gb/s, %stddev were reduced from 34.5% to 1.9% and 88%
   of TX interrupts were eliminated.

2bf3caa7cc powerpc/32: Stop printing Kernel virtual memory layout
Printing of Kernel virtual memory layout was added for debug purpose
by commit f637a49e50 ("powerpc: Minor cleanups of kernel virt
address space definitions")

For security reasons, don't display the kernel's virtual memory layout.

Other architectures have removed it through following commits.

Commit 071929dbdd ("arm64: Stop printing the virtual memory layout")
Commit 1c31d4e96b ("ARM: 8820/1: mm: Stop printing the virtual memory layout")
Commit 31833332f7 ("m68k/mm: Stop printing the virtual memory layout")
Commit fd8d0ca256 ("parisc: Hide virtual kernel memory layout")
Commit 681ff0181b ("x86/mm/init/32: Stop printing the virtual memory layout")

Commit 681ff0181b ("x86/mm/init/32: Stop printing the virtual memory
layout") thought x86 was the last one, but in reality powerpc/32 still
had it.

So remove it now on powerpc/32 as well.
