This registers custom sysfs properties using the native functionality
of the power-supply framework, which cleans up the code a bit and
fixes a race-condition. Before this patch the sysfs attributes were
not properly registered to udev.

A previous commit moved the ether_addr_copy() in i40e_set_mac() before
the mac filter del/add to avoid a race. However it wasn't taken into
account that this alters the mac address being handed to
i40e_del_mac_filter().
Also changed i40e_add_mac_filter() to operate on netdev->dev_addr,
hopefully that makes the code easier to read.

In the ioctl_event_ctl() SWITCHTEC_IOCTL_EVENT_IDX_ALL case, we call
event_ctl() several times with the same "ctl" struct. Each call clobbers
ctl.flags, which leads to the problem that we may not actually enable or
disable all events as the user requested.
Preserve the event flag value with a temporary variable.

After submitting a Firmware Download MRPC command, Switchtec firmware will
delay Management EP BAR MemRd TLP responses by more than 10ms. This is a
firmware limitation. Delayed MemRd completions are a problem for systems
with a low Completion Timeout (CTO).
The current driver checks the MRPC status immediately after submitting an
MRPC command, which results in a delayed MemRd completion that may cause a
Completion Timeout.
Remove the immediate status check and rely on the check after receiving an
interrupt or timing out.
This is only a software workaround to the READ issue and a proper fix of
this should be done in firmware.

Ignore acpi_device_fix_up_power() return value. If we return an error
we end up with acpi_default_enumeration() still creating a platform-
device for the device and we end up with the device still being used
but without the special LPSS related handling which is not useful.
Specicifically ignoring the error fixes the touchscreen no longer
working after a suspend/resume on a Prowise PT301 tablet.
This tablet has a broken _PS0 method on the touchscreen's I2C controller,
causing acpi_device_fix_up_power() to fail, causing fallback to standard
platform-dev handling and specifically causing acpi_lpss_save/restore_ctx
to not run.
The I2C controllers _PS0 method does actually turn on the device, but then
does some more nonsense which fails when run during early boot trying to
use I2C opregion handling on another not-yet registered I2C controller.

Add two new metrics for CPU idle states, "above" and "below", to count
the number of times the given state had been asked for (or entered
from the kernel's perspective), but the observed idle duration turned
out to be too short or too long for it (respectively).
These metrics help to estimate the quality of the CPU idle governor
in use.

a9c8088c7988 ("i2c: i801: Don't restore config registers on runtime PM")
nullified the runtime PM suspend/resume callback pointers while keeping the
runtime PM enabled.
This caused the SMBus PCI device to stay in D0 with
/sys/devices/.../power/runtime_status showing "error" when the runtime PM
framework attempted to autosuspend the device. This is due to PCI bus
runtime PM, which checks for driver runtime PM callbacks and returns
-ENOSYS if they are not set.
Since i2c-i801.c doesn't need to do anything device-specific for runtime
PM, Jean Delvare proposed this be fixed in the PCI core rather than adding
dummy runtime PM callback functions in the PCI drivers.
Change pci_pm_runtime_suspend()/pci_pm_runtime_resume() so they allow
changing the PCI device power state during runtime PM transitions even if
the driver supplies no runtime PM callbacks.
This fixes the runtime PM regression on i2c-i801.c.
It is not obvious why the code previously required the runtime PM
callbacks. The test has been there since the code was introduced by
6cbf82148ff2 ("PCI PM: Run-time callbacks for PCI bus type").
On the other hand, a similar change was done to generic runtime PM
callbacks in 05aa55dddb9e ("PM / Runtime: Lenient generic runtime pm
callbacks").

[Why]
Legacy cursor plane updates from drm helpers go through the full
atomic codepath. A high volume of cursor updates through this slow
code path can cause subsequent page-flips to skip vblank intervals
since each individual update is slow.
This problem is particularly noticeable for the compton compositor.
[How]
A fast path for cursor plane updates is added by using DRM asynchronous
commit support provided by async_check and async_update. These don't do
a full state/flip_done dependency stall and they don't block other
commit work.
However, DC still expects itself to be single-threaded for anything
that can issue register writes. Screen corruption or hangs can occur
if write sequences overlap. Every call that potentially perform
register writes needs to be guarded for asynchronous updates to work.
The dc_lock mutex was added for this.

In commit 61d792562b53 ("vfio-pci: Use mutex around open, release, and
remove") a mutex was added to freeze the refcnt for a device so that
we can handle errors and perform bus resets on final close. However,
bus resets can be rather slow and a global mutex here is undesirable.
Evaluating the potential locking granularity, a per-device mutex
provides the best resolution but with multiple devices on a bus all
released concurrently, they'll race to acquire each other's mutex,
likely resulting in no reset at all if we use trylock. We therefore
lock at the granularity of the bus/slot reset as we're only attempting
a single reset for this group of devices anyway. This allows much
greater scaling as we're bounded in the number of devices protected by
a single reflck object.

adc5_get_dt_data uses a local, prop, feeds it to adc5_get_dt_channel_data,
and then puts the result into adc->chan_props. The problem is
adc5_get_dt_channel_data may not initialize that structure fully, so a

not defined in DT. adc5_read_raw then uses this as an array index,

Unfortunately, when I went to add the initializer for this and tried to

When support for bonding of RoCE devices was added, there was
necessarily a link between the RoCE device and the paired netdevice that
was part of the bond. If you remove the mlx4_en module, that paired
association is broken (the RoCE device is still present but the paired
netdevice has been released). We need to account for this in
is_upper_ndev_bond_master_filter() and filter out those links with a
broken pairing or else we later oops in netdev_next_upper_dev_rcu().

The Video Engine (VE) embedded in the Aspeed AST2400 and AST2500 SOCs
can capture and compress video data from digital or analog sources. With
the Aspeed chip acting a service processor, the Video Engine can capture
the host processor graphics output.
Add a V4L2 driver to capture video data and compress it to JPEG images.
Make the video frames available through the V4L2 streaming interface.

The regulator supports a dedicated suspend mode.
Implement the appropriate ->set_suspend_xx() hooks, add support for
->set_mode(), and provide basic PM ops functionalities to setup the
regulator in a suspend state when the system is entering suspend.
