There is no need to print on each unsuccessful matcher
ip_version combination since it probably will happen when
trying to create all the possible combinations.
On a real failure we have a print in the calling function.

The concept of Relaxed Ordering in the PCI Express environment allows
switches in the path between the Requester and Completer to reorder some
transactions just received before others that were previously enqueued.
In ETH driver, there is no question of write integrity since each memory
segment is written only once per cycle. In addition, the driver doesn't
access the memory shared with the hardware until the corresponding CQE
arrives indicating all PCI transactions are done.
Running TCP single stream over ConnectX-4 LX, ARM CPU on remote-numa has
300% improvement in the bandwidth.
With relaxed ordering turned off: BW:10 [GB/s]
With relaxed ordering turned on: BW:40 [GB/s]
The driver turns relaxed ordering with respect to the firmware
capabilities and the return value from pcie_relaxed_ordering_enabled().

Instead of exposing the RQ datapath handlers (from en_rx.c) so that
they are set in the control path (in en_main.c), wrap this logic
in a single function in en_rx.c and expose it alone.
Every profile will now have a pointer to the new mlx5e_rx_handlers
structure, instead of directly pointing to the previously-exposed
RQ handlers.
This significantly improves locality and modularity of the driver,
and allows many functions in en_rx.c to become static.

Currently PF and VF representors are exposed as virtual device.
They are not linked to its parent PCI device like how uplink
representor is linked.
Due to this, PF and VF representors cannot benefit of the
systemd defined naming scheme. This requires special handling
by the users.
Hence, link the PF and VF representors to their parent PCI device
similar to existing uplink representor netdevice.
Example:
udevadm output before linking to PCI device:
$ udevadm test-builtin net_id /sys/class/net/eth6
Load module index
Network interface NamePolicy= disabled on kernel command line, ignoring.
Parsed configuration file /usr/lib/systemd/network/99-default.link
Created link configuration context.
Using default interface naming scheme 'v243'.
ID_NET_NAMING_SCHEME=v243
Unload module index
Unloaded link configuration context.
udevadm output after linking to PCI device:
$ udevadm test-builtin net_id /sys/class/net/eth6
Load module index
Network interface NamePolicy= disabled on kernel command line, ignoring.
Parsed configuration file /usr/lib/systemd/network/99-default.link
Created link configuration context.
Using default interface naming scheme 'v243'.
ID_NET_NAMING_SCHEME=v243
ID_NET_NAME_PATH=enp0s8f0npf0vf0
Unload module index
Unloaded link configuration context.
In past there was little concern over seeing 10,000 lines output
showing up at thread [1] is not applicable as ndo ops for VF
handling is not exposed for all the 100 repesentors for mlx5 devices.
Additionally alternative device naming [2] to overcome shorter device
naming is also part of the latest systemd release v245.

Currently steering table and rx group initialization helper

Per page request event, FW request to allocated or release pages for a
single function. Driver maintains FW pages object per function, so there
is no need to hold one global page data-base. Instead, have a page
data-base per function, which will improve performance release flow in all
cases, especially for "release all pages".
As the range of function IDs is large and not sequential, use xarray to
store a per function ID page data-base, where the function ID is the key.
Upon first allocation of a page to a function ID, create the page
data-base per function. This data-base will be released only at pagealloc
mechanism cleanup.
NIC: ConnectX-4 Lx
CPU: Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz
Test case: 32 VFs, measure release pages on one VF as part of FLR
Before: 0.021 Sec
After: 0.014 Sec
The improvement depends on amount of VFs and memory utilization
by them. Time measurements above were taken from idle system.

Thanks to Okash's latest work, the TODO list is essentially empty, so
the way out from staging now seems open.
The status of the remaining issue mentioned in TODO is not clear, we
asked the speakup user mailing list for reproducer cases, but didn't get
a really specific scenario. One serious bug was fixed by 9d32c0cde4e2
("staging/speakup: fix get_word non-space look-ahead"), which does not
seem to really be related to the bug mentioned in TODO. Possibly the bug
mentioned in TODO has been fixed long ago and people have been thinking
that it was not because they can not distinguish the symptoms mentioned
in TODO from the symptoms of the bug fixed by 9d32c0cde4e2.

For some reason they tend to squat on the very first CSR/
Cambridge Silicon Radio VID/PID instead of paying fees.
This is an extremely common problem; the issue goes as back as 2013
and these devices are only getting more popular, even rebranded by
reputable vendors and sold by retailers everywhere.
So, at this point in time there are hundreds of modern dongles reusing
the ID of what originally was an early Bluetooth 1.1 controller.
Linux is the only place where they don't work due to spotty checks
in our detection code. It only covered a minimum subset.
So what's the big idea? Take advantage of the fact that all CSR
chips report the same internal version as both the LMP sub-version and
HCI revision number. It always matches, couple that with the manufacturer
code, that rarely lies, and we now have a good idea of who is who.
Additionally, by compiling a list of user-reported HCI/lsusb dumps, and
searching around for legit CSR dongles in similar product ranges we can
find what CSR BlueCore firmware supported which Bluetooth versions.
That way we can narrow down ranges of fakes for each of them.
e.g. Real CSR dongles with LMP subversion 0x73 are old enough that
support BT 1.1 only; so it's a dead giveaway when some
third-party BT 4.0 dongle reuses it.
So, to sum things up; there are multiple classes of fake controllers
reusing the same 0A12:0001 VID/PID. This has been broken for a while.
Known 'fake' bcdDevices: 0x0100, 0x0134, 0x1915, 0x2520, 0x7558, 0x8891

The glue layer may need to know current available role to do some
setting, eg, the wakeup setting. So we add ci_hdrc_query_available_role
for that.

In case of error, the function clk_register() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().

Power Management Controller (PMC) can override the PLLM clock settings,
including the enable-state. Although PMC could only act as a second level
gate, meaning that PLLM needs to be enabled by the Clock and Reset
Controller (CaR) anyways if we want it to be enabled. Hence, when PLLM is
overridden by PMC, it needs to be enabled by CaR and ungated by PMC in
order to be functional. Please note that this patch doesn't fix any known
problem, and thus, it's merely a minor improvement.

The RTC unit in the Ingenic SoCs has two clock sources, one
is from an external 32.768kHz clock, and the other is from an
external 24MHz/48MHz main clock that is divided by 512. The
choice of these two clocks is controlled by the ERCS bit in
the OPCR register. The RNG unit will also use this clock.

clang static analysis flags this error
88pm860x_battery.c:522:19: warning: Assigned value is
garbage or undefined [core.uninitialized.Assign]
info->start_soc = soc;
^ ~~~
soc is set by calling calc_soc.
But calc_soc can return without setting soc.
So check the return status and bail similarly to other
checks in pm860x_init_battery and initialize soc to
silence the warning.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Some Buffalo LinkStations perform the power off operation, at restart
time, depending on the state of an output pin (LED2/INTn) at the ethernet
PHY. This pin is also used to wake the machine when a WoL packet is
received by the PHY.
The driver is required by the Buffalo LinkStation LS421DE (ARM MVEBU),
and other models. Without it, the board remains forever halted if a
power off command is executed, unless the PSU is disconnected and
connected again.
Add the driver to provide the power off function and also make the WoL
feature to be available.
