The function kdb_position_cursor() takes in a "prompt" parameter but
never uses it. This doesn't _really_ matter since all current callers
of the function pass the same value and it's a global variable, but
it's a bit ugly. Let's clean it up.
Found by code inspection. This patch is expected to functionally be a
no-op.

mlxsw: Fixes
This patchset fixes an issue with mlxsw driver initialization, and a
memory corruption issue in shared buffer occupancy handling.
v3:
- Drop the core thermal fix, it's not relevant anymore.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The following two shared buffer operations make use of the Shared Buffer
Status Register (SBSR):
# devlink sb occupancy snapshot pci/0000:01:00.0
# devlink sb occupancy clearmax pci/0000:01:00.0
The register has two masks of 256 bits to denote on which ingress /
egress ports the register should operate on. Spectrum-4 has more than
256 ports, so the register was extended by cited commit with a new
'port_page' field.
However, when filling the register's payload, the driver specifies the
ports as absolute numbers and not relative to the first port of the port
page, resulting in memory corruptions [1].
Fix by specifying the ports relative to the first port of the port page.

Cited commit added support for a new reset flow ("all reset") which is
deeper than the existing reset flow ("software reset") and allows the
device's PCI firmware to be upgraded.
In the new flow the driver first tells the firmware that "all reset" is
required by issuing a new reset command (i.e., MRSR.command=6) and then
triggers the reset by having the PCI core issue a secondary bus reset
(SBR).
However, due to a race condition in the device's firmware the device is
not always able to recover from this reset, resulting in initialization
failures [1].
New firmware versions include a fix for the bug and advertise it using a
new capability bit in the Management Capabilities Mask (MCAM) register.
Avoid initialization failures by reading the new capability bit and
triggering the new reset flow only if the bit is set. If the bit is not
set, trigger a normal PCI hot reset by skipping the call to the
Management Reset and Shutdown Register (MRSR).
Normal PCI hot reset is weaker than "all reset", but it results in a
fully operational driver and allows users to flash a new firmware, if
they want to.

Since commit e267a5b3ec ("spi: spi-imx: Use dev_err_probe for failed

For example:
RFI_FREQ_SELECT and RFI_FREQ

To ensure compatibility between user inputs and firmware requirements,
a conversion mechanism is necessary for certain attributes. For instance,
on some platforms, the DLVR frequency must be translated into a predefined
index before being communicated to the firmware. On Lunar Lake platform:
RFI_FREQ_SELECT and RFI_FREQ:
Index 0 corresponds to a DLVR frequency of 2227.2 MHz
Index 1 corresponds to a DLVR frequency of 2140 MHz
Introduce a feature that enables the conversion of values between user
space inputs and firmware-accepted formats. This feature would also
facilitate the reverse process, converting firmware values back into user
friendly display values.
To support this functionality, a model-specific mapping table will be
utilized. When available, this table will provide the necessary
translations between user space values and firmware values, ensuring
seamless communication and accurate settings.

Instead, use the bitmasks of these recent processors as default.

Currently the number of frames sent to the chip in a single USB Request
Block is limited only by the size of the TX buffer, which is 20 KiB.
Testing reveals that as many as 13 frames get aggregated. This is more
than what any of the chips would like to receive. RTL8822CU, RTL8822BU,
and RTL8821CU want at most 3 frames, and RTL8723DU wants only 1 frame
per URB.
RTL8723DU in particular reliably malfunctions during a speed test if it
receives more than 1 frame per URB. All traffic seems to stop. Pinging
the AP no longer works.
Fix this problem by limiting the number of frames sent to the chip in a

Also configure RTL8822CU, RTL8822BU, and RTL8821CU to expect 3 frames
per URB.
RTL8703B may or may not be found in USB devices. Declare that it wants

Now that the driver core allows for struct class to be in read-only
memory, we should make all 'class' structures declared at build time
placing them into read-only memory, instead of having to be dynamically
allocated at runtime.

- Fix technically benign bug in __kvm_handle_hva_range() where KVM consumes
the return from a void-returning function as if it were a boolean.

The GPIO reset controller uses gpiolib but there is no Kconfig
dependency reflecting this fact, add one.
With the addition of the controller to the arm64 defconfig this is
causing build breaks for arm64 virtconfig in -next:
