When the tcm_loop_nr_hw_queues is set to a value greater than 1, the
tags of requests in the block layer are no longer unique. This may lead
to erroneous aborting of commands with the same tag. The issue can be
resolved by using blk_mq_unique_tag to generate globally unique
identifiers by combining the hardware queue index and per-queue tags.

Commit 32566a6f1ae5 ("scsi: lpfc: Remove NLP_RELEASE_RPI flag from nodelist
structure") introduced a regression with SLI-3 adapters (e.g. LPe12000 8Gb)
where a Link Down / Link Up such as caused by disabling an host FC switch
port would result in the devices remaining in the transport-offline state
and multipath reporting them as failed. This problem was not seen with
newer SLI-4 adapters.
The problem was caused by portions of the patch which removed the functions
__lpfc_sli_rpi_release() and lpfc_sli_rpi_release() and all their callers.
This was presumably because with the removal of the NLP_RELEASE_RPI flag
there was no need to free the rpi.
However, __lpfc_sli_rpi_release() and lpfc_sli_rpi_release() which calls it
reset the NLP_UNREG_INP flag. And, lpfc_sli_def_mbox_cmpl() has a path
where __lpfc_sli_rpi_release() was called in a particular case where
NLP_UNREG_INP was not otherwise cleared because of other conditions.
Restoring the else clause of this conditional and simply clearing the
NLP_UNREG_INP flag appears to resolve the problem with SLI-3 adapters. It
should be noted that the code path in question is not specific to SLI-3,
but there are other SLI-4 code paths which may have masked the issue.

At present, we determine the protocol through the cmd type, but other cmd
types, such as vendor-specific commands, default to the PIO protocol. This
strategy often causes the execution of different vendor-specific commands
to fail. In fact, for these commands, a better way is to use the protocol
configured by the command's tf to determine its protocol.

While the network device is registered, it is published to userspace,
and thus userspace can change its state. This means calling
functions such as stmmac_stop_all_dma() and stmmac_mac_set() are
racy.
Moreover, unregister_netdev() will unpublish the network device, and
then if appropriate call the .ndo_stop() method, which is
stmmac_release(). This will first call phylink_stop() which will
synchronously take the link down, resulting in stmmac_mac_link_down()
and stmmac_mac_set(, false) being called.
stmmac_release() will also call stmmac_stop_all_dma().
Consequently, neither of these two functions need to called prior
to unregister_netdev() as that will safely call paths that will
result in this work being done if necessary.
Remove these redundant racy calls.

Lenovo ThinkPad Hybrid USB-C with USB-A Dock (17ef:a359) is affected by
the same problem as the Lenovo Powered USB-C Travel Hub (17ef:721e):
Both are based on the Realtek RTL8153B chip used to use the cdc_ether
driver. However, using this driver, with the system suspended the device
constantly sends pause-frames as soon as the receive buffer fills up.
This causes issues with other devices, where some Ethernet switches stop
forwarding packets altogether.
Using the Realtek driver (r8152) fixes this issue. Pause frames are no
longer sent while the host system is suspended.

Rename 'cpu_addr' to 'parent_bus_addr' in the DesignWare ATU configuration.
The ATU translates parent bus addresses to PCI addresses, which are often
the same as CPU addresses but can differ in systems where the bus fabric
translates addresses before passing them to the PCIe controller. This
renaming clarifies the purpose and avoids confusion.

The msg_res region translates writes into PCIe Message TLPs. Previously we
mapped this region using atu.cpu_addr, the input address programmed into
the ATU.
"cpu_addr" is a misnomer because when a bus fabric translates addresses
between the CPU and the ATU, the ATU input address is different from the
CPU address. A future patch will rename "cpu_addr" and correct the value
to be the ATU input address instead of the CPU physical address.
Map the msg_res region before writing to it using the msg_res resource
start, a CPU physical address.

fwctl provides a fwctl_ops->fw_rpc() callback in order to issue ioctls
to a device. The cxl fwctl driver will start by supporting the CXL
Feature commands: Get Supported Features, Get Feature, and Set Feature.
The fw_rpc() callback provides 'enum fwctl_rpc_scope' parameter where
it indicates the security scope of the call. The Get Supported Features
and Get Feature calls can be executed with the scope of
FWCTL_RPC_CONFIGRATION. The Set Feature call is gated by the effects
of the Feature reported by Get Supported Features call for the specific
Feature.
Only "Get Supported Features" is supported in this patch. Additional
commands will be added in follow on patches. "Get Supported Features"
will filter the Features that are exclusive to the kernel. The flag
field of the Feature details will be cleared of the "Changeable"
field and the "set feat size" will be set to 0 to indicate that
the feature is not changeable.

The new option is CONFIG_NULL_TTY_DEFAULT_CONSOLE.
if enabled, and CONFIG_VT is disabled, ttynull will become the default
primary console device.
ttynull will be the only console device usually with this option enabled.
Some architectures do call add_preferred_console() which may add another
console though.
Motivation:
Many distributions ship with CONFIG_VT enabled. On tested desktop hardware
if CONFIG_VT is disabled, the default console device falls back to
/dev/ttyS0 instead of /dev/tty.
This could cause issues in user space, and hardware problems:
1. The user space issues include the case where /dev/ttyS0 is
disconnected, and the TCGETS ioctl, which some user space libraries use
as a probe to determine if a file is a tty, is called on /dev/console and
fails. Programs that call isatty() on /dev/console and get an incorrect
false value may skip expected logging to /dev/console.
2. The hardware issues include the case if a user has a science instrument
or other device connected to the /dev/ttyS0 port, and they were to upgrade
to a kernel that is disabling the CONFIG_VT option, kernel logs will then
be sent to the device connected to /dev/ttyS0 unless they edit their
kernel command line manually.
The new CONFIG_NULL_TTY_DEFAULT_CONSOLE option will give users and
distribution maintainers an option to avoid this. Disabling CONFIG_VT and
enabling CONFIG_NULL_TTY_DEFAULT_CONSOLE will ensure the default kernel
console behavior is not dependent on hardware configuration by default, and
avoid unexpected new behavior on devices connected to the /dev/ttyS0 serial
port.

'cts' in sdio_uart_check_modem_status() is considered a 'bool', but
typed as signed 'int'. Make it 'bool' so it is clear the code does not
care about the masked value, but true/false.

Currently, scmi_pd_power() explicitly verifies whether the requested
power state was applied by calling state_get(). While this check could
detect failures where the state was not properly updated, ensuring
correctness is the responsibility of the SCMI firmware.
Removing this redundant state_get() call eliminates an unnecessary
round-trip to the firmware, improving efficiency. Any mismatches
between the requested and actual states should be handled by the SCMI
firmware, which must return a failure if state_set() is unsuccessful.
Additionally, in some cases, checking the state after powering off a
domain may be unreliable or unsafe, depending on the firmware
implementation.
This patch removes the redundant verification, simplifying the function
without compromising correctness.

Kconfig treats the dependency as optional, but the header file only provides
normal declarations and no empty API stubs:
ld: fs/btrfs/extent_io.o: in function `writepage_delalloc':

ld: th1520-pm-domains.c:(.text+0x1c6): undefined reference to `th1520_aon_power_update'
Since the firmware code can easily be enabled for compile testing, there
is no need to add stubs either, so just make it a hard dependency.
