Some systems report INTx as not routed by setting pdev->irq to
IRQ_NOTCONNECTED, resulting in a -ENOTCONN error when trying to
setup eventfd signaling. Include this in the set of conditions
for which the PIN register is virtualized to zero.
Additionally consolidate vfio_pci_get_irq_count() to use this
virtualized value in reporting INTx support via ioctl and sanity
checking ioctl paths since pdev->irq is re-used when the device
is in MSI mode.
The combination of these results in both the config space of the
device and the ioctl interface behaving as if the device does not
support INTx.

stmmac_release() calls phylink_stop() and then goes on to call
stmmac_mac_set(, false). However, phylink_stop() will call
stmmac_mac_link_down() before returning, which will do this work.
Remove this unnecessary call.

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.

intel_tsn_lane_is_available()
Fix the warning "warn: missing error code? 'ret'" in the
intel_tsn_lane_is_available() function.
The function now returns 0 to indicate that a TSN lane was found and
returns -EINVAL when it is not found.

Move devm_pci_alloc_host_bridge() to the beginning of dw_pcie_host_init().
devm_pci_alloc_host_bridge() is generic code that doesn't depend on any DWC
resource, so moving it earlier keeps all the subsequent devicetree-related
code together.

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.

The fault object was designed exclusively for hwpt's IO page faults (PRI).
But its queue implementation can be reused for other purposes too, such as
hardware IRQ and event injections to user space.
Meanwhile, a fault object holds a list of faults. So it's more accurate to
call it a "fault queue". Combining the reusing idea above, abstract a new
iommufd_eventq as a common structure embedded into struct iommufd_fault,
similar to hwpt_paging holding a common hwpt.
Add a common iommufd_eventq_ops and iommufd_eventq_init to prepare for an
IOMMUFD_OBJ_VEVENTQ (vIOMMU Event Queue).

Reorder the iommufd_ctx_get and refcount_inc, to keep them symmetrical

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.

The charge input threshold voltage register on the MAX77693 PMIC accepts
four values: 0x0 for 4.3v, 0x1 for 4.7v, 0x2 for 4.8v and 0x3 for 4.9v.
Due to an oversight, the driver calculated the values for 4.7v and above
starting from 0x0, rather than from 0x1 ([(4700000 - 4700000) / 100000]
gives 0).
Add 1 to the calculation to ensure that 4.7v is converted to a register
value of 0x1 and that the other two voltages are converted correctly as
well.

In commit 'cf9d052aa600 ("pinctrl: qcom: Don't clear pending interrupts
when enabling")' Doug establishes an expectation that edge interrupts
occurring while an interrupt is disabled should be delivered once the
interrupt is enabled again.
Implement a test to validate that this is the case.

When submitting the TLMM test driver, Bjorn reported that some of the test
cases are failing for GPIOs that not are backed by PDC (i.e. "non-wakeup"
GPIOs that are handled directly in pinctrl-msm). Basically, lingering
latched interrupt state is still being delivered at IRQ request time, e.g.:
ok 1 tlmm_test_silent_rising
tlmm_test_silent_falling: ASSERTION FAILED at drivers/pinctrl/qcom/tlmm-test.c:178
Expected atomic_read(&priv->intr_count) == 0, but
atomic_read(&priv->intr_count) == 1 (0x1)
not ok 2 tlmm_test_silent_falling
tlmm_test_silent_low: ASSERTION FAILED at drivers/pinctrl/qcom/tlmm-test.c:178
Expected atomic_read(&priv->intr_count) == 0, but
atomic_read(&priv->intr_count) == 1 (0x1)
not ok 3 tlmm_test_silent_low
ok 4 tlmm_test_silent_high
Whether to report interrupts that came in while the IRQ was unclaimed
doesn't seem to be well-defined in the Linux IRQ API. However, looking
closer at these specific cases, we're actually reporting events that do not
match the interrupt type requested by the driver:
1. After "ok 1 tlmm_test_silent_rising", the GPIO is in low state and
configured for IRQF_TRIGGER_RISING.
2. (a) In preparation for "tlmm_test_silent_falling", the GPIO is switched
to high state. The rising interrupt gets latched.
(b) The GPIO is re-configured for IRQF_TRIGGER_FALLING, but the latched
interrupt isn't cleared.
(c) The IRQ handler is called for the latched interrupt, but there
wasn't any falling edge.
3. (a) For "tlmm_test_silent_low", the GPIO remains in high state.
(b) The GPIO is re-configured for IRQF_TRIGGER_LOW. This seems to
result in a phantom interrupt that gets latched.
(c) The IRQ handler is called for the latched interrupt, but the GPIO
isn't in low state.
4. (a) For "tlmm_test_silent_high", the GPIO is switched to low state.
(b) This doesn't result in a latched interrupt, because RAW_STATUS_EN
was cleared when masking the level-triggered interrupt.
Fix this by clearing the interrupt state whenever making any changes to the
interrupt configuration. This includes previously disabled interrupts, but
also any changes to interrupt polarity or detection type.
With this change, all 16 test cases are now passing for the non-wakeup
GPIOs in the TLMM.

Tegra devices have an 'sfsel' bit field that determines whether a pin
operates in SFIO (Special Function I/O) or GPIO mode. Currently,
tegra_pinctrl_gpio_disable_free() sets this bit when releasing a GPIO.
However, tegra_pinctrl_set_mux() can be called independently in certain
code paths where gpio_disable_free() is not invoked. In such cases, failing
to set the SFIO mode could lead to incorrect pin configurations, resulting
in functional issues for peripherals relying on SFIO.
This patch ensures that whenever set_mux() is called, the SFIO mode is
correctly set in the Mux Register if the 'sfsel' bit is present. This
prevents situations where the pin remains in GPIO mode despite being
configured for SFIO use.
