The bit index of the peripheral clock for mmc A is wrong
This was probably not a problem for mmc A as the peripheral is likely left
enabled by the bootloader.
No issues has been reported so far but it could be a problem, most likely
some form of conflict between the ethernet and mmc A clock, breaking
ethernet on init.
Use the value provided by the documentation for mmc A before this
becomes an actual problem.

On powerpc, a CPU does not necessarily originate from NUMA node 0.
This contrasts with architectures like x86, where CPU 0 is not
hot-pluggable, making NUMA node 0 a consistently valid node.
This discrepancy can lead to failures when creating a map on NUMA
node 0, which is initialized by default, if no CPUs are allocated
from NUMA node 0.
This patch fixes the issue by setting NUMA_NO_NODE (-1) for map
creation for this selftest.

that this clock should be provided by AO controller.
The HW probably has this clock but it does not exist at the moment in

Several clocks used by both g12a and g12b use the g12a cpu A clock hw
pointer as clock parent. This is incorrect on g12b since the parents of
cluster A cpu clock are different. Also the hw clock provided as parent to
these children is not even registered clock on g12b.
Fix the problem by reverting to the global namespace and let CCF pick
the appropriate, as it is already done for other clocks, such as

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.

The ib_post_receive_mads() function handles posting receive work
requests (WRs) to MAD QPs and is called in two cases:
1) When a MAD port is opened.
2) When a receive WQE is consumed upon receiving a new MAD.
Whereas, if MADs arrive during the port open phase, a race condition
might cause an extra WR to be posted, exceeding the QP’s capacity.
This leads to failures such as:
infiniband mlx5_0: ib_post_recv failed: -12
infiniband mlx5_0: Couldn't post receive WRs
infiniband mlx5_0: Couldn't start port
infiniband mlx5_0: Couldn't open port 1
Fix this by checking the current receive count before posting a new WR.
If the QP’s receive queue is full, do not post additional WRs.

Previously, the invalidation counter was incorrectly updated for the

The problem can be reproduced using the following steps:
ip netns add foo
ip netns exec foo bash
cat /sys/class/infiniband/mlx4_0/hw_counters/*
The panic occurs because of casting the device pointer into an
ib_device pointer using container_of() in hw_stat_device_show() is
wrong and leads to a memory corruption.
However the real problem is that hw counters should never been exposed
outside of the non-init net namespace.
Fix this by saving the index of the corresponding attribute group
(it might be 1 or 2 depending on the presence of driver-specific
attributes) and zeroing the pointer to hw_counters group for compat
devices during the initialization.
With this fix applied hw_counters are not available in a non-init
net namespace:
find /sys/class/infiniband/mlx4_0/ -name hw_counters
/sys/class/infiniband/mlx4_0/ports/1/hw_counters
/sys/class/infiniband/mlx4_0/ports/2/hw_counters

bpf_send_signal_common() uses preemptible() to check whether or not the
current context is preemptible. If it is preemptible, it will use
irq_work to send the signal asynchronously instead of trying to hold a
spin-lock, because spin-lock is sleepable under PREEMPT_RT.
However, preemptible() depends on CONFIG_PREEMPT_COUNT. When
CONFIG_PREEMPT_COUNT is turned off (e.g., CONFIG_PREEMPT_VOLUNTARY=y),
!preemptible() will be evaluated as 1 and bpf_send_signal_common() will
use irq_work unconditionally.
Fix it by unfolding "!preemptible()" and using "preempt_count() != 0 ||

The strncmp benchmark uses the bpf_strncmp helper and a hand-written
loop to compare two strings. The values of the strings are filled from
userspace. One of the strings is non-const (in .bss) while the other is
const (in .rodata) since that is the requirement of bpf_strncmp.
The problem is that in the hand-written loop, Clang optimizes the reads
from the const string to always return 0 which breaks the benchmark.
Use barrier_var to prevent the optimization.
The effect can be seen on the strncmp-no-helper variant.

There is case as below could trigger kernel dump:
Use U-Boot to start remote processor(rproc) with resource table
published to a fixed address by rproc. After Kernel boots up,
stop the rproc, load a new firmware which doesn't have resource table
,and start rproc.
When starting rproc with a firmware not have resource table,
`memcpy(loaded_table, rproc->cached_table, rproc->table_sz)` will
trigger dump, because rproc->cache_table is set to NULL during the last
stop operation, but rproc->table_sz is still valid.
This issue is found on i.MX8MP and i.MX9.

mdacon has roughly the same dependencies as vgacon but expresses them
as a negative list instead of a positive list, with the only practical
difference being PowerPC/CHRP, which uses vga16fb instead of vgacon.
The CONFIG_MDA_CONSOLE description advises to only turn it on when vgacon
is also used because MDA/Hercules-only systems should be using vgacon
instead, so just change the list to enforce that directly for simplicity.
The probing was broken from 2002 to 2008, this improves on the fix
that was added then: If vgacon is a loadable module, then mdacon
cannot be built-in now, and the list of systems that support vgacon
is carried over.

There is a type mismatch between what CalculateDynamicMetadataParameters()
takes and what is passed to it. Currently this function accepts several
args as signed long but it's called with unsigned integers and integer. On
some systems where long is 32 bits and one of these unsigned int params is
greater than INT_MAX it may cause passing input params as negative values.
Fix this by changing these argument types from long to unsigned int and to
int respectively. Also this will align the function's definition with
similar functions in other dcn* drivers.

After d88f521da3 ("PCI: Allow userspace to query and set device reset
mechanism"), userspace can disable reset of specific PCI devices by writing
an empty string to the sysfs reset_method file.
However, pci_slot_resettable() does not check pci_reset_supported(), which
means that pci_reset_function() will still reset the device even if
userspace has disabled all the reset methods.
I was able to reproduce this issue with a vfio device passed to a qemu
guest, where I had disabled PCI reset via sysfs.
Add an explicit check of pci_reset_supported() in both
pci_slot_resettable() and pci_bus_resettable() to ensure both the reset
status and reset execution are bypassed if an administrator disables it for
a device.

Firmware developers reported that Linux issues two PCIe hotplug commands in
very short intervals on an ARM server, which doesn't comply with the PCIe
spec. According to PCIe r6.1, sec 6.7.3.2, if the Command Completed event
is supported, software must wait for a command to complete or wait at
least 1 second before sending a new command.
In the failure case, the first PCIe hotplug command is from
get_port_device_capability(), which sends a command to disable PCIe hotplug
interrupts without waiting for its completion, and the second command comes
from pcie_enable_notification() of pciehp driver, which enables hotplug
interrupts again.
Fix this by only disabling the hotplug interrupts when the pciehp driver is
not enabled.

Ordering issues here cause an uninitialized (default STANDALONE)
usecase to be programmed (which appears to be a MUX) in some cases
when msm_dsi_host_register() is called, leading to the slave PLL in
bonded-DSI mode to source from a clock parent (dsi1vco) that is off.
This should seemingly not be a problem as the actual dispcc clocks from
DSI1 that are muxed in the clock tree of DSI0 are way further down, this
bit still seems to have an effect on them somehow and causes the right
side of the panel controlled by DSI1 to not function.
In an ideal world this code is refactored to no longer have such
error-prone calls "across subsystems", and instead model the "PLL src"
register field as a regular mux so that changing the clock parents
programmatically or in DTS via `assigned-clock-parents` has the
desired effect.
But for the avid reader, the clocks that we *are* muxing into DSI0's
tree are way further down, so if this bit turns out to be a simple mux
between dsiXvco and out_div, that shouldn't have any effect as this
whole tree is off anyway.

Before 456d8aa37d ("PCI/ASPM: Disable ASPM on MFD function removal to
avoid use-after-free"), we would free the ASPM link only after the last
function on the bus pertaining to the given link was removed.
That was too late. If function 0 is removed before sibling function,
link->downstream would point to free'd memory after.
After above change, we freed the ASPM parent link state upon any function
removal on the bus pertaining to a given link.
That is too early. If the link is to a PCIe switch with MFD on the upstream
port, then removing functions other than 0 first would free a link which
still remains parent_link to the remaining downstream ports.
The resulting GPFs are especially frequent during hot-unplug, because
pciehp removes devices on the link bus in reverse order.
On that switch, function 0 is the virtual P2P bridge to the internal bus.
Free exactly when function 0 is removed -- before the parent link is
obsolete, but after all subordinate links are gone.

We can see that the window to 0006:03 gets shrunken too much and 0006:04
eats away the window for 0006:03:00.2.
The offending commit distributes the upstream bridge's resources multiple
times to every downstream bridge, hence makes the aperture smaller than
desired because calculation of io_per_b, mmio_per_b and mmio_pref_per_b
becomes incorrect.
Instead, distribute downstream bridges' own resources to resolve the issue.

Fix a typo where V compare incorrectly compares av[] with av[] itself,
which can result in HDCP failure.
The loop of V compare is expected to iterate for 5 times
which compare V array form av[0][] to av[4][].
It should check loop counter reach the last statement "i == 5"
before return true

[ Upstream commit 6bbce873a9c97cb12f5455c497be279ac58e707f ]
[Why]
The RAD of sideband message printed today is incorrect.
For RAD stored within MST branch
- If MST branch LCT is 1, it's RAD array is untouched and remained as 0.
- If MST branch LCT is larger than 1, use nibble to store the up facing
port number in cascaded sequence as illustrated below:
u8 RAD[0] = (LCT_2_UFP << 4) | LCT_3_UFP
RAD[1] = (LCT_4_UFP << 4) | LCT_5_UFP
...
In drm_dp_mst_rad_to_str(), it wrongly to use BIT_MASK(4) to fetch the port
number of one nibble.
[How]
Adjust the code by:
- RAD array items are valuable only for LCT >= 1.
- Use 0xF as the mask to replace BIT_MASK(4)
V2:
- Document how RAD is constructed (Imre)
V3:
- Adjust the comment for rad[] so kdoc formats it properly (Lyude)

[ Upstream commit 574f5ee2c85a00a579549d50e9fc9c6c072ee4c4 ]
Each bridge instance creates up to four auxiliary devices with different
names. However, their IDs are always zero, causing duplicate filename
errors when a system has multiple bridges:
sysfs: cannot create duplicate filename '/bus/auxiliary/devices/ti_sn65dsi86.gpio.0'
Fix this by using a unique instance ID per bridge instance. The
instance ID is derived from the I2C adapter number and the bridge's I2C
address, to support multiple instances on the same bus.

[ Upstream commit 45ff65e30deb919604e68faed156ad96ce7474d9 ]
For 'ti,j7200-cpb-audio' compatible, there is support for only one PLL for
48k. For 11025, 22050, 44100 and 88200 sampling rates, due to absence of
J721E_CLK_PARENT_44100, we get EINVAL while running any audio application.
Add support for these rates by using the 48k parent clock and adjusting
the clock for these rates later in j721e_configure_refclk.
