The per-error decode in tegra30_mc_handle_irq() dereferences
mc->soc->regs unconditionally. This 'regs' structure is optional and is
only used for decoding and logging MC error interrupts. The rest of the
MC functionality does not depend on it.
When adding support for the Tegra238 SoC, the 'regs' structure was
initially omitted because it is only used for error logging. We found
that this resulted in a NULL pointer dereference in IRQ context, causing
a crash when an MC error interrupt fired. Although existing upstream
devices will not hit this condition because 'regs' is present, guard
against it to improve the robustness of the driver.
Skip the decode and just clear the interrupt when mc_regs is NULL. This
bypasses the error interrupt logging while keeping the remaining MC
functionality intact.

Add support for representing each memory-controller instance (one
per NUMA node / socket) as its own interconnect (ICC) provider,
with its own MC client nodes, to match the hardware topology on
multi-socket Tegra SoCs.
Use the NUMA node ID to make client IDs globally unique across
per-socket providers, since the ICC framework allocates node IDs
from a single global IDR. Per-socket MC and EMC node names are
also derived from dev_name() so they match the corresponding
debugfs subdirectory. On single-socket platforms (NUMA_NO_NODE)
the existing client IDs and node-name strings are preserved.
Each socket's MC and EMC therefore get their own debugfs
subdirectory under /sys/kernel/debug/{mc,emc}/. The parent
directories are created on first probe.
Bandwidth requests from MC clients in a socket are routed to
that socket's local BPMP.

ipu7_resume() calls pm_runtime_get_sync() before resuming the device.
If the runtime PM resume fails, the usage count remains incremented, but
the error path returns without dropping the reference.
Use pm_runtime_resume_and_get() instead, which balances the usage count
on failure and avoids the leak. Keep returning 0 on error, as resume
callbacks should not propagate failures to the PM core, matching the
behaviour of the ipu6 driver.

snd_ctl_open() unconditionally overwrites the return value of
snd_card_file_add() with -ENODEV on failure, discarding the actual
error code.
Fix this by directly returning the original error code returned by
snd_card_file_add() (e.g. -ENOMEM or -ENODEV). This behavior is
consistent with the error handling used in other functions such as
snd_mixer_oss_open(), snd_hwdep_open(), snd_pcm_oss_open(), and others.
There is no functional change other than the returned error code in this
failure path.

The device with USB ID 040b:0897 (Weltrend Semiconductor chipset,
sold rebranded as the Redragon H510-PRO Wireless headset, reporting
"XiiSound Technology Corporation" in its USB string descriptors)
reports a constant value on GET_CUR for its PCM Playback Volume
control while still supporting an actually tunable volume. This
trips the sticky-value detection in check_sticky_volume_control(),
which disables the mixer control entirely:
usb 1-4: 5:0: sticky mixer values (0/100/1 => 80), disabling
As a result, the device boots with playback volume effectively muted
and provides no way to raise it through the normal ALSA/PipeWire
mixer path.
Apply QUIRK_FLAG_MIXER_GET_CUR_BROKEN so the sticky check marks the
control as get_cur_broken and relies on the cached value instead of
disabling the mixer control outright.
Tested by backporting this quirk flag and the supporting
get_cur_broken logic onto a Linux 7.1.2-zen kernel build that does
not yet carry it, and confirming that after applying the flag the
kernel log changes from
usb 1-4: 5:0: sticky mixer values (0/100/1 => 80), disabling
to
usb 1-4: 5:0: broken mixer GET_CUR (0/100/1 => 80)
with the control usable via the driver's cached value afterward.

Branch Sampling (BRS) and Last Branch Record (LBR) are mutually
exclusive hardware features, and users of both are tracked via
cpuc->lbr_users.
When SVM is toggled on a CPU, the host perf events are reprogrammed to
update the HostOnly filter bit (set when virtualization is enabled,
cleared when it is disabled). On PerfMonV2-capable processors, this
reprogramming is performed by calling amd_pmu_enable_all() to rewrite
the event selectors. However, amd_pmu_enable_all() also calls
amd_brs_enable_all(), which enables BRS whenever cpuc->lbr_users > 0.
Having active LBR events satisfies this gating on processors that have
LBR but not BRS. The kernel then tries to set the BRS enable bit in
DebugExtnCfg (MSR 0xc000010f). Since that bit is deprecated on such
hardware, the write results in a #GP:

====================
selftests: drv-net: run XDP tests with both IP versions
The driver selftest environment picks a single address family for tests
which use the generic address fields. When both IPv4 and IPv6 are
available it prefers IPv6, which can leave IPv4 paths untested and hide
IPv4-only bugs.
This happened recently in the XDP selftest, where an IPv4 checksum bug
was missed when IPv6 was also configured. XDP traffic handling has
IP-version-specific code paths, and the follow-up discussion concluded
that the XDP tests should run against both IP versions [1].
This series changes NetDrvEpEnv from exposing only the initially selected
address family to allowing tests to switch the generic address fields
between IP versions. xdp.py uses this to run the XDP traffic cases over
both IPv4 and IPv6. Test variants whose required IP version is not
configured are skipped.

The snd-aloop driver currently defaults to using the system jiffies
timer (struct timer_list). On systems configured with a low timer
interrupt frequency (e.g., CONFIG_HZ=250), the jiffies resolution
(4ms per tick) is insufficient for precise audio timing. For
example, a 10ms audio period requires 2.5 jiffies ticks, causing
timing jitter that leads to capture underruns.
Introduce "hrtimer" as a supported timer_source option. When
timer_source="hrtimer" is set, aloop uses high-resolution timers
(hrtimer) to drive period updates. This provides nanosecond-level
accuracy regardless of CONFIG_HZ and operates independently of other
hardware audio cards.

CAKE accepts signed overhead values and stores them in an s16, but the
adjusted packet length calculation uses unsigned arithmetic. A negative
effective length can therefore wrap to a large value.
Such configurations make rate accounting depend on integer wraparound
rather than on the packet size userspace intended to model. A static
netlink lower bound is not enough because packets reaching CAKE can be
smaller than any reasonable manual-overhead allowance.
Fold the signed overhead adjustment into the existing datapath MPU clamp
so negative adjusted lengths are clamped before link-layer framing
adjustments.

'devlink-extend-phys_port_name-controller-prefix-to-non-external-ports'
Tariq Toukan says:
====================
devlink: extend phys_port_name controller prefix to non-external ports
This series by Moshe includes the controller number in phys_port_name
for non-external ports with a non-zero controller, and updates the mlx5
driver to mark satellite PFs as non-external.
The controller prefix (c) in phys_port_name was previously only included
for ports marked as external. However, newer devices can have multiple
controllers within the DPU itself, even within a single host
environment. For example, a SmartNIC may have additional local PCI
physical functions that are managed by the eswitch but are not on an
external host. These ports use a non-zero controller number to
distinguish them from the eswitch manager's own functions, while the
external flag remains unset.
Patch 1 updates the devlink core to include the controller prefix in
phys_port_name for any non-zero controller, regardless of the external
flag. Documentation and kdoc are updated accordingly.
Patch 2 updates the mlx5 driver to set satellite PF devlink ports as
non-external, since they are local to the DPU. It also distinguishes
satellite PF SFs from host PF SFs when setting the external attribute.

Satellite PFs are local to the DPU and are not on an external host.
Set their devlink port external attribute to false to reflect this.
For satellite PF SFs, distinguish them from host PF SFs by comparing
the SF controller number against the host PF controller
(hpf_host_number + 1). Only SFs whose controller matches the host PF
are marked external, since their PF resides on an external host.

The controller prefix (c<N>) in phys_port_name is currently restricted
to external host controllers. This layout sufficed when DPUs only had a
single local controller and one or more external host controllers.
However, newer devices can have multiple controllers within the DPU
itself, even within a single host environment. To support these
topologies, allow drivers to report the controller number regardless of
the "external" flag status. Any non-zero controller number will now be
explicitly reported, even for single-host or local DPU controllers.
Existing ports with controller=0 are unaffected.
Update documentation and kdoc to clarify that a non-zero controller
number does not require the external flag to be set.

When fuse enables large folios, a large folio will be backed by
iomap_folio_state that keeps track of uptodate and dirty state in an
internal bitmap.
Fuse writethrough and notify store paths currently set folio uptodate
state with folio_mark_uptodate(), which touches only the folio-level
flag, but on an iomap-backed folio, that leaves the uptodate bitmap out
of sync.
Use the iomap_folio_mark_uptodate() helper to update both the folio
uptodate state and the iomap uptodate bitmap.

Add an exported helper iomap_folio_mark_uptodate() to mark a folio as
uptodate and update its uptodate bitmap if the folio has iomap state
data attached.
This is needed because there are some filesystems (eg fuse) that have
paths outside of conventional iomap calls that need to mark a folio as
uptodate (eg writing server-pushed data directly into the page cache)
and need the iomap-internal uptodate bitmap to be in sync with the
uptodate state of the folio.

In the writethrough path (fuse_send_write_pages()), if the write to the
server failed or was a short write, the uptodate flag on the folios are
cleared.
As explained by Matthew in [1], this is dangerous because the folio may
be mapped into userspace. The mm code has the invariant that a
non-uptodate folio must never be visible to userspace (to avoid
potentially leaking confidental information to userspace) and has checks
in place for this that if violated can bring down the whole machine.
Practically speaking, the effect of this change for the fuse
writethrough error path is that if an application does a write and then
the server fails to persist the data or only services a short write, the
page cache folio keeps the data the application wrote instead of being
reverted to the server's contents on the next read. The failure is still
reported to the application synchronously through the short count /
error return of the write() syscall. Folios that were only partially
written are unaffected since they were never marked uptodate in the
first place (fuse_fill_write_page() only marks a folio as uptodate if
the whole folio was written to).

net: dsa: microchip: move non-common function out of ksz_common.c
This series continues the rework of the KSZ driver initiated by three
previous series (see [1], [2] & [3]).
The KSZ driver handles more than 20 switches split in several families.
This was previously handled through a common set of dsa_switch_ops
operations that used device-specific ksz_dev_ops callbacks. The three
previous series have split this common struct dsa_switch_ops into 5
to connect the ksz_dev_ops's implentations directly to the new
dsa_swicth ops.
This series continues in the same vein and moves out of ksz_common.c all
the functions that aren't truly common to all the families.
On top of this on-going rework I added PTP and periodic output support for
the KSZ8463 (which was my first goal). There are still more than 13 patches
left for all this so this series will be followed by two others and if you
want to see the full picture we can check my github ([4]).
FYI, I only have a KSZ8463 so, unfortunately, I can't test other switches.
The next series is going to add PTP support for the KSZ8463. The final one
will add periodic output support for the KSZ8463.

The drive strength configuration is done during the setup of all
switches through a common function that then has specific behavior
depending on the switch identity.
Split the common configuration in two functions: one is dedicated to the
KSZ8 family, the other is dedicated to the KSZ9477 family.
Remove the drive strength configuration from the lan937x_setup since
the LAN937x family doesn't support it.

The setup of QDISC_ETS isn't the same for the KSZ8 switches than for
the other switches. It leads to is_ksz8() branches in the common code.
Move the KSZ8-specific portions into ksz8.c by creating two setup_tc()
functions, one dedicated to the KSZ87xx family that only handles the
TC_SETUP_QDISC_CBS case, one for the rest of the KSZ8 that handles both
TC_SETUP_QDISC_CBS and TC_SETUP_QDISC_ETS cases.
It remains some is_kszXXXX() branches because inside the ksz88xx family,
only the ksz88x3 switches support QDISC_ETS.
