Accelerated Receive Flow Steering (aRFS) relies on sockets recording
their RX flow hash into the rps_sock_flow_table so that incoming packets
are steered to the CPU where the application runs.
With MPTCP, the application interacts with the parent MPTCP socket while
data is carried over per-subflow TCP sockets. Without recording these
subflows, aRFS cannot steer interrupts and RX processing for the flows
to the desired CPU.
Record all subflows in the RPS table by calling sock_rps_record_flow()
for each subflow at the start of mptcp_sendmsg(), mptcp_recvmsg() and
mptcp_stream_accept(), by using the new helper
mptcp_rps_record_subflows().
It does not by itself improve throughput, but ensures that IRQ and RX
processing are directed to the right CPU, which is a
prerequisite for effective aRFS.

Add a helper to check if RFS is needed or not. Allows to make the code a
bit cleaner and the next patch to have MPTCP use this helper to decide
whether or not to iterate over the subflows.
tun_flow_update() was calling sock_rps_record_flow_hash() regardless of
the state of rfs_needed. This was not really a bug as sock_flow_table
simply ends up being NULL and thus everything will be fine.
This commit here thus also implicitly makes tun_flow_update() respect
the state of rfs_needed.

Many scx schedulers make use of scx_bpf_cpu_rq() to check a remote curr

scx_bpf_cpu_rq() provides access to all fields of struct rq, most of
which aren't safe to use without holding the associated rq lock.

SCX hooks into CPU cgroup controller operations and read-locks
scx_cgroup_rwsem to exclude them while enabling and disable schedulers.
While this works, it's unnecessarily complicated given that
cgroup_[un]lock() are available and thus the cgroup operations can be locked
out that way.
Drop scx_cgroup_rwsem locking from the tg on/offline and cgroup [can_]attach
operations. Instead, grab cgroup_lock() from scx_cgroup_lock(). Drop
scx_cgroup_finish_attach() which is no longer necessary. Drop the now
unnecessary rcu locking and css ref bumping in scx_cgroup_init() and
scx_cgroup_exit().
As scx_cgroup_set_weight/bandwidth() paths aren't protected by
cgroup_lock(), rename scx_cgroup_rwsem to scx_cgroup_ops_rwsem and retain
the locking there.
This is overall simpler and will also allow enable/disable paths to
synchronize against cgroup changes independent of the CPU controller.

scx_enable() turns on the bypass mode while enable is in progress. If
enabling fails, it turns off the bypass mode and then triggers scx_error().
scx_error() will trigger scx_disable_workfn() which will turn on the bypass
mode again and unload the failed scheduler.
This moves the system out of bypass mode between the enable error path and
the disable path, which is unnecessary and can be brittle - e.g. the thread
running scx_enable() may already be on the failed scheduler and can be
switched out before it triggers scx_error() leading to a stall. The watchdog
would eventually kick in, so the situation isn't critical but is still
suboptimal.
There is nothing to be gained by turning off the bypass mode between
scx_enable() failure and scx_disable_workfn(). Keep bypass on.

During tasks iteration, the locks can be dropped using
scx_task_iter_unlock() to perform e.g. sleepable allocations. Afterwards,
scx_task_iter_relock() has to be called prior to other iteration operations,
which is error-prone. This can be easily automated by tracking whether
scx_tasks_lock is held in scx_task_iter and re-acquiring when necessary. It
already tracks whether the task's rq is locked after all.
- Add scx_task_iter->list_locked which remembers whether scx_tasks_lock is
held.
- Rename scx_task_iter->locked to scx_task_iter->locked_task to better
distinguish it from ->list_locked.
- Replace scx_task_iter_relock() with __scx_task_iter_maybe_relock() which
is automatically called by scx_task_iter_next() and scx_task_iter_stop().
- Drop explicit scx_task_iter_relock() calls.
The resulting behavior should be equivalent.

from the drm/sched teardown leak fix series:
https://lore.kernel.org/dri-devel/20250710125412.128476-2-phasta@kernel.org/
The aforementioned series removed a blocking waitqueue from
nouveau_sched_fini(). It was mistakenly assumed that this waitqueue only
prevents jobs from leaking, which the series fixed.
The waitqueue, however, also guarantees that all VM_BIND related jobs
are finished in order, cleaning up mappings in the GPU's MMU. These jobs
must be executed sequentially. Without the waitqueue, this is no longer
guaranteed, because entity and scheduler teardown can race with each
other.
Revert all patches related to the waitqueue removal.

Add the remaining clocks to the tree so as to be completed, which means
that the following RP1 peripherals could now consume their specific clocks
and be enabled to work (provided that the relevant driver changes for each
specific peripheral, if any, are committed):
- ADC
- Audio IN/OUT
- DMA controller
- I2S
- MIPI DPI/DSI
- PWM
- SDIO
- UART
- Video Encoder

Add missing address-cells 0 to GIC interrupt node to silence W=1
warning:
bcm2712.dtsi:494.4-497.31: Warning (interrupt_map): /axi/pcie@1000110000:interrupt-map:
Missing property '#address-cells' in node /soc@107c000000/interrupt-controller@7fff9000, using 0 as fallback
Value '0' is correct because:
1. GIC interrupt controller does not have children,
2. interrupt-map property (in PCI node) consists of five components and
the fourth component "parent unit address", which size is defined by
'#address-cells' of the node pointed to by the interrupt-parent
component, is not used (=0)

When a watch on dir=/ is combined with an fsnotify event for a
single-character name directly under / (e.g., creating /a), an
out-of-bounds read can occur in audit_compare_dname_path().
The helper parent_len() returns 1 for "/". In audit_compare_dname_path(),
when parentlen equals the full path length (1), the code sets p = path + 1
and pathlen = 1 - 1 = 0. The subsequent loop then dereferences
p[pathlen - 1] (i.e., p[-1]), causing an out-of-bounds read.
Fix this by adding a pathlen > 0 check to the while loop condition
to prevent the out-of-bounds access.

Fix incorrect argument order in devm_kcalloc() when allocating port->phys.
The original call used sizeof(phy) as the number of elements and
port->lanes as the element size, which is reversed. While this happens to
produce the correct total allocation size with current pointer size and
lane counts, the argument order is wrong.

(cherry picked from commit 1ee9d1a096)
Merge series from James Clark <james.clark@linaro.org>:
Improve usability of target mode by reporting FIFO errors and increasing
the buffer size when DMA is used. While we're touching DMA stuff also
switch to non-coherent memory, although this is unrelated to target
mode.
With the combination of the commit to increase the DMA buffer size and
the commit to use non-coherent memory, the host mode performance figures
are as follows on S32G3:
# spidev_test --device /dev/spidev1.0 --bpw 8 --size <test_size> --cpha --iter 10000000 --speed 10000000
Coherent (4096 byte transfers): 6534 kbps
Non-coherent: 7347 kbps
Coherent (16 byte transfers): 447 kbps
Non-coherent: 448 kbps
Just for comparison running the same test in XSPI mode:
4096 byte transfers: 2143 kbps
16 byte transfers: 637 kbps
These tests required hacking S32G3 to use DMA in host mode, although
the figures should be representative of target mode too where DMA is
used. And the other devices that use DMA in host mode should see similar
improvements.
match_var_offset() compares address offsets to determine if an access
falls within a variable's bounds. The offsets involved for those
relative to base registers from DW_OP_breg can be negative.
The current implementation uses unsigned types (u64) for these offsets,
which rejects almost all negative values.
Change the signature of match_var_offset() to use signed types (s64).
This ensures correct behavior when addr_offset or addr_type are
negative.

Commit 5806b3d051 ("cpuset: decouple tmpmasks and cpumasks freeing in
cgroup") separates out the freeing of tmpmasks into a new free_tmpmask()
helper but removes the NULL pointer check in the process. Unfortunately a
NULL pointer can be passed to free_tmpmasks() in cpuset_handle_hotplug()
if cpuset v1 is active. This can cause segmentation fault and crash
the kernel.
Fix that by adding the NULL pointer check to free_tmpmasks().

Fix sched_numa_find_nth_cpu() if mask offline
sched_numa_find_nth_cpu() uses a bsearch to look for the 'closest'
CPU in sched_domains_numa_masks and given cpus mask. However they
might not intersect if all CPUs in the cpus mask are offline. bsearch
will return NULL in that case, bail out instead of dereferencing a
bogus pointer.

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
This series is a direct follow up to the recent
machine-board-registration changes [1]. Initially, a number of smaller
patchsets were part of a bigger block of changes. My attempt to split
them up to make the review easier was unfortunately not successful [2].
The goal of this series is the same one as with [1] - allow for multiple
cards of the same type without workarounds or code duplications.
With the machine-board names being unique - thanks to
PLATFORM_DEVID_AUTO - platform component names shall be adjusted too so
that no misbindings happen.
In essence, majority of the changes can be summarized as: simplifying
card and dai_link initialization. Actions:
- drop mach->mach_params.platform usage
- drop snd_soc_fixup_dai_links_platform_name() usage
- for the probe-board mach-context is dropped entirely. The panic [2] is
gone
