Client drivers might want a copy of the crashlog to stash into a
devcoredump blob. Since device memory management can be very variable,
the actual devcoredump implementation is left to client drivers. Pass
the raw crashlog buffer to the client callback so it can use it if
desired.

When a process reduces its number of threads or clears bits in its CPU
affinity mask, the mm_cid allocation should eventually converge towards
smaller values.
However, the change introduced by:
commit 7e019dcc470f ("sched: Improve cache locality of RSEQ concurrency
IDs for intermittent workloads")
adds a per-mm/CPU recent_cid which is never unset unless a thread
migrates.
This is a tradeoff between:
A) Preserving cache locality after a transition from many threads to few
threads, or after reducing the hamming weight of the allowed CPU mask.
B) Making the mm_cid upper bounds wrt nr threads and allowed CPU mask
easy to document and understand.
C) Allowing applications to eventually react to mm_cid compaction after
reduction of the nr threads or allowed CPU mask, making the tracking
of mm_cid compaction easier by shrinking it back towards 0 or not.
D) Making sure applications that periodically reduce and then increase
again the nr threads or allowed CPU mask still benefit from good
cache locality with mm_cid.
Introduce the following changes:
* After shrinking the number of threads or reducing the number of
allowed CPUs, reduce the value of max_nr_cid so expansion of CID
allocation will preserve cache locality if the number of threads or
allowed CPUs increase again.
* Only re-use a recent_cid if it is within the max_nr_cid upper bound,
else find the first available CID.

Allows struct_ops programs to acqurie referenced kptrs from arguments
by directly reading the argument.
The verifier will acquire a reference for struct_ops a argument tagged
with "__ref" in the stub function in the beginning of the main program.
The user will be able to access the referenced kptr directly by reading
the context as long as it has not been released by the program.
This new mechanism to acquire referenced kptr (compared to the existing
"kfunc with KF_ACQUIRE") is introduced for ergonomic and semantic reasons.
In the first use case, Qdisc_ops, an skb is passed to .enqueue in the
first argument. This mechanism provides a natural way for users to get a
referenced kptr in the .enqueue struct_ops programs and makes sure that a
qdisc will always enqueue or drop the skb.

Currently, ctx_arg_info is read-only in the view of the verifier since
it is shared among programs of the same attach type. Make each program
have their own copy of ctx_arg_info so that we can use it to store
program specific information.
In the next patch where we support acquiring a referenced kptr through a
struct_ops argument tagged with "__ref", ctx_arg_info->ref_obj_id will
be used to store the unique reference object id of the argument. This
avoids creating a requirement in the verifier that "__ref" tagged
arguments must be the first set of references acquired [0].

Tony Nguyen says:
====================
ice, iavf: Add support for Rx timestamping
Mateusz Polchlopek says:
Initially, during VF creation it registers the PTP clock in
the system and negotiates with PF it's capabilities. In the
meantime the PF enables the Flexible Descriptor for VF.
Only this type of descriptor allows to receive Rx timestamps.
Enabling virtual clock would be possible, though it would probably
perform poorly due to the lack of direct time access.
Enable timestamping should be done using userspace tools, e.g.
hwstamp_ctl -i $VF -r 14
In order to report the timestamps to userspace, the VF extends
timestamp to 40b.
To support this feature the flexible descriptors and PTP part
in iavf driver have been introduced.

Pull vfs fixes from Christian Brauner:
"It was reported that the acct(2) system call can be used to trigger a
NULL deref in cases where it is set to write to a file that triggers
an internal lookup.
This can e.g., happen when pointing acct(2) to /sys/power/resume. At
the point the where the write to this file happens the calling task
has already exited and called exit_fs() but an internal lookup might
be triggered through lookup_bdev(). This may trigger a NULL-deref when
accessing current->fs.
Reorganize the code so that the the final write happens from the
workqueue but with the caller's credentials. This preserves the
(strange) permission model and has almost no regression risk.
Also block access to kernel internal filesystems as well as procfs and
sysfs in the first place.
Various fixes for netfslib:
- Fix a number of read-retry hangs, including:
- Incorrect getting/putting of references on subreqs as we retry
them
- Failure to track whether a last old subrequest in a retried set
is superfluous
- Inconsistency in the usage of wait queues used for subrequests
(ie. using clear_and_wake_up_bit() whilst waiting on a private
waitqueue)
- Add stats counters for retries and publish in /proc/fs/netfs/stats.
This is not a fix per se, but is useful in debugging and shouldn't
otherwise change the operation of the code
- Fix the ordering of queuing subrequests with respect to setting the
request flag that says we've now queued them all"

Both the FF-A core and the bus were in a single module before the
commit 18c250bd7ed0 ("firmware: arm_ffa: Split bus and driver into distinct modules").
The arm_ffa_bus_exit() takes care of unregistering all the FF-A devices.
Now that there are 2 distinct modules, if the core driver is unloaded and
reloaded, it will end up adding duplicate FF-A devices as the previously
registered devices weren't unregistered when we cleaned up the modules.
Fix the same by unregistering all the FF-A devices on the FF-A bus during
the cleaning up of the partitions and hence the cleanup of the module.

Initial thought was to do something similar to __cond_lock()
do_iio_device_claim_direct_mode(iio_dev) ? : ({ __acquire(iio_dev); 0; })
+ Appropriate static inline iio_device_release_direct_mode()
However with that, sparse generates false positives. E.g.
drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_core.c:1811:17: warning: context imbalance in 'st_lsm6dsx_read_raw' - unexpected unlock
So instead, this patch rethinks the return type and makes it more
'conditional lock like' (which is part of what is going on under the hood
anyway) and return a boolean - true for successfully acquired, false for
did not acquire.
To allow a migration path given the rework is now non trivial, take a leaf
out of the naming of the conditional guard we currently have for IIO
device direct mode and drop the _mode postfix from the new functions giving
iio_device_claim_direct() and iio_device_release_direct()
Whilst the kernel supports __cond_acquires() upstream sparse does not
yet do so. Hence rely on sparse expanding a static inline wrapper
to explicitly see whether __acquire() is called.
Note that even with the solution here, sparse sometimes gives false
positives. However in the few cases seen they were complex code
structures that benefited from simplification anyway.

Add a new object called an interface queue (ifq) that represents a net
rx queue that has been configured for zero copy. Each ifq is registered
using a new registration opcode IORING_REGISTER_ZCRX_IFQ.
The refill queue is allocated by the kernel and mapped by userspace
using a new offset IORING_OFF_RQ_RING, in a similar fashion to the main
SQ/CQ. It is used by userspace to return buffers that it is done with,
which will then be re-used by the netdev again.
The main CQ ring is used to notify userspace of received data by using
the upper 16 bytes of a big CQE as a new struct io_uring_zcrx_cqe. Each
entry contains the offset + len to the data.
For now, each io_uring instance only has a single ifq.

only field of io_tw_state but kept it as a task work callback argument
to "forc[e] users not to invoke them carelessly out of a wrong context".
Passing the struct io_tw_state * argument adds a few instructions to all
callers that can't inline the functions and see the argument is unused.
So pass struct io_tw_state by value instead. Since it's a 0-sized value,
it can be passed without any instructions needed to initialize it.

In preparation for changing how io_tw_state is passed, introduce a type
alias io_tw_token_t for struct io_tw_state *. This allows for changing
the representation in one place, without having to update the many
functions that just forward their struct io_tw_state * argument.
Also add a comment to struct io_tw_state to explain its purpose.

Remove all struct io_buffer caches. It makes it a fair bit simpler.
Apart from from killing a bunch of lines and juggling between lists,
__io_put_kbuf_list() doesn't need ->completion_lock locking now.

Pull driver core api addition from Greg KH:
"Here is a driver core new api for 6.14-rc3 that is being added to
allow platform devices from stop being abused.
It adds a new 'faux_device' structure and bus and api to allow almost
a straight or simpler conversion from platform devices that were not
really a platform device. It also comes with a binding for rust, with
an example driver in rust showing how it's used.
I'm adding this now so that the patches that convert the different
drivers and subsystems can all start flowing into linux-next now
through their different development trees, in time for 6.15-rc1.
We have a number that are already reviewed and tested, but adding
those conversions now doesn't seem right. For now, no one is using
this, and it passes all build tests from 0-day and linux-next, so all
should be good"

Pull kvm fixes from Paolo Bonzini:
"ARM:
- Large set of fixes for vector handling, especially in the
interactions between host and guest state.
This fixes a number of bugs affecting actual deployments, and
greatly simplifies the FP/SIMD/SVE handling. Thanks to Mark Rutland
for dealing with this thankless task.
- Fix an ugly race between vcpu and vgic creation/init, resulting in
unexpected behaviours
- Fix use of kernel VAs at EL2 when emulating timers with nVHE
- Small set of pKVM improvements and cleanups
x86:
- Fix broken SNP support with KVM module built-in, ensuring the PSP
module is initialized before KVM even when the module
infrastructure cannot be used to order initcalls
- Reject Hyper-V SEND_IPI hypercalls if the local APIC isn't being
emulated by KVM to fix a NULL pointer dereference
- Enter guest mode (L2) from KVM's perspective before initializing
the vCPU's nested NPT MMU so that the MMU is properly tagged for
L2, not L1
- Load the guest's DR6 outside of the innermost .vcpu_run() loop, as
the guest's value may be stale if a VM-Exit is handled in the
fastpath"

Introduce the new helper for_each_node_numadist() to iterate over node
IDs in order of increasing NUMA distance from a given starting node.
This iterator is somehow similar to for_each_numa_hop_mask(), but
instead of providing a cpumask at each iteration, it provides a node ID.
Example usage:
nodemask_t unvisited = NODE_MASK_ALL;
int node, start = cpu_to_node(smp_processor_id());
node = start;
for_each_node_numadist(node, unvisited)
pr_info("node (%d, %d) -> %d\n",
start, node, node_distance(start, node));
On a system with equidistant nodes:
$ numactl -H
...
node distances:
node 0 1 2 3
0: 10 20 20 20
1: 20 10 20 20
2: 20 20 10 20
3: 20 20 20 10
Output of the example above (on node 0):
[ 7.367022] node (0, 0) -> 10
[ 7.367151] node (0, 1) -> 20
[ 7.367186] node (0, 2) -> 20
[ 7.367247] node (0, 3) -> 20
On a system with non-equidistant nodes (simulated using virtme-ng):
$ numactl -H
...
node distances:
node 0 1 2 3
0: 10 51 31 41
1: 51 10 21 61
2: 31 21 10 11
3: 41 61 11 10
Output of the example above (on node 0):
[ 8.953644] node (0, 0) -> 10
[ 8.953712] node (0, 2) -> 31
[ 8.953764] node (0, 3) -> 41
[ 8.953817] node (0, 1) -> 51

Nodemasks now pull linux/numa.h for MAX_NUMNODES and NUMA_NO_NODE
macros. This series makes numa.h depending on nodemasks, so we hit
a circular dependency.
Nodemasks library is highly employed by NUMA code, and it would be
logical to resolve the circular dependency by making NUMA headers
dependent nodemask.h.
