====================
Add support for mdb offload failure notification
Currently the bridge does not provide real-time feedback to user space
on whether or not an attempt to offload an mdb entry was successful.
This patch set adds support to notify user space about failed offload
attempts, and is controlled by a new knob mdb_offload_fail_notification.
A break-down of the patches in the series:
Patch 1 adds offload failed flag to indicate that the offload attempt
has failed. The flag is reflected in netlink mdb entry flags.
Patch 2 adds the new bridge bool option mdb_offload_fail_notification.
Patch 3 notifies user space when the result is known, controlled by
mdb_offload_fail_notification setting.

netdevice reg_state was split into two 16 bit enums back in 2010
in commit a2835763e1 ("rtnetlink: handle rtnl_link netlink
notifications manually"). Since the split the fields have been
moved apart, and last year we converted reg_state to a normal
u8 in commit 4d42b37def ("net: convert dev->reg_state to u8").
rtnl_link_state being a 16 bitfield makes no sense. Convert it
to a single bool, it seems very unlikely after 15 years that
we'll need more values in it.
We could drop dev->rtnl_link_ops from the conditions but feels
like having it there more clearly points at the reason for this
hack.

We started generating C code for OvS a while back, but actually
C codegen only supports fixed headers specified at the family
level right now (schema also allows specifying them per op).
ovs_flow and ovs_datapath already specify the fixed header
at the family level but ovs_vport does it per op.
Move the property, all ops use the same header.
This ensures YNL C sees the correct hdr_len:
const struct ynl_family ynl_ovs_vport_family = {
.name = "ovs_vport",
- .hdr_len = sizeof(struct genlmsghdr),
+ .hdr_len = sizeof(struct genlmsghdr) + sizeof(struct ovs_header),

Lockdep found the following dependency:
&dev_instance_lock_key#3 -->
&rdev->wiphy.mtx -->
&net->xdp.lock -->
&xs->mutex -->
&dev_instance_lock_key#3
The first dependency is the problem. wiphy mutex should be outside
the instance locks. The problem happens in notifiers (as always)
for CLOSE. We only hold the instance lock for ops locked devices
during CLOSE, and WiFi netdevs are not ops locked. Unfortunately,
when we dev_close_many() during netns dismantle we may be holding
the instance lock of _another_ netdev when issuing a CLOSE for
a WiFi device.
Lockdep's "Possible unsafe locking scenario" only prints 3 locks
and we have 4, plus I think we'd need 3 CPUs, like this:
CPU0 CPU1 CPU2
---- ---- ----
lock(&xs->mutex);
lock(&dev_instance_lock_key#3);
lock(&rdev->wiphy.mtx);
lock(&net->xdp.lock);
lock(&xs->mutex);
lock(&rdev->wiphy.mtx);
lock(&dev_instance_lock_key#3);
Tho, I don't think that's possible as CPU1 and CPU2 would
be under rtnl_lock. Even if we have per-netns rtnl_lock and
wiphy can span network namespaces - CPU0 and CPU1 must be
in the same netns to see dev_instance_lock, so CPU0 can't
be installing a socket as CPU1 is tearing the netns down.
Regardless, our expected lock ordering is that wiphy lock
is taken before instance locks, so let's fix this.
Go over the ops locked and non-locked devices separately.
Note that calling dev_close_many() on an empty list is perfectly
fine. All processing (including RCU syncs) are conditional
on the list not being empty, already.

Move more display specific parts of GPU error logging behind the display
snapshot interface.
With the display register capture reduced to just one register, DERRMR,
there's quite a bit of boilerplate here. However, it's still a nice
abstraction and removes a DISPLAY_VER() usage from core i915. With this
approach, it's also easy to add to xe as needed.

Like SG2042, SG2044 also uses an external MSI controller to provide
MSI interrupt for PCIe controllers. The difference between these
two MSI controllers are:
1. SG2044 acks the interrupt by writing 0, SG2042 by setting the
bit related to the interrupt.
2. SG2044 uses interrupt number modulo 32 as MSI message data, but
SG2042 uses the bit related to the interrupt.

- Regression in RXE support foudn by blktests due to missing ODP
exclusions
- Set the dma_segment_size on HNS so it doesn't corrupt DMA when using
very large IOs
- Move a INIT_WORK to near when the work is allocated in cm.c to fix a
racey crash where work in progress was being init'd
- Use __GFP_NOWARN to not dump in kvcalloc() if userspace requests a
very big MR

RDMA/bnxt_re: Remove unusable nq variable
RDMA/core: Silence oversized kvmalloc() warning
RDMA/cma: Fix workqueue crash in cma_netevent_work_handler
RDMA/hns: Fix wrong maximum DMA segment size
RDMA/rxe: Fix null pointer dereference in ODP MR check
RDMA/mlx5: Fix compilation warning when USER_ACCESS isn't set
RDMA/usnic: Fix passing zero to PTR_ERR in usnic_ib_pci_probe()
RDMA/ucaps: Avoid format-security warning
RDMA/bnxt_re: Fix budget handling of notification queue
Modify the tools/sched_ext/Makefile to better handle cross-compilation
environments by:
1. Fix host tools build directory structure by separating obj/ from output
(HOST_BUILD_DIR now points to $(OBJ_DIR)/host/obj)
2. Properly propagate CROSS_COMPILE to libbpf sub-make invocation
3. Add missing $(HOST_BPFOBJ) build rule with proper host toolchain flags
(ARCH=, CROSS_COMPILE=, explicit HOSTCC/HOSTLD)
4. Consistently quote $(HOSTCC) in bpftool build rule
5. Change LDFLAGS assignment to += to allow external extensions
The changes ensure proper cross-compilation behavior while maintaining
backward compatibility with native builds. Host tools are now correctly
built with the host toolchain while target binaries use the cross-toolchain.

In commit d4563201f3 ("Documentation: simplify and clarify DCO
contribution example language"), the patch submission documentation was
updated to remove the note about pseudonyms and instead simplify it to
allow "known identities".
The process documentation still explicitly prohibits pseudonymous
contributors. This patch changes the process documentation to line up
with the submitting patches document.
