"This includes a significant number of low-priority fixes - especially
in the NIC drivers area - that we deferred from the last few RCs in
the previous cycle, which can't be easily outlined in the synopsis
below.
Core & protocols:
- Continue the work on removing rtnl_lock dependencies:
- per-netns ARP and ND neighbour tables, with the default settings
now configurable per netns (inheritance from init_net is
controlled by the new net.core.neigh_inherit_init_net sysctl)
- RCU-protected configuration and rtnl_lock-less fill_info() for
hsr, netkit, sit, vlan and vxlan devices
- per-netns device unregistration for ip tunnel and gre devices
- use the netdev instance lock instead of rtnl_lock when reading
speed and duplex via sysfs

Pull sched_ext updates from Tejun Heo:
- Proxy execution can now be enabled together with sched_ext. A BPF
scheduler can opt in to receive mutex-blocked tasks that donate their
scheduling context to the lock owner and place them itself.
- Lazy preemption: a BPF scheduler can preempt or kick a CPU lazily,
deferring the switch to the next return to user space or tick, as the
fair class can.
- Sub-schedulers: a parent now learns which child runs on each CPU it
delegated and when a cap change takes effect. A detaching child loses
its caps before the parent restores the CPUs.
- New kfuncs re-enqueue single tasks from a dispatch queue iteration
and report a cgroup's CPU count and a CID's NUMA node. The CID
topology now includes clusters.

- A write to cgroup.subtree_control or cgroup.type could hang in D
state for as long as a task pinning a dying controller took to exit,
as syzbot reported. The wait is now interruptible.
- cpuset: the deadline bandwidth check ran on cpusets that weren't
valid partition roots, failing cpuset writes with -EBUSY while
deadline tasks existed. The CPU count the fair class takes from
cpuset assumed a shared hierarchy that cgroup1 may not have.
- Finding a cgroup's effective controller state no longer walks up the
hierarchy, for per-I/O users such as nvmet. io.stat reads of cgroups
without block devices skip the stat flush.
- cpuset v1-only code moved to the v1 file and the exclusive flag
dropped from v2, with documentation corrections for partition roots

- Per-cpu workqueues are built through the same attribute path as
unbound ones and get a max_active of their own, continuing the work
to turn them into an affinity scope of unbound workqueues.

and rescue events, and BH workers yielding with work pending.

"Highlight:
- Don't leak local kernel addresses (and complement the ongoing
rhashtable migration) (Kyle Zeng)
The index value for the associative array has been calculated with
the following formula:
mult_64x32_and_fold(description + type address + domain address)
By creating a sequence of dummy keys (e.g., "A", "B", "C", ...), it
is trivial to form a group of equations with a predictable hash
function, and ultimately break KASLR.
Kyle's solution is based on an ephemeral SipHash key and an atomic
64-bit counter, which is encapsulated to a key_index_id(). This

Pull IPE updates from Fan Wu:
- Fix an extra empty audit record on enforcement changes
ipe_audit_enforce() started an audit buffer but logged the state
change with audit_log(), which emits its own record. Ending the
unused buffer produced an additional empty AUDIT_MAC_STATUS record
every time the enforcement state was changed.
- Keep the name and token tables in sync with their enums
The audit name tables now use designated initializers, so each name
stays bound to its enum value, and static assertions on the policy
parser token tables break the build if an enum value is added without
a matching token.
- Constify token_default() and correct a comment about policy text

Pull alpha floating point emulation fix from Matt Turner:
"Make the FP emulation determine tininess after rounding, as the
hardware does.
soft-fp always determined it before rounding, so an operation that
trapped for software completion could report an underflow the same
operation would not report when it did not trap. glibc's math
testsuite catches the disagreement.
This adds _FP_TININESS_AFTER_ROUNDING to the shared soft-fp code in
include/math-emu/, as glibc's copy already has, and sets it only for
alpha. It defaults to zero, so powerpc, sh and sparc are unchanged.
This is the last patch of a three-patch series; the first two were
