Merge tag 'v7.2-rc1' into drm-rust-next

Merge v7.2-rc1 into drm-rust-next to start the next cycle.

Devres now requires T: 'static, which conflicts with shmem::Object using
Devres<SGTableMap<T, C>> without that bound. Resolve by adding 'static
as a supertrait to DriverObject and DeviceContext, which does not
restrict any current use cases since DriverObject is always implemented
on owned, refcounted types and DeviceContext is a sealed marker trait
with only unit-type implementors.

If DriverObject (or DeviceContext) ever becomes lifetime-parameterized
(e.g. via a GAT for TTM backed objects), the 'static supertrait can be
relaxed at that point.

drop the unused initializer in the platform_device_id table for
sh_mtu2 (Uwe Kleine-König)

- Remove redundant dev_err()/dev_err_probe() messages when
devm_request_*_irq() fails, as the helper already logs an error
message (Pan Chuang)

with the sun4i timer (Felix Yan)

- Fix an IRQ leak in the cpuhp_setup_state() error path by freeing the
IRQ on failure in the NXP PIT driver (WenTao Liang)

- Fix incorrect unmapping of shared MMIO between the clocksource and
clockevent drivers. If one of them fails to initialize, the error
path unmaps the shared MMIO region, leaving the other driver with an
invalid mapping on clps711x (Guangshuo Li)

regular spinlocks with raw_spinlock_t in atomic contexts (Marek

Merge tag 'bpf-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Pull bpf updates from Alexei Starovoitov:
"Major changes:

- Recover from BPF arena page faults using a scratch page and add
ptep_try_set() for lockless empty-slot installs on x86 and arm64.

This allows BPF kfuncs to access arena pointers directly.

The 'arena_direct_access' stable branch was created for this work
and was pulled into sched-ext and bpf-next trees (Tejun Heo, Kumar
Kartikeya Dwivedi)

- Lift old restriction and support 6+ arguments in BPF programs and
kfuncs on x86 and arm64 (Yonghong Song, Puranjay Mohan)

Other features and fixes:

- Add 24-bit BTF vlen and reclaim unused bits in the BTF UAPI to ease
addition of new BTF kinds (Alan Maguire)

- Raise the maximum BPF call chain depth from 8 to 16 frames (Alexei
Starovoitov)

- Refactor object relationship tracking in the verifier and fix a
dynptr use-after-free bug (Amery Hung)

- Harden the signed program loader and reject exclusive maps as inner
maps (Daniel Borkmann)

- Replace the verifier min/max bounds fields with a circular number
(cnum) representation and improve 32->64 bit range refinements
(Eduard Zingerman)

- Introduce the arena library and runtime (libarena) with a buddy
allocator, rbtree and SPMC queue data structures, ASAN support and
a parallel test harness. Allow subprograms to return arena pointers
and switch to a BTF type-tag based __arena annotation (Emil
Tsalapatis)

- Cache build IDs in the sleepable stackmap path and avoid faultable
build ID reads under mm locks (Ihor Solodrai)

- Introduce the tracing_multi link to attach a single BPF program to
many kernel functions at once. Allow specifying the uprobe_multi
target via FD (Jiri Olsa)

- Extend the bpf_list family of kfuncs with bpf_list_add/del(), and
bpf_list_is_first/is_last/empty() (Kaitao Cheng)

- Extend the BPF syscall with common attributes support for
prog_load, btf_load and map_create (Leon Hwang)

- Wrap rhashtable as BPF map (Mykyta Yatsenko, Herbert Xu)

- Add sleepable support for tracepoint programs and fix deadlocks in
LRU map due to NMI reentry (Mykyta Yatsenko)

- Fix OOB access in bpf_flow_keys, fix nullness analysis of inner
arrays, enforce write checks for global subprograms (Nuoqi Gui)

- Report the maximum combined stack depth and print a breakdown of
instructions processed per subprogram (Paul Chaignon)

- Add an XDP load-balancer benchmark and arm64 JIT support for stack
arguments (Puranjay Mohan)

- Add kfuncs to traverse over wakeup_sources (Samuel Wu)

- Allow sleepable BPF programs to use LPM trie maps directly (Vlad
Poenaru)

- Many more fixes and cleanups across the verifier, BTF, sockmap,
devmap, bpffs, security hooks, s390/riscv/loongarch JITs,
rqspinlock, libbpf, bpftool, selftests"

selftests/bpf: Test signed loader error paths

The positive path for signed BPF loaders is covered today by the
signed lskels (fentry_test, fexit_test, atomics).

But the runtime metadata check the generated loader performs (libbpf
gen_loader's emit_signature_match), the map content hash it relies
on, the load-time signature, and the immutability invariants of its
metadata map are not yet covered.

Thus, add a new, extensive test suite which drives libbpf's gen_loader
(bpf_object__gen_loader, gen_hash=true), the same machinery which
bpftool uses for signed light skeletons, and exercise corner cases
so that we can assert this in BPF CI:
