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.

the entire tool callback chain

- Switch architecture detection from string-based perf_env__arch()
comparisons to the numeric ELF e_machine field across the codebase
(capstone, print_insn, c2c, lock-contention, sort, sample-raw,

bounds checks and byte-swap validation for session records, feature
sections, header attributes, BPF metadata, auxtrace errors,
compressed events, CPU maps, build ID notes, and ELF program headers.
Add minimum event size validation and file offset diagnostics

- Fix libdw API contract violations across dwarf-aux, libdw,
probe-finder, annotate-data, and debuginfo subsystems. Fix callchain
parent update in ORDER_CALLER mode, support DWARF line 0 in inline

buffer overflow in parse_hwmon_filename(), fd 0 check, empty label
reads, scnprintf usage

iteration, validate p_filesz, fix 32-bit ELF bswap error, fix signed
overflow in size checks, bounds-check .gnu_debuglink section

perf build: Move BPF skeleton generation out of Makefile.perf

Currently, the top-level Makefile.perf defines a massive global bpf-skel
umbrella target that pre-compiles all 12+ BPF skeletons (%.skel.h) upfront
before launching sub-makes. This forces unrelated sub-makes to serialize
behind bpftool and clang BPF target evaluations, causing parallel build
bottlenecks.

Furthermore, bench_uprobe.bpf.c lived inside util/bpf_skel/, breaking
conceptual directory encapsulation since it is consumed purely by
bench/uprobe.c.

Refactor the BPF skeletons to better achieve directory isolation:
1. Move tools/perf/util/bpf_skel/bench_uprobe.bpf.c directly into
tools/perf/bench/bpf_skel/.
2. Extract the skeleton generation infrastructure out of Makefile.perf into
a shared inclusion file tools/perf/bpf_skel.mak.
3. Include bpf_skel.mak locally inside tools/perf/util/Build and
tools/perf/bench/Build and bind precise local prerequisites.
4. Safely synchronize the shared bpftool bootstrap and vmlinux.h targets
via the conditional prepare: umbrella to avoid parallel sub-make races,
while evaluating the actual skeletons completely locally on demand. A
later patch will move these targets into bpf_skel.mak.
5. Export CLANG from the global Makefile to ensure accurate tool
propagation.
6. Clean up Makefile.perf by stripping the global bpf-skel umbrella target
and its SKELETONS list.

While removing code from Makefile.perf generally helps build
performance, the impact here is minimal. The main motivation for the
change is to better encapsulate things in the build and simplify
Makefile.perf that has around 50 lines removed.

prctl(PR_FUTEX_HASH, PR_FUTEX_HASH_SET_SLOTS, buckets, immutable)

The size of the private hash is verified with PR_FUTEX_HASH_GET_SLOTS.
If PR_FUTEX_HASH_GET_SLOTS failed then it is assumed that an older
kernel was used without the support and that the global hash is used.
