Pull bpf updates from Alexei Starovoitov:

- Support associating BPF program with struct_ops (Amery Hung)

- Switch BPF local storage to rqspinlock and remove recursion detection
counters which were causing false positives (Amery Hung)

- Fix live registers marking for indirect jumps (Anton Protopopov)

- Introduce execution context detection BPF helpers (Changwoo Min)

- Improve verifier precision for 32bit sign extension pattern
(Cupertino Miranda)

- Optimize BTF type lookup by sorting vmlinux BTF and doing binary
search (Donglin Peng)

- Allow states pruning for misc/invalid slots in iterator loops (Eduard
Zingerman)

- In preparation for ASAN support in BPF arenas teach libbpf to move
global BPF variables to the end of the region and enable arena kfuncs
while holding locks (Emil Tsalapatis)

- Introduce support for implicit arguments in kfuncs and migrate a
number of them to new API. This is a prerequisite for cgroup
sub-schedulers in sched-ext (Ihor Solodrai)

- Fix incorrect copied_seq calculation in sockmap (Jiayuan Chen)

- Fix ORC stack unwind from kprobe_multi (Jiri Olsa)

- Speed up fentry attach by using single ftrace direct ops in BPF
trampolines (Jiri Olsa)

- Require frozen map for calculating map hash (KP Singh)

- Fix lock entry creation in TAS fallback in rqspinlock (Kumar
Kartikeya Dwivedi)

- Allow user space to select cpu in lookup/update operations on per-cpu
array and hash maps (Leon Hwang)

- Make kfuncs return trusted pointers by default (Matt Bobrowski)

- Introduce "fsession" support where single BPF program is executed
upon entry and exit from traced kernel function (Menglong Dong)

- Allow bpf_timer and bpf_wq use in all programs types (Mykyta
Yatsenko, Andrii Nakryiko, Kumar Kartikeya Dwivedi, Alexei
Starovoitov)

- Make KF_TRUSTED_ARGS the default for all kfuncs and clean up their
definition across the tree (Puranjay Mohan)

- Allow BPF arena calls from non-sleepable context (Puranjay Mohan)

- Improve register id comparison logic in the verifier and extend
linked registers with negative offsets (Puranjay Mohan)

- In preparation for BPF-OOM introduce kfuncs to access memcg events
(Roman Gushchin)

- Use CFI compatible destructor kfunc type (Sami Tolvanen)

- Add bitwise tracking for BPF_END in the verifier (Tianci Cao)

- Add range tracking for BPF_DIV and BPF_MOD in the verifier (Yazhou
Tang)

- Make BPF selftests work with 64k page size (Yonghong Song)
