Merge tag 'bpf-next-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Pull bpf updates from Alexei Starovoitov:
 "A smaller than usual release cycle.

  The main changes are:

   - Prepare selftest to run with GCC-BPF backend (Ihor Solodrai)

     In addition to LLVM-BPF runs the BPF CI now runs GCC-BPF in compile
     only mode. Half of the tests are failing, since support for
     btf_decl_tag is still WIP, but this is a great milestone.

   - Convert various samples/bpf to selftests/bpf/test_progs format
     (Alexis Lothoré and Bastien Curutchet)

   - Teach verifier to recognize that array lookup with constant
     in-range index will always succeed (Daniel Xu)

   - Cleanup migrate disable scope in BPF maps (Hou Tao)

   - Fix bpf_timer destroy path in PREEMPT_RT (Hou Tao)

   - Always use bpf_mem_alloc in bpf_local_storage in PREEMPT_RT (Martin
     KaFai Lau)

   - Refactor verifier lock support (Kumar Kartikeya Dwivedi)

     This is a prerequisite for upcoming resilient spin lock.

   - Remove excessive 'may_goto +0' instructions in the verifier that
     LLVM leaves when unrolls the loops (Yonghong Song)

   - Remove unhelpful bpf_probe_write_user() warning message (Marco
     Elver)

   - Add fd_array_cnt attribute for prog_load command (Anton Protopopov)

     This is a prerequisite for upcoming support for static_branch"
