Pull bpf fixes from Alexei Starovoitov:

 - Fix BPF builds due to -fms-extensions. selftests (Alexei
   Starovoitov), bpftool (Quentin Monnet).

 - Fix build of net/smc when CONFIG_BPF_SYSCALL=y, but CONFIG_BPF_JIT=n
   (Geert Uytterhoeven)

 - Fix livepatch/BPF interaction and support reliable unwinding through
   BPF stack frames (Josh Poimboeuf)

 - Do not audit capability check in arm64 JIT (Ondrej Mosnacek)

 - Fix truncated dmabuf BPF iterator reads (T.J. Mercier)

 - Fix verifier assumptions of bpf_d_path's output buffer (Shuran Liu)

 - Fix warnings in libbpf when built with -Wdiscarded-qualifiers under
   C23 (Mikhail Gavrilov)
