    The main changes are:
    
    1) Add BPF JIT support for 32-bit ARCv2 processors, from Shahab Vahedi.
    
    2) Add BPF range computation improvements to the verifier in particular
       around XOR and OR operators, refactoring of checks for range computation
       and relaxing MUL range computation so that src_reg can also be an unknown
       scalar, from Cupertino Miranda.
    
    3) Add support to attach kprobe BPF programs through kprobe_multi link in
       a session mode, meaning, a BPF program is attached to both function entry
       and return, the entry program can decide if the return program gets
       executed and the entry program can share u64 cookie value with return
       program. Session mode is a common use-case for tetragon...
