This extends the BPF trampoline JIT to support attachment to functions that take small structures (up to 128bit) as argument. This is trivially achieved by saving/restoring a number of "argument registers" rather than a number of arguments. The AAPCS64 section 6.8.2 describes the parameter passing ABI. "Composite types" (like C structs) below 16 bytes (as enforced by the BPF verifier) are provided as part of the 8 argument registers as explained in the section C.12.
