Sandipan Das f84192ee00 tools: bpftool: resolve calls without using imm field ... Currently, we resolve the callee's address for a JITed function call by using the imm field of the call instruction as an offset from __bpf_call_base. If bpf_jit_kallsyms is enabled, we further use this address to get the callee's kernel symbol's name. For some architectures, such as powerpc64, the imm field is not large enough to hold this offset. So, instead of assigning this offset to the imm field, the verifier now assigns the subprog id. Also, a list of kernel symbol addresses for all the JITed functions is provided in the program info. We now use the imm field as an index for this list to lookup a callee's symbol's address and resolve its name.
