[2] Provide a way for resolving function calls because of the way JITed images are allocated in powerpc64. [3] Fix to get JITed instruction dumps for multi-function programs from the bpf system call. [4] Fix for bpftool to show delimited multi-function JITed image dumps. v4: - Incorporate review comments from Jakub. - Fix JSON output for bpftool. v3: - Change base tree tag to bpf-next. - Incorporate review comments from Alexei, Daniel and Jakub. - Make sure that the JITed image does not grow or shrink after the last pass due to the way the instruction sequence used to load a callee's address maybe optimized. - Make additional changes to the bpf system call and bpftool to make multi-function JITed dumps easier to correlate. v2: - Incorporate review comments from Jakub.
