Aaron Tomlin fc076b5f48 perf trace: Introduce kernel symbol beautifier for virtual addresses ... Currently, when 'perf trace' formats tracepoint payloads or system call arguments containing raw kernel virtual addresses (e.g., a work item function pointer work_func_t in workqueue:workqueue_execute_start), it prints them as raw hexadecimal values (e.g., 0xffffffff81234567). This impairs readability when tracing kernel execution flows. Introduce a dedicated kernel symbol beautifier, syscall_arg__scnprintf_ksym (i.e., SCA_KSYM), to resolve kernel virtual addresses to human-readable symbol names and offsets (e.g., "flush_to_ldisc"). The beautifier looks up the virtual address in the machine kernel maps via machine__find_kernel_symbol(). If a valid kernel symbol is found, the symbol name and offset are printed without requiring --libtraceevent; if the address is zero, "NULL" is rendered; otherwise, it gracefully falls back to hexadecimal formatting.
