charset="UTF-8" _context_unsafe_alias() does not use its parameter 'p', which triggers -Wunused-parameter when building code that enables -Wextra (such as tools/perf, tools/lib/perf, tools/lib/subcmd, and tools/lib/symbol). Explicitly cast 'p' to void to silence the warning, matching __assume_ctx_lock() and __assume_shared_ctx_lock().
