Rather than adding prototypes for C functions called only by assembly code, mark them as __visible. This avoids adding prototypes that will never be used by the callers. Resolves the following sparse warnings:
arch/riscv/kernel/ptrace.c:151:6: warning: symbol 'do_syscall_trace_enter' was not declared. Should it be static? arch/riscv/kernel/ptrace.c:175:6: warning: symbol 'do_syscall_trace_exit' was not declared. Should it be static? Based on a suggestion from Luc Van Oostenryck.
