riscv: define CREATE_TRACE_POINTS in ptrace.c
Define CREATE_TRACE_POINTS in order to create functions and structures for the trace events. This is needed if HAVE_SYSCALL_TRACEPOINTS and CONFIG_FTRACE_SYSCALLS are enabled, otherwise we get linking errors: [..] MODPOST vmlinux.o kernel/trace/trace_syscalls.o: In function `.L0 ': trace_syscalls.c:(.text+0x1152): undefined reference to `__tracepoint_sys_enter' trace_syscalls.c:(.text+0x126c): undefined reference to `__tracepoint_sys_enter' trace_syscalls.c:(.text+0x1328): undefined reference to `__tracepoint_sys_enter' trace_syscalls.c:(.text+0x14aa): undefined reference to `__tracepoint_sys_enter' trace_syscalls.c:(.text+0x1684): undefined reference to `__tracepoint_sys_exit' trace_syscalls.c:(.text+0x17a0): undefined reference to `__tracepoint_sys_exit' trace_syscalls.c:(.text+0x185c): undefined reference to `__tracepoint_sys_exit' trace_syscalls.c:(.text+0x19de): undefined reference to `__tracepoint_sys_exit' arch/riscv/kernel/ptrace.o: In function `.L0 ': ptrace.c:(.text+0x4dc): undefined reference to `__tracepoint_sys_enter' ptrace.c:(.text+0x632): undefined reference to `__tracepoint_sys_exit' make: *** [Makefile:1036: vmlinux] Error 1 Signed-off-by: David Abdurachmanov <david.abdurachmanov@gmail.com> Fixes: b78002b395b4 ("riscv: add HAVE_SYSCALL_TRACEPOINTS to Kconfig") Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
