Depends on audit patch:
http://lists.infradead.org/pipermail/linux-riscv/2018-October/001931.html
audit patch is already merged into linux-next.
This simply fixes compilation error in do_syscall_trace_exit() and
enables syscalls tracepoints.

I looked into Documentation/trace/ftrace-design.rst and, I think,
we check all the boxes needed for HAVE_SYSCALL_TRACEPOINTS.

I've attempted to add this on top of next-audit, which I've merged into
for-next. Let me know if something went wrong.

Two things:
- The order of commits are wrong. Right now the commits are in
reverse order, i.e. audit patches are on top.
- Intel kbuild test bot found compilation errors with riscv-allmodconfig
config. I fixed those and posted two patches:
