Re: a question about system call's return address...

This makes me think there is no caller for that system call. So,
the second question is "how does mmap2 get called any way if there is
no caller?"

I think mmap2 is always called by the `dynamic linker'(also known as
loader), which is /lib/ld-linux.so.2 at Linux. It calls mmap2 to load
all the shared libraries needed by your program.
