How to view the addresses of kernel functions and system calls?

is there any way to get dump of linux kernel. I want to view the addresses of kernel functions and system call.

I am trying to hack the system call table. I need to redirect every read and write through my lkm.

From linux 2.6 they don't export system call开发者_开发技巧 table. So, I am trying to find the address.

You need a debugging version of the vmlinux file, which is produced when compiling the kernel. Some distributions have that file in a debugging package for their kernel. See also this and this.
