Finding a line of code in the Kernel from a stack trace

To find out what line a particular stack trace entry points to, use the script ./scripts/faddr2line for example If I have the line __get_vm_area_node+0x17c/0x1a8 I can run

./scripts/faddr2line vmlinux.o __get_vm_area_node+0x17c/0x1a8
__get_vm_area_node at /root/linux/mm/vmalloc.c:2579 (discriminator 1)
