So I have the vmlinux which was built with debugging symbols (I assume
this is why I got a backtrace as well)... however I'm not immediately
seeing how to trace this back into show_mem()

$ gdb vmlinux
(gdb) list *(show_mem+0x100)
0xa00000010005b9e0 is in show_mem (bitops.h:280).

277 static __inline__ int
278 test_bit (int nr, const volatile void *addr)
279 {
280 return 1 & (((const volatile __u32 *) addr)[nr >> 5] >> (nr & 31));
281 }
