Not very sure exactly what information you are looking for. But I am
assuming you are looking for run time virtual and physical address of the
kernel.

For virtual address you can grab _text or _stext. Alternatively you can
parse /proc/kcore and look for ELF header where kernel is mapped.

Dave Anderson is already parsing /proc/kcore for determining kernel
virtual address in "crash" for x86_64  

For physical address you can look at /proc/iomem and grab "Kernel Code".
