description:
Add cscope and mkid (and cscope.out and ID) targets to kernel compile
Makefiles. The main feature added by these targets is that they cover
ONLY the source files used for a given kernel and no other. Thus when
examining MD routines provided by all machines, you will see only
those applicable for your kernel.
