linux: fix the KNL cache depth when exposed as a memory-side cache
Should be 1, instead of inheriting 3 from the CPU-cache case.

lstopo: Add output option for LaTeX tikzpicture
This output option generates a standalone picture to be compiled with 
pdflatex.  The colors are defined using the xcolor package.  If only the 
tikzpicture is of interest, one can extract the image code by copying 
the lines between
"%%%%% If inserting in another document, this is the actual source code
of the picture %%%%%" and
"%%%%% End of actual source code of the picture to insert in another
document %%%%%", however, some lines also have to be copied to the
document preambule.
