Cool!

This should be echo -e in bash, but then it won't work in dash I guess. So better use multiple echo commands. Also please add the targets to 'make help' text and add coccicheck-% to the no-dot-config-targets variable.

Please use 'for file in $(srctree)/scripts/smpl/*.cocci; do ...', so that the reports are in a defined order. Or do you plan to use subdirectories below scripts/smpl?

Then you don't need to add the same comment to each of the *.cocci files. Also is it necessary to advertise
"More information about semantic patching is available at http://coccinelle.lip6.fr/"
before processing each *.cocci file? If you want the banner, you could append it to the "Please check for false positives..." text printed once in the beginning.

You can also print the URL here if the spatch command is not available.
