From root Makefile:
# Use make M=dir to specify directory of external module to build
# Old syntax make ... SUBDIRS=$PWD is still supported
# Setting the environment variable KBUILD_EXTMOD take precedence

So, I compile all local modules as smth like
make -C ../../.. M=$PWD CONFIG_SMTH=m modules

If coccinelle is started as 'coccinelle $COCCI $M' then it checks only in
directory tree with $M root.
