Do a kernel make with “make C=1” to run sparse on all the C files that get recompiled, or use “make C=2” to run sparse on the files whether they need to be recompiled or not. The latter is a fast way to check the whole tree if you have already built it. The optional make variable CF can be used to pass arguments to sparse.
