Hi Kees,
sparse (make C=1) gives me this warnings today...
./include/linux/overflow.h:254:13: error: undefined identifier '__builtin_mul_overflow' ./include/linux/overflow.h:254:13: error: incorrect type in conditional ./include/linux/overflow.h:254:13: got void ./include/linux/overflow.h:256:13: error: undefined identifier '__builtin_add_overflow' ./include/linux/overflow.h:256:13: error: incorrect type in conditional ./include/linux/overflow.h:256:13: got void
This hunk obviously fixes it, but I'm really not sure if it is a proper fix.
