Yep, nice stuff: linux-log-summary does nicely summarize it all like
this here:

...
include/linux/kernel.h:120:19: warning: cast from function call of type âvoid *â to non-matching type âlong unsigned intâ [-Wbad-function-cast]: 40 warnings in 1 logs
include/linux/kernel.h:67:27: warning: conversion to âintâ from âlong unsigned intâ may alter its value [-Wconversion]: 2 warnings in 1 logs
include/linux/kernel.h:67:33: warning: conversion to âlong unsigned intâ from âintâ may change the sign of the result [-Wsign-conversion]: 3 warnings in 1 logs
...

which I ran on a file built with W=123.

So I'd say everything needed is there to massage those build logs.

Thanks.
