There don't seem to be thousands of warnings anymore.

Maybe it's time to default enable it when using C=?

from: Documentation/sparse.txt:

The optional make variable CF can be used to pass arguments to sparse.  The
build system passes -Wbitwise to sparse automatically.  To perform endianness
checks, you may define __CHECK_ENDIAN__:

        make C=2 CF="-D__CHECK_ENDIAN__"

These checks are disabled by default as they generate a host of warnings.
