There don't seem to be thousands of warnings anymore.
Maybe it's time to default enable it when using C=?
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.
