By default, sparse assumes a 64bit machine when compiled on x86-64 and 32bit when compiled on anything else.
This can of course create all sort of problems, like issuing false warnings like: 'shift too big (32) for type unsigned long', or worse, to not emit legitimate warnings.
Fix this by passing to sparse the appropriate -m32/-m64 flag
