The return type of atomic64_read() varies by architecture. It may return long (e.g. powerpc), long long (e.g. arm), or s64 (e.g. x86_64). This is somewhat painful, and mandates the use of explicit casts in some cases (e.g. when printing the return value). To ameliorate matters, subsequent patches will make the atomic64 API consistently use s64. As a preparatory step, this patch updates the s390 pci debug code to treat the return value of atomic64_read() as s64, using an explicit cast. This cast will be removed once the s64 conversion is complete.
