From: Jaroslav Jindrak <jjindrak@suse.cz>

One of the warnings in out_write_cpu_data() printfs two
unsigned long long values as signed long long:

	tracecmd_warning("did not match size of %lld to %lld",
			 read_size, data_files[i].file_size);

This can lead to misleading values in a warning:

libtracecmd: Invalid argument
  did not match size of 3451486208 to -843481088
