turbostat: Don't attempt to printf an off_t with %zx
turbostat uses the format %zx to print an off_t. However, %zx wants a size_t, not an off_t. On 32-bit targets, those refer to different types, potentially even with different sizes. Use %llx and a cast instead, since printf does not have a length modifier for off_t. Without this patch, when compiling for a 32-bit target: turbostat.c: In function 'get_msr': turbostat.c:231:3: warning: format '%zx' expects argument of type 'size_t', but argument 4 has type 'off_t' [-Wformat] Signed-off-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Len Brown <len.brown@intel.com>
