perf kmem: Consistently use PRIu64 for printing u64 values
Building the perf tool for 32-bit ARM results in the following build error due to a combination of an incorrect conversion specifier and compiling with -Werror: builtin-kmem.c: In function ‘print_page_summary’: builtin-kmem.c:644:9: error: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 3 has type ‘u64’ [-Werror=format=] nr_alloc_freed, (total_alloc_freed_bytes) / 1024); ^ builtin-kmem.c:647:9: error: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 3 has type ‘u64’ [-Werror=format=] (total_page_alloc_bytes - total_alloc_freed_bytes) / 1024); ^ cc1: all warnings being treated as errors This patch fixes the problem by consistently using PRIu64 for printing out u64 values.
