From 6145c259cd454bcb7a1288f7bbb7b4fbc18175dd Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Thu, 23 Apr 2015 14:40:37 +0100 Subject: perf kmem: Consistently use PRIu64 for printing u64 values MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
