From e2862c9470beb842d3f1c1965b03a2112114c160 Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Mon, 27 Oct 2008 17:43:28 +1100 Subject: [PATCH] trace: fix printk warning for u64 A powerpc ppc64_defconfig build produces these warnings: kernel/trace/ring_buffer.c: In function 'rb_add_time_stamp': kernel/trace/ring_buffer.c:969: warning: format '%llu' expects type 'long long unsigned int', but argument 2 has type 'u64' kernel/trace/ring_buffer.c:969: warning: format '%llu' expects type 'long long unsigned int', but argument 3 has type 'u64' kernel/trace/ring_buffer.c:969: warning: format '%llu' expects type 'long long unsigned int', but argument 4 has type 'u64' Just cast the u64s to unsigned long long like we do everywhere else.
