From: Andi Kleen <ak@linux.intel.com>
In my set up (separate objdir, DEBUG=1) tip perf doesn't build without this change. It may be that in some other setups asm/bug.h is implicitely included. But always include it into builtin-stat.c
builtin-stat.c: In function ‘set_maps’: builtin-stat.c:2126:6: error: implicit declaration of function ‘WARN_ONCE’ [-Werror=implicit-function-declaration] if (WARN_ONCE(st->maps_allocated, "stats double allocation\n")) ^ builtin-stat.c:2126:2: error: nested extern declaration of ‘WARN_ONCE’ [-Werror=nested-externs] if (WARN_ONCE(st->maps_allocated, "stats double allocation\n")) ^
