From 7cff7ce94a7df2ccf5ac76b48ee0995fee2060df Mon Sep 17 00:00:00 2001 From: Andrew Morton <akpm@linux-foundation.org> Date: Fri, 9 Oct 2009 00:01:39 -0700 Subject: [PATCH] include/linux/compiler-gcc4.h: Fix build bug - gcc-4.0.2 doesn't understand __builtin_object_size Maybe 4.1.0 doesn't too, but this fixed it for me. Caused by: 4a31276: x86: Turn the copy_from_user check into an (optional) compile time warning 9f0cf4a: x86: Use __builtin_object_size() to validate the buffer size for copy_from_user() Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Cc: Arjan van de Ven <arjan@linux.intel.com> LKML-Reference: <200910090724.n997OQl6013538@imap1.linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> --- include/linux/compiler-gcc4.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/include/linux/compiler-gcc4.h b/include/linux/compiler-gcc4.h index 77542c57e20a..e6ef279ca20c 100644 --- a/include/linux/compiler-gcc4.h +++ b/include/linux/compiler-gcc4.h @@ -38,7 +38,9 @@ #endif +#if __GNUC_MINOR__ > 0 #define __compiletime_object_size(obj) __builtin_object_size(obj, 0) +#endif #if __GNUC_MINOR__ >= 4 #define __compiletime_warning(message) __attribute__((warning(message))) #define __compiletime_error(message) __attribute__((error(message))) -- GitLab
