From 7ea50d52849fe8ffa5b5b74c979b60b1045d6fc9 Mon Sep 17 00:00:00 2001 From: Jeroen Hofstee Date: Sat, 10 Aug 2013 17:16:50 +0200 Subject: compiler_gcc: do not redefine __gnu_attributes gcc allows extensions to be non compiler specific by defining __* macros for the attributes supported by gcc. Having a different definition causes many warnings during the build (cdefs.h on FreeBSD uses __attribute((__pure__)) where u-boot uses __attribute__((pure)) for example). Do not redefine these macros to suppress these warnings. This patch ignores the checkpatch warning: WARNING: __packed is preferred over __attribute__((packed)) Signed-off-by: Jeroen Hofstee --- include/linux/compiler-gcc4.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'include/linux/compiler-gcc4.h') diff --git a/include/linux/compiler-gcc4.h b/include/linux/compiler-gcc4.h index 94dea3ffbfa..27d11ca7b08 100644 --- a/include/linux/compiler-gcc4.h +++ b/include/linux/compiler-gcc4.h @@ -12,7 +12,9 @@ #define __used __attribute__((__used__)) #define __must_check __attribute__((warn_unused_result)) #define __compiler_offsetof(a,b) __builtin_offsetof(a,b) -#define __always_inline inline __attribute__((always_inline)) +#ifndef __always_inline +# define __always_inline inline __attribute__((always_inline)) +#endif /* * A trick to suppress uninitialized variable warning without generating any -- cgit v1.2.3
