The patch is missing an include statement: CC kernel/gcov/gcc_4_7.o kernel/gcov/gcc_4_7.c: In function gcov_info_dup: kernel/gcov/gcc_4_7.c:293:4: error: implicit declaration of function vmalloc [-Werror=implicit-function-declaration] kernel/gcov/gcc_4_7.c:293:20: warning: assignment makes pointer from integer without a cast [enabled by default] With that added, it compiles and works with gcc 4.3.4 and 4.7.2 on kernel 3.21-rc1 on s390x. --- a/kernel/gcov/gcc_4_7.c +++ b/kernel/gcov/gcc_4_7.c @@ -15,6 +15,7 @@ #include <linux/slab.h> #include <linux/string.h> #include <linux/seq_file.h> +#include <linux/vmalloc.h> #include "gcov.h" #define GCOV_COUNTERS 8 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
