From: Aurelien Jarno <aurelien@xxxxxxxxxxx> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 29593fd5a8149462ed6fad0d522234facdaee6c8 upstream. Commit dc4d7b37 (MIPS: ZBOOT: gather string functions into string.c) moved the string related functions into a separate file, which might cause the following build error, depending on the configuration: | CC arch/mips/boot/compressed/decompress.o | In file included from linux/arch/mips/boot/compressed/../../../../lib/decompress_unxz.c:234:0, | from linux/arch/mips/boot/compressed/decompress.c:67: | linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c: In function 'fill_temp': | linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c:162:2: error: implicit declaration of function 'memcpy' [-Werror=implicit-function-declaration] | cc1: some warnings being treated as errors | linux/scripts/Makefile.build:308: recipe for target 'arch/mips/boot/compressed/decompress.o' failed | make[6]: *** [arch/mips/boot/compressed/decompress.o] Error 1 | linux/arch/mips/Makefile:308: recipe for target 'vmlinuz' failed It does not fail with the standard configuration, as when CONFIG_DYNAMIC_DEBUG is not enabled <linux/string.h> gets included in include/linux/dynamic_debug.h. There might be other ways for it to get indirectly included. We can't add the include directly in xz_dec_stream.c as some architectures might want to use a different version for the boot/ directory (see for example arch/x86/boot/string.h).
