Nathan Chancellor 8829b6ccf4 x86/boot: Add $(CLANG_FLAGS) to compressed KBUILD_CFLAGS ... [ Upstream commit d5cbd80e302dfea59726c44c56ab7957f822409f ] When cross compiling x86 on an ARM machine with clang, there are several errors along the lines of: arch/x86/include/asm/string_64.h:27:10: error: invalid output constraint '=&c' in asm This happens because the compressed boot Makefile reassigns KBUILD_CFLAGS and drops the clang flags that set the target architecture ('--target=') and the path to the GNU cross tools ('--prefix='), meaning that the host architecture is targeted. These flags are available as $(CLANG_FLAGS) from the main Makefile so add them to the compressed boot folder's KBUILD_CFLAGS so that cross compiling works as expected.
