After commit faa16bc404d7 ("lib: Use existing define with polynomial") the lib/xz/xz_crc32.c includes a header from include/linux directory thus any other user of this code should define proper include path.
This fixes the build error on powerpc with CONFIG_KERNEL_XZ: In file included from ../arch/powerpc/boot/../../../lib/decompress_unxz.c:233:0, from ../arch/powerpc/boot/decompress.c:42: ../arch/powerpc/boot/../../../lib/xz/xz_crc32.c:18:29: fatal error: linux/crc32poly.h: No such file or directory Reported-by: Michal Kubecek <mkube...@suse.cz> Fixes: faa16bc404d7 ("lib: Use existing define with polynomial") Signed-off-by: Krzysztof Kozlowski <k...@kernel.org> --- Only compile tested. --- arch/powerpc/boot/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/powerpc/boot/Makefile b/arch/powerpc/boot/Makefile index 0fb96c26136f..ba4182fb185d 100644 --- a/arch/powerpc/boot/Makefile +++ b/arch/powerpc/boot/Makefile @@ -63,7 +63,7 @@ ifeq ($(call cc-option-yn, -fstack-protector),y) BOOTCFLAGS += -fno-stack-protector endif -BOOTCFLAGS += -I$(objtree)/$(obj) -I$(srctree)/$(obj) +BOOTCFLAGS += -I$(objtree)/$(obj) -I$(srctree)/$(obj) -I$(srctree)/include DTC_FLAGS ?= -p 1024 -- 2.7.4
