From: Krzysztof Kozlowski Date: Wed, 29 Aug 2018 09:32:23 +0200 Subject: powerpc/boot: Fix missing crc32poly.h when building with KERNEL_XZ Origin: https://patchwork.ozlabs.org/patch/963258/ 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 Fixes: faa16bc404d7 ("lib: Use existing define with polynomial") Signed-off-by: Krzysztof Kozlowski Reported-by: kbuild test robot Reported-by: Meelis Roos Tested-by: Michal Kubecek --- arch/powerpc/boot/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) Index: linux/arch/powerpc/boot/Makefile =================================================================== --- linux.orig/arch/powerpc/boot/Makefile +++ linux/arch/powerpc/boot/Makefile @@ -70,7 +70,7 @@ BOOTCFLAGS += -fno-stack-protector endif BOOTCFLAGS += -include $(srctree)/include/linux/compiler_attributes.h -BOOTCFLAGS += -I$(objtree)/$(obj) -I$(srctree)/$(obj) +BOOTCFLAGS += -I$(objtree)/$(obj) -I$(srctree)/$(obj) -I$(srctree)/include DTC_FLAGS ?= -p 1024
