There are very few files that need add an -I$(obj) gcc for the preprocessor or the assembler. For C files, we add always these for both the objtree and srctree, but for the other ones we require the Makefile to add them, and Kbuild then adds it for both trees. As a preparation for changing the meaning of the -I$(obj) directive to only refer to the srctree, this changes the two instances in arch/x86 to use an explictit $(objtree) prefix where needed, otherwise we won't find the headers any more, as reported by the kbuild 0day builder. arch/x86/realmode/rm/realmode.lds.S:75:20: fatal error: pasyms.h: No such file or directory Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx> --- arch/alpha/boot/Makefile | 2 +- arch/powerpc/boot/Makefile | 2 +- arch/powerpc/kvm/Makefile | 2 +- arch/s390/boot/compressed/Makefile | 4 ++-- arch/um/Makefile | 4 ++-- arch/x86/boot/Makefile | 2 +- arch/x86/realmode/rm/Makefile | 2 +- 7 files changed, 9 insertions(+), 9 deletions(-) diff --git a/arch/alpha/boot/Makefile b/arch/alpha/boot/Makefile index 8399bd0e68e8..0cbe4c59d3ce 100644 --- a/arch/alpha/boot/Makefile +++ b/arch/alpha/boot/Makefile @@ -15,7 +15,7 @@ targets := vmlinux.gz vmlinux \ OBJSTRIP := $(obj)/tools/objstrip HOSTCFLAGS := -Wall -I$(objtree)/usr/include -BOOTCFLAGS += -I$(obj) -I$(srctree)/$(obj) +BOOTCFLAGS += -I$(objtree)/$(obj) -I$(srctree)/$(obj) # SRM bootable image.
