Partition the header include path flags into two sets, one for kernelspace builds and one for userspace builds. Add the following directories to build after the ordinary include directories so that #include will pick up the UAPI header directly if the kernel header has been moved there. The userspace set (represented by the USERINCLUDE make variable) contains: -I $(srctree)/arch/$(hdr-arch)/include/uapi -I arch/$(hdr-arch)/include/generated/uapi -I $(srctree)/include/uapi -I include/generated/uapi -include $(srctree)/include/linux/kconfig.h and the kernelspace set (represented by the LINUXINCLUDE make variable) contains: -I $(srctree)/arch/$(hdr-arch)/include -I arch/$(hdr-arch)/include/generated -I $(srctree)/include -I include --- if not building in the source tree plus everything in the USERINCLUDE set. Then use USERINCLUDE in building the x86 boot code.
