I see that the kbuild robot and I were still not able to do successful builds even after this patch is applied. We were building different targets though. robot was doing kernel builds and I was doing a large "all-uapi" build. I started on my all-uapi work about 1 week ago but haven't posted anything yet, but it's posted (attached) below. It's not yet up to kernel quality yet (for a Makefile), and I have made very little progress toward a successful userspace build. If anyone is interested, just put these 3 files in <kernel_tree>/tools/build and then run: make ARCH=$some_arch O=build_dir headers_check so that the headers will be cleaned up and installed in build_dir/usr/. Then run 'make -f all-uapi.mk' and the userspace program with all header files found in build_dir/usr/include will be built -- i.e., attempted (not successfully). (note: chmod +x hdr-fix-lines.pl) -- ~Randy
