Well - the effort done for sparc and m68k lately was also needed. > Your kbuild patches > are making quite a bit of difference so please dont hold back :) The good patches are the ones that benefits all architectures. Well - I can give the vmlinux_*.ds files a try. Did you apply the patch to an append only branch or may I recreate the patch? I noticed a few minor things that can be 'fixed' to bring the inital differences between 32 bit and 64 bit down. But I can do these in a follow-up patch too.
