[PATCH] x86_64: Allow compilation on a 32bit biarch toolchain
This might help on distributions that use a 32bit biarch compiler. First pass -m64 by default. Secondly add some more .code32s because at least the Ubuntu biarch 32bit as called by gcc doesn't seem to handle -m64 -m32 as generated by the Makefile without such assistance. And finally make sure the linker script can be preprocessed with a 32bit cpp. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
