I have pushed my old kernel patches to a git tree at:

git://git.kernel.org//pub/scm/linux/kernel/git/hpa/linux-2.6-ilp32.git

They are currently based on 2.6.31 since that was the released version
when I first did this work; they are not intended to be mergeble but
rather as a prototype.

Note that we have no intention of supporting this ABI for the kernel
itself.  The kernel will be a normal x86-64 kernel.
