Bug#874536: linux: arm64ilp32 support
Source: linux
Version: 4.9.30-2+deb9u2.1
Severity: wishlist
Tags: patch
Attached are the packaging changes needed to make the kernel build for arm64ilp32.
The arm64ilp32 (aarch64-linux-gnu_ilp32) kernel support is not yet
merged upstream, so I guess you are not going to include this until it
is, but as I've done the work, it's useful to file this patch so you
have the necessary info to hand when the time comes.
I also have a corresponding patch for the kernel support, but it's
large, so I'll just point to it here, for anyone that wants to build this in debian:

Status for the port (in Debian) is tracked here: https://wiki.debian.org/Arm64ilp32Port
