Yes, even though some of the executables are 64K aligned (eg /bin/bash
and I can use that as init= without an issue), I do not know why that's
the case or if I did something wrong while updating packages.

The following splat is from an aarch64 4.4-rc2 kernel, compiled with 64K pages
support, system can't reach
user space since systemd fails to execute (the same set-up works for 4K pages
kernel).
Freeing unused kernel memory: 576K (fe83 - fe8c)
Starting init: /sbin/init exi
And this is where I think the problem is, in particular the align field
for the LOAD headers.

Systemd init failure on arm64 64k pages

Public bug reported:
Some binaries in 15.10 for aarch64 seem to be compiled with maxpagesize=4K
which triggers issues when run on 64K pages
arm64 kernels (tested on all kernels back to 4.0). I spotted this while trying
to boot an arm64 kernel with 64K pages enabled on 15.10 Ubuntu filesystem.
