[PATCH 0/1] systemd: work around the boot problem on qemuarm64

[Chen Qi]

The problem is that systemd based systems cannot boot on qemuarm64.

The patch is a workaround and I hope people who have more knowledge in this area
come up with a better fix.

The following changes since commit 8084c185c43cb7e7f5e29d31939dfd308f8a0f93:

  udev: Add 2 patches to support 4.4 kernel (2016-01-20 09:20:06 +0000)

are available in the git repository at:

This is general aarch64 problem, so make this across all aarch64
this is the original problem

And according to that link, is a binutils problem.  Can't we just fix that
instead?

Hi Khem and Ross,

I've verified the patch above does fix the systemd qemuarm64 problem.
Thanks all :)
