systemd: work around the boot problem on qemuarm64
cover systemd: work around the boot problem on qemuarm64
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)
