There has been some confusion/mixup. What I want to do is add a
qemuarmv5 which is the current qemuarm and then switch qemuarm to be
the a15 based one.

Something like:

I put KMACHINE mappings in the machine definitions, this patch isn't
well tested as yet and builds on the qemuarma14 patch in -next.

Jon won't get to that until Monday and I'm travelling so will be a bit
disrupted. I'm testing what I can before I leave.

qemumarm64 graphics works with the 4.19 kernel but not 5.0.

The only other issue I'm aware of is stap failing on qemuarm (old v5
version).
