[PATCH v2 0/3] hvc/xen: Xen console fixes.

[David Woodhouse]

It started out relatively simple, fixing the fact that the secondary
consoles didn't work at *all* due to bugs in the IRQ setup. There were
one or two other simple fixes that I snuck into the same patch in v1.

But it's much more broken than that, so split the fixes out, especially
the last one for hot-unplug.

Preserving the Reviewed-by: from Jürgen on the first two seems fair;
the third patch is new and exciting but *does* fix the case of removing
the console while userspace is spamming it.

And all I really wanted to do this week was spin up a PV guest under KVM 
so I could play with its SMEP behaviour...
