[PATCH v2 0/3] hvc/xen: Xen console fixes.
From: David Woodhouse
Date: Fri Oct 20 2023 - 12:16:05 EST
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...

hvc/xen: fix event channel handling for secondary consoles
hvc/xen: fix error path in xen_hvc_init() to always register frontend driver
