The specific upstream commit is 20140a82c67467f53814ca197403d5e1b561a5e5
and is incorporated into qemu 1:3.1+dfsg-2ubuntu3.1 in disco-security
(19.04) and 1:3.1+dfsg-2ubuntu4 in eoan-proposed. For backporting to
cosmic and older, I believe it requires the infrastructure to support
IA32_ARCH_CAPABILITIES in place.

This is done upstream, no need for the upstream bug task.
For Ubuntu I'll update the tasks to match the statement of sbeattie.
There are discussions to reconsider some of the backports, but unfortunately the IA32_ARCH_CAPABILITIES infrastructure is a rather big set of changes.

I'm marking this bug as a duplicate of LP: #1828495 since both are
asking for mitigations pass-through to i386 kvm guests and I'm preparing
a fix for both simultaneously.
