+Expose ARCH_CAP_MDS_NO in guest
+
+Description:
+
+MDS_NO is bit 5 of ARCH_CAPABILITIES. Expose this bit to guest.
+
+Target Qemu: 4.1
+
+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.
+
+This effort, if done, would be done together with:

+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.
