- Fix for CVE-2020-27673 has not been backported yet.
Some kind of Xen issue, not really relevant to us, and fix is not

I'd say we can ignore this one.
This is queued for 4.19.155:

| a9d6e970261d 0891fb39ba67 o: | xen/events: don't use chip_data for legacy IRQs
| d103e667bb8c 073d0552ead5 o: | xen/events: avoid removing an event channel while handling it
| ed86a5182306 4d3fe31bd993 o: | xen/events: add a proper barrier to 2-level uevent unmasking
| 6e894d279f4e f01337197419 o: | xen/events: fix race in evtchn_fifo_unmask()
| 0279bd8ca365 54c9de89895e o: | xen/events: add a new "late EOI" evtchn framework

| 8b0ac9a498d2 c2711441bc96 .: | xen/pciback: use lateeoi irq binding
| 757d54717fae c44b849cee8c o: | xen/events: switch user event channels to lateeoi model
| c3c580896847 7beb290caa2a o: | xen/events: use a common cpu hotplug hook for event channels
| 7835cdf92784 e99502f76271 o: | xen/events: defer eoi in case of excessive number of events
| f8bf3977d67c 5f7f77400ab5 o: | xen/events: block rogue events for some time

"defer eoi" should be fix for this bug.

So..we don't need to do anything here, and it will get fixed.
