My questions in comment #1 where no answered directly yet, but this
still is using only kernel patches so far, I think it is time to add at
least a kernel task.
Furthermore it isn't upstream yet and the target being 5.2 is a bit out
still, so I'd think you should target 19.10

Title:
KVM SnowRidge Split-lock disable
Status in linux package in Ubuntu:
Incomplete
Status in qemu package in Ubuntu:
New
Bug description:
When bit 29 is set in Test Control MSR register 0x33, a #AC execption
is generated for split locked accesses at all CPL irrespective of
CR0.AM or EFLAGS.AC.
This feature can help developers to capture memory accesses that
across cachelines with #LOCK assertion. Then developers can
reconstruct their program accordingly
Upstream target linux 5.2
Target Release: 19.04
