Bug Description
As reported by Alex Thorlton <email address hidden>:
This mainline commit (part of the fix for CVE-2019-3016) was accidentally omitted from Bionic when the rest of that fix was applied in 4.15.0-106.107:
b043138246a4 x86/KVM: Make sure KVM_VCPU_FLUSH_TLB flag is not missed
That commit (actually its 4.19-stable backport) further requires the following (which all require light backports too):
858a43aae236 KVM: X86: use paravirtualized TLB Shootdown
fa55eedd6328 KVM: X86: Add KVM_VCPU_PREEMPTED
f38a7b75267f KVM: X86: support paravirtualized help for TLB shootdowns
