Yes the reason is that it's the local flush and guest mode isn't
running if we're running that function so it's ok to run it later.
About the other change you did in this patch 2/2, I can't find the
code you're patching in the 3.2 upstream source, when I added the tlb
flush to invlpg, I immediately used a cumulative need_flush at the end
(before relasing mmu_lock of course).
if (need_flush)
kvm_flush_remote_tlbs(vcpu->kvm);
