Subject: [PATCH 0/2] KVM: nVMX: Skip IPBP on nested VMCS switch

Or as Jim would say, "Really skip IPBP on nested VMCS switch" :-D

Patch 1 is the delta between kvm/queue and v3 of the original patch[*],
i.e. I just cherry-picked v3 and fixed the conflicts.

Patch 2 applies the "no IPBP" logic to copy_vmcs02_to_vmcs12_rare().

Feel free to sqaush both of these to commit 7407a52f23732 ("KVM: nVMX:
Skip IBPB when switching between vmcs01 and vmcs02") if you so desire.
