Wanpeng Li f38a7b7526 KVM: X86: support paravirtualized help for TLB shootdowns 
When running on a virtual machine, IPIs are expensive when the target
CPU is sleeping.  Thus, it is nice to be able to avoid them for TLB
shootdowns.  KVM can just do the flush via INVVPID on the guest's behalf
the next time the CPU is scheduled.
