Subject: [PATCH v3 0/2] KVM: count actual tlb flushes

* Instead of counting the number of coalesced flush requests,
  we count the actual tlb flushes.
* Flushes from kvm_flush_remote_tlbs will also be counted.
* Freeing the namespace a bit by replaces kvm_mmu_flush_tlb()
  with kvm_make_request() again.

---
v2 -> v3:

* split the patch into a series of two patches.
* rename the util function kvm_mmu_flush_tlb in x86.c to
  kvm_vcpu_flush_tlb

v1 -> v2:

* Instead of calling kvm_mmu_flush_tlb everywhere to make sure the
  stat is always incremented, postponing the counting to
  kvm_check_request.

  KVM: x86: directly use kvm_make_request again
