Message

v2 -> v3:
	* Patch "KVM: nVMX: Reset 'nested_run_pending' only in guest
	  mode" from v2 has been dropped.
	* Patch "KVM: nVMX: nSVM: Add a new debugfs statistic to show how
	  many VCPUs have run nested guests" from v2 has been reverted back
	  to what it was in v1 where the statistic tracks if the VCPU
	  is currently executing in guest mode. This modifiled patch is
	  patch# 2 in v3. The name of the statistic has been changed to
	  'guest_mode' to better reflect what it is for.
	* The name of the statistic in patch# 3 has been changed to 'vcpus'.

[PATCH 1/3 v3] KVM: nVMX: nSVM: 'nested_run' should count guest-entry
[PATCH 2/3 v3] KVM: nVMX: nSVM: Add a new VCPU statistic to show if VCPU
[PATCH 3/3 v3] KVM: x86: Add a new VM statistic to show number of VCPUs
