v1 -> v2:
	* Patch# 1 is new and is not directly related to this patchset.
	* Patch# 2 now tracks only those guest-entries that pass all
	  checks in hardware and make it to guest code.
	* Patch# 3 removes the 'nested_guest_running' statistic that was
	  added in v1 and instead adds a stat that tracks how many VCPUs
	  have run a nested guest.

[PATCH 1/4 v2] KVM: nVMX: Reset 'nested_run_pending' only in guest mode
[PATCH 2/4 v2] KVM: nVMX: nSVM: 'nested_run' should count guest-entry
[PATCH 3/4 v2] KVM: nVMX: nSVM: Add a new debugfs statistic to show how
[PATCH 4/4 v2] KVM: x86: Add a new VM statistic to show number of VCPUs
