41a23ab336 KVM: selftests: do not substitute SVM/VMX check with KVM_CAP_NESTED_STATE check 
state_test/smm_test use KVM_CAP_NESTED_STATE check as an indicator for
nested VMX/SVM presence and this is incorrect. Check for the required
features dirrectly.

ctrl_exit_rev/ctrl_pin_rev/basic variables are only used in
vmx_preemption_timer_test.c, just move them there.

When a nested VM with a VMX-preemption timer is migrated, verify that the
nested VM and its parent VM observe the VMX-preemption timer exit close to
the original expiration deadline.

0944442045 selftests: kvm: add test for dirty logging inside nested guests 
Check that accesses by nested guests are logged according to the
L1 physical addresses rather than L2.

Most of the patch is really adding EPT support to the testing
framework.
