v4 -> v5:
        1. The fix in patch# 1 has been modified. We are queue'ing the
           pending #DB intercept via nested_svm_vmexit() if the VMRUN is
           found to be single-stepped.
        2. In patch# 3, the assembly label for tracking the VMRUN RIP has
           been changed to u64* from void*.

[PATCH 1/4 v5] KVM: nSVM: If VMRUN is single-stepped, queue the #DB
[PATCH 2/4 v5] KVM: X86: Add a utility function to read current RIP
[PATCH 3/4 v5] KVM: nSVM: Add assembly label to VMRUN instruction
[PATCH 4/4 v5] nSVM: Test effect of host RFLAGS.TF on VMRUN
