Fix for a brutal segment caching bug that manifested as random nested
VM-Enter failures when running with unrestricted guest disabled.  A few
more bug fixes and cleanups for stuff found by inspection when hunting
down the caching issue.

v2:
  - Rebased to kvm/queue, commit e1ba1a15af73 ("KVM: SVM: Enable INVPCID
    feature on AMD").

Sean Christopherson (7):
  KVM: nVMX: Reset the segment cache when stuffing guest segs
  KVM: nVMX: Reload vmcs01 if getting vmcs12's pages fails
  KVM: nVMX: Explicitly check for valid guest state for !unrestricted
    guest
  KVM: nVMX: Move free_nested() below vmx_switch_vmcs()
  KVM: nVMX: Ensure vmcs01 is the loaded VMCS when freeing nested state
  KVM: nVMX: Drop redundant VMCS switch and free_nested() call
  KVM: nVMX: WARN on attempt to switch the currently loaded VMCS
