    OvmfPkg/CpuHotplugSmm: fix CPU hotplug race just after SMI broadcast
    
    The "virsh setvcpus" (plural) command may hot-plug several VCPUs in quick
    succession -- it means a series of "device_add" QEMU monitor commands,
    back-to-back.
    
    If a "device_add" occurs *just after* ACPI raises the broadcast SMI, then:
    
    - the CPU_FOREACH() loop in QEMU's ich9_apm_ctrl_changed() cannot make the
      SMI pending for the new CPU -- at that time, the new CPU doesn't even
      exist yet,
    
    - OVMF will find the new CPU however (in the CPU hotplug register block),
      in QemuCpuhpCollectApicIds().
    
    As a result, when the firmware sends an INIT-SIPI-SIPI to the new CPU in
    SmbaseRelocate(), expecting it to boot into SMM (due to the pending SMI),
    the new CPU instead boots straight into the post-RSM (normal mode) "pen",
    skipping its initial SMI handler.
    
    The CPU halts nicely in the pen, but its SMBASE is never relocated, and
    the SMRAM message exchange with the BSP falls apart -- the BSP gets stuck
    in the following loop:
    
      //
      // Wait until the hot-added CPU is just about to execute RSM.
      //
      while (Context->AboutToLeaveSmm == 0) {
        CpuPause ();
      }
    
    because the new CPU's initial SMI handler never sets the flag to nonzero.
    
    Fix this by sending a directed SMI to the new CPU just before sending it
    the INIT-SIPI-SIPI. The various scenarios are documented in the code --
    the cases affected by the patch are documented under point (2).
    
    Note that this is not considered a security patch, as for a malicious
    guest OS, the issue is not exploitable -- the symptom is a hang on the
    BSP, in the above-noted loop in SmbaseRelocate(). Instead, the patch fixes
    behavior for a benign guest OS.

    OvmfPkg/CpuHotplugSmm: fix CPU hotplug race just before SMI broadcast
    
    The "virsh setvcpus" (plural) command may hot-plug several VCPUs in quick
    succession -- it means a series of "device_add" QEMU monitor commands,
    back-to-back.
    
    If a "device_add" occurs *just before* ACPI raises the broadcast SMI,
    then:
    
    - OVMF processes the hot-added CPU well.
    
    - However, QEMU's post-SMI ACPI loop -- which clears the pending events
      for the hot-added CPUs that were collected before raising the SMI -- is
      unaware of the stray CPU. Thus, the pending event is not cleared for it.
    
    As a result of the stuck event, at the next hot-plug, OVMF tries to re-add
    (relocate for the 2nd time) the already-known CPU. At that time, the AP is
    already in the normal edk2 SMM busy-wait however, so it doesn't respond to
    the exchange that the BSP intends to do in SmbaseRelocate(). Thus the VM
    gets stuck in SMM.
    
    (Because of the above symptom, this is not considered a security patch; it
    doesn't seem exploitable by a malicious guest OS.)
    
    In CpuHotplugMmi(), skip the supposedly hot-added CPU if it's already
    known. The post-SMI ACPI loop will clear the pending event for it this
    time.
