    * Some TCG emulation fixes and performance improvements
    * Support for the mffsl instruction in TCG
    * Added missing DPDES SPR
    * Some enhancements to the emulation of the XIVE interrupt
      controller
    * Cleanups to spapr MSI management
    * Some new suspend/resume infrastructure and a draft suspend
      implementation for spapr
