Second batch of KVM changes for 4.11 merge window

PPC:
  * correct assumption about ASDR on POWER9
  * fix MMIO emulation on POWER9
 
 x86:
  * add a simple test for ioperm
  * cleanup TSS
    (going through KVM tree as the whole undertaking was caused by VMX's
     use of TSS)
  * fix nVMX interrupt delivery
  * fix some performance counters in the guest
 
 And two cleanup patches.
