  vl: process -object after other backend options
  checkpatch.pl: adjust typedef definition to QEMU coding style
  x86: Clear MTRRs on vCPU reset
  x86: kvm: Add MTRR support for kvm_get|put_msrs()
  x86: Use common variable range MTRR counts
  target-i386: Don't forbid NX bit on PAE PDEs and PTEs
  spapr: Add support for new NMI interface
  s390x: Migrate to new NMI interface
  s390x: Convert QEMUMachine to MachineClass
