# gpg:                 aka "Paolo Bonzini <bonzini@gnu.org>"

* remotes/kvm/tags/for-upstream:
  mc146818rtc: reinitialize irq_reinject_on_ack_count on reset
  target-i386: Add "tsc_adjust" CPU feature name
  target-i386: Add "mpx" CPU feature name
  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
  cpus: Define callback for QEMU "nmi" command
  kvm: run cpu state synchronization on target vcpu thread
