* qemu-kvm/uq/master:
  target-i386: add feature kvm_pv_unhalt
  linux-headers: update to 3.12-rc1
  target-i386: forward CPUID cache leaves when -cpu host is used
  linux-headers: update to 3.11
  kvm: fix traces to use %x instead of %d
  kvmvapic: Clear also physical ROM address when entering INACTIVE state
  kvmvapic: Enter inactive state on hardware reset
  kvmvapic: Catch invalid ROM size
  kvm irqfd: support direct msimessage to irq translation
  fix steal time MSR vmsd callback to proper opaque type
  kvm: warn if num cpus is greater than num recommended
  cpu: Move cpu state syncs up into cpu_dump_state()
  exec: always use MADV_DONTFORK
