Merge remote-tracking branch 'qemu-kvm/uq/master' into staging
# By Alexey Kardashevskiy (3) and others
# Via Paolo Bonzini
* 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
