ms/drivers/hv: Move VMBus hypercall codes into Hyper-V UAPI header
Series description:
KVM: Hyper-V VMBus hypercalls
The patch implements userspace exit 'KVM_EXIT_HYPERV'
for Hyper-V VMBus hypercalls(postmsg, signalevent)
to handle these hypercalls by QEMU.
Changes v3:
* use vcpu->arch.complete_userspace_io to setup hypercall
result
* rebase for 'next-20160211'
Changes v2:
* use KVM_EXIT_HYPERV for hypercalls
https://jira.sw.ru/browse/PSBM-44419
Andrey Smetanin (5):
ms/kvm/x86: Rename Hyper-V long spin wait hypercall
ms/drivers/hv: Move VMBus hypercall codes into Hyper-V UAPI header
ms/kvm/x86: Pass return code of kvm_emulate_hypercall
ms/kvm/x86: Reject Hyper-V hypercall continuation
ms/kvm/x86: Hyper-V VMBus hypercall userspace exit

[Do not rename the constant at the same time as moving it, as that
would cause semantic conflicts with the Hyper-V tree. - Paolo]
