[Qemu-devel] [PATCH v3 0/5] KVM: Hyper-V VMBus hypercalls

[Andrey Smetanin <asmetanin@virtuozzo.com>]

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
