[PATCH v3 0/2] kvm: x86: hyperv: guest->host event signaling via eventfd

[Roman Kagan <rkagan@virtuozzo.com>]

Make it possible for guests using Hyper-V emulation to do guest->host
notification via EVENT_SIGNAL hypercall without a user exit.

v2 -> v3:
 - expand docs on allowed values and return codes
 - fix uninitialized return
 - style fixes

v1 -> v2:
 - make data types consistent
 - get by without the recently dropped struct hv_input_signal_event
 - fix subject prefixes

Roman Kagan (2):
  kvm: x86: factor out kvm.arch.hyperv (de)init
  kvm: x86: hyperv: guest->host event signaling via eventfd
