[PATCH 9/9] kvm/x86: Hyper-V kvm exit
...dicates that the VCPU exits into userspace to process some tasks

The documentation should include the definition of the struct and the
definition of the subtypes (currently KVM_EXIT_HYPERV_SYNIC only).
Documentation for KVM_CAP_HYPERV_SINIC and KVM_IRQ_ROUTING_HV_SINT is
missing, too.
Finally, it would be better to have unit tests in kvm-unit-tests.
Either this or QEMU support is a requirement for merging, and the unit
tests are probably easier.

[PATCH v2 0/9] Hyper-V synthetic interrupt controller
This patchset implements the KVM part of the synthetic interrupt
controller (SynIC) which is a building block of the Hyper-V
paravirtualized device bus (vmbus).
SynIC is a lapic extension, which is controlled via MSRs and maintains
for each vCPU
- 16 synthetic interrupt "lines" (SINT's); each can be configured to
trigger a specific interrupt vector optionally with auto-EOI

[PATCH 0/7] Hyper-V Synthetic interrupt controller
Hyper-V SynIC (synthetic interrupt controller) device
implementation.
The implementation contains:
* msr's support
* irq routing setup
* irq injection
* irq ack callback registration
* event/message pages changes tracking at Hyper-V exit
* Hyper-V test device to test SynIC by kvm-unit-tests
Andrey Smetanin (7):
