[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):
standard-headers/x86: add Hyper-V SynIC constants

[PATCH 0/5] paravirt clock source patches, #5
paravirt clock source patches, next round.
There is now a pvclock-abi.h file with the structs and some longish
comments in it and everybody is switched over to use the stuff in
there.
Some minor tweaks after super-fast review by Jeremy.
The queue is on top of the kvm git tree. The first two patches should
have no kvm dependencies and should apply to linus tree just fine.

[RFC PATCH v6 00/92] VM introspection
The KVM introspection subsystem provides a facility for applications running
on the host or in a separate VM, to control the execution of other VM-s
(pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.),
alter the page access bits in the shadow page tables (only for the hardware
backed ones, eg. Intel's EPT) and receive notifications when events of
interest have taken place
