Subject: [PATCH V13 0/4] Paravirtualized ticket spinlocks for KVM host 


 This series forms the kvm host part of paravirtual spinlock
 based against kvm tree.

 Please refer to https://lkml.org/lkml/2013/8/9/265 for
 kvm guest and Xen, x86 part merged to -tip spinlocks.

 Please note that:
 kvm uapi: Add KICK_CPU and PV_UNHALT definition to uapi is a common patch
 for both guest and host.

 Changes since V12:
  fold the patch 3 into patch 2 for bisection. (Eric Northup)

Raghavendra K T (3):
  kvm uapi: Add KICK_CPU and PV_UNHALT definition to uapi
  kvm hypervisor: Simplify kvm_for_each_vcpu with
    kvm_irq_delivery_to_apic
  Documentation/kvm : Add documentation on Hypercalls and features used
    for PV spinlock

Srivatsa Vaddagiri (1):
  kvm hypervisor : Add a hypercall to KVM hypervisor to support
    pv-ticketlocks
