From: Raghavendra K T <address@hidden>

Three patch series following this, extends KVM-hypervisor
and Linux guest running on KVM-hypervisor to support pv-ticket spinlocks.

PV ticket spinlock helps to solve Lock Holder Preemption problem discussed in

When spinlock is contended,a guest vcpu relinqueshes cpu by halt().
Correspondingly, One hypercall is introduced in KVM hypervisor,that allows
a vcpu to kick the halted vcpu to continue with execution.

The series will : 
- Update qemu with latest linux header files (to 3.2.0-rc1).
- Enable KICK_VCPU capability in kvm/i386.

Raghavendra K T(3):
  Sync the linux headers to 3.2.0-rc1
  Sync the linux headers to patched linux kernel with 
        KICK_VCPU capability.
  Add KICK_VCPU support in i386 target

The corresponding kernel patch is available in the thread
