[PATCH RFC V3 0/4] kvm : Paravirt-spinlock support for KVM guests
The 4-patch series to follow this email extends KVM-hypervisor and Linux guest
running on KVM-hypervisor to support pv-ticket spinlocks, based on Xen's implementation.
One hypercall is introduced in KVM hypervisor,that allows a vcpu to kick
another vcpu out of halt state.
The blocking of vcpu is done using halt() in (lock_spinning) slowpath.
