The 5-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. Note: 1) patch is based on 3.4-rc3 + ticketlock

This series replaces the existing paravirtualized spinlock mechanism with a paravirtualized ticketlock mechanism. The series provides implementation for both Xen and KVM.(targeted for 3.5 window) Note: This needs debugfs changes patch that should be in Xen / linux-next https://lkml.org/lkml/2012/3/30/687 Changes in V8: - Reabsed patches to 3.4-rc4 - Combined the KVM changes with ticketlock
