[PATCH RFC V6 0/5] kvm : Paravirt-spinlock support for KVM guests
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
