This series forms the kvm host part of paravirtual spinlock based against kvm tree. Please refer https://lkml.org/lkml/2013/8/6/178 for kvm guest part of the series. Please note that: kvm uapi: Add KICK_CPU and PV_UNHALT definition to uapi is a common patch for both guest and host.

This series replaces the existing paravirtualized spinlock mechanism with a paravirtualized ticketlock mechanism. The series provides implementation for both Xen and KVM. Changes in V11: - use safe_halt in lock_spinning path to avoid potential problem in case of irq_handlers taking lock in slowpath (Gleb) - add a0 flag for the kick hypercall for future extension (Gleb) - add stubs for
