[PATCH V13 0/4] Paravirtualized ticket spinlocks for KVM host
This series forms the kvm host part of paravirtual spinlock based against kvm tree. Please refer to https://lkml.org/lkml/2013/8/9/265 for kvm guest and Xen, x86 part merged to -tip spinlocks. Please note that: kvm uapi: Add KICK_CPU and PV_UNHALT definition to uapi is a common patch for both guest and host. Changes since V12: fold the patch 3 into patch 2 for bisection. (Eric Northup)

[PATCH RFC V6 0/5] kvm : Paravirt-spinlock support for KVM guests
...patches are targeted for 3.5 window ] Changes in V6: - Rebased to 3.4-rc3 - Removed debugfs changes patch which should now be in Xen/linux-next. (https://lkml.org/lkml/2012/3/30/687) - Removed PV_UNHALT_MSR since currently we don't need guest communication, and made pv_unhalt folded to GET_MP_STATE (Marcello, Avi[long back]) - Take jumplabel changes from Ingo/Jason into use (static_key_slow_inc usage) - Added inline to spinlock_init in non PARAVIRT case - Move arch specific code to arch/x86 and add stubs to other archs (Marcello) - Added more comments on pv_unhalt usage etc (Marcello) Change...

[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. The V2 change discussion was in:
