[PATCH V12 0/5] Paravirtualized ticket spinlocks for KVM host
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.

[PATCH V12 0/14] Paravirtualized ticket spinlocks
This series replaces the existing paravirtualized spinlock mechanism
with a paravirtualized ticketlock mechanism. The series provides
implementation for both Xen and KVM.
The current set of patches are for Xen/x86 spinlock/KVM guest side, to be included
against -tip.
I 'll be sending a separate patchset for KVM host based on kvm tree.
Please note I have added the below performance result

[PATCH RFC V10 0/18] Paravirtualized ticket spinlocks
This series replaces the existing paravirtualized spinlock mechanism
with a paravirtualized ticketlock mechanism. The series provides
implementation for both Xen and KVM.
Changes in V10:
Addressed Konrad's review comments:
- Added break in patch 5 since now we know exact cpu to wakeup
- Dropped patch 12 and Konrad needs to revert two patches to enable xen on hvm
