[PATCH 00/14] PV ticket locks without expanding spinlock
From: Jeremy Fitzhardinge <jeremy.fitzhardinge at citrix.com>
Hi all,
This is a revised version of the pvticket lock series.
The early part of the series is mostly unchanged: it converts the bulk
of the ticket lock code into C and makes the "small" and "large"
ticket code common. The only changes are the incorporation of various
review comments.

[PATCH 00/20] x86: ticket lock rewrite and paravirtualization
From: Jeremy Fitzhardinge <jeremy.fitzhardinge at citrix.com>
Hi all,
This series does two major things:
1. It converts the bulk of the implementation to C, and makes the
"small ticket" and "large ticket" code common. Only the actual
size-dependent asm instructions are specific to the ticket size.
The resulting generated asm is very similar to the current

[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
