[PATCH 0/6] x86: reduce paravirtualized spinlock overhead
Paravirtualized spinlocks produce some overhead even if the kernel is
running on bare metal. The main reason are the more complex locking
and unlocking functions. Especially unlocking is no longer just one
instruction but so complex that it is no longer inlined.
This patch series addresses this issue by adding two more pvops
functions to reduce the size of the inlined spinlock functions. When

[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
