[PATCH 0/15] adjust pvops to accomodate its x86_64 variant
Hi folks,
With this series, the bulk of the work of pvops64 is done.
Here, I integrate most of the paravirt.c and paravirt.h files, making
them applicable to both architectures.
CONFIG_PARAVIRT is _not_ present yet. Basically, this code is missing page
table integration (patches currently being worked on by Jeremy).
Enjoy

[PATCH] paravirt: remove paravirt ops pmd_update_defer and pte_update_defer
pte_update_defer can be removed as it is always set to the same
function as pte_update. So any usage of pte_update_defer() can be
replaced by pte_update().
pmd_update_defer is always set to paravirt_nop, so it can just be
nuked.

[PATCH 00/10] x86/paravirt: several cleanups
This series removes some no longer needed stuff from paravirt
infrastructure and puts large quantities of paravirt ops under a new
config option PARAVIRT_XXL which is selected by XEN_PV only.
A pvops kernel without XEN_PV being configured is about 2.5% smaller
with this series applied.
