[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 0/10] Integrate msr.h
Hello,
This series of patches integrates msr.h header.
What it really does, is a series of steps to allow us
to get rid of duplicate code between i386 and x86_64 versions
With this done, achieving paravirt for x86_64 gets really easy,
just a couple of extra code.
The first patch was already sent a while ago, but was not yet pushed
to any tree , to my knowledge. So it is sent again. Also,
