[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,

[PATCH 1/2] lguest: handle dodgy/non-existent TSC. Host code.
Lguest currently requires a TSC, which breaks older machines and Matt
Mackall who boots the host with "notsc". In addition, there is no
good solution to changing TSC speeds (informing all the guests about
the TSC impending change before it happens would be a great deal of
code and have issues with disobedient guests).
This patch makes the host determine if the TSC is both constant and

[patch 00/20] paravirt_ops updates
Hi Andi,
Here's a repost of the paravirt_ops update series I posted the other day.
Since then, I found a few potential bugs with patching clobbering,
cleaned up and documented paravirt.h and the patching machinery.
Overview:
add-MAINTAINERS.patch
obvious
remove-CONFIG_DEBUG_PARAVIRT.patch
No longer meaningful or needed.
