[PATCH 0/25][V3] pvops_64 last round (hopefully)
This is hopefully the last iteration of the pvops64 patch.
>From the last version, we have only one change, which is include/asm-x86_64/processor.h: There were still one survivor in raw asm.
Also, git screwed me up for some reason, and the 25th patch was missing the new files, paravirt.{c,h}. (although I do remember having git-add'ed it, but who knows...)
Andrew, could you please push it

[PATCH 1/3] Paravirtualization: Kernel Ring Cleanups
Hi all,
I've been looking at finding common ground between the VMI, Xen and
other paravirtualization approaches, and after some discussion, we're
getting somewhere.
These first two patches are the fundamentals, stolen mainly from the
VMI patches: removing assumptions about the kernel running in ring 0,
and macro-izing all the obvious para-virtualize-needing insns. The
third patch is
