[PATCH 1/3] Paravirtualization: Kernel Ring Cleanups
Hi all,
I've been looking at finding common ground between the VMI, Xen and

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
