The following patches introduce the core infrastructure needed to paravirtualize the 32-bit x86 Linux kernel. This is done by moving virtualization sensitive insn's or code paths to a function table, paravirt_ops. This structure can be populated with hypervisor specific calls or native stubs and currently support running on bare metal, VMI, Xen, or Lhype. These patches apply to

Hi Andi, This series of patches updates paravirt_ops in various ways. Some of the changes are plain cleanups and improvements, and some add some interfaces necessary for Xen. The brief overview: add-MAINTAINERS.patch - obvious remove-CONFIG_DEBUG_PARAVIRT.patch - no longer needed paravirt-nop.patch - mark nop operations consistently paravirt-pte-accessors.patch - operations to pack/unpack

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. paravirt-nop.patch Clean up nop paravirt_ops functions, mainly to

Hi Andi, This patch series implements the Linux Xen guest in terms of the paravirt-ops interface. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual
