(Andrew, please sit these in the -mm tree for cooking) Create a paravirt.h header for (almost) all the critical operations which need to be replaced with hypervisor calls. For the moment, this simply includes no_paravirt.h, where all the native implementations now live.

...at the top 64 bits are unchanged (and ASSERT()s the fact) and performs a regular write on the lower 64 bits. * _set_gate_lower This is functionally equivalent to the already present _set_gate(), except it uses _write_gate_lower rather than updating both 64bit values. * _update_gate_addr_lower This is designed to update an IDT entry handler only, without altering any other settings in the entry. It also uses _write_gate_lower. The IDT entry helpers are required because: * Is it unsafe to attempt a disable/update/re-enable cycle on the NMI or MCE IDT entries. *...

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

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths

Hi. This patchset implements ia64/pv_ops support which is the framework for virtualization support. Changes from take 5 are rebased to Linux 2.6.26-rc3, bug fix ivt.S paravirtualization and multi entry point support. I believe these patches can be applied to the linux ia64 repository. On x86 various ways to support virtualization were proposed, and eventually pv_ops won. So on ia64 the pv_ops
