Hey Jeremy, Please pull from devel/pat (based off your xen/dom0/core tree) which has one patch: Konrad Rzeszutek Wilk (1): xen/pat: make pte_flags(x) a pvops function. which is neccessary for the drivers/gpu/drm/radeon driver to work properly with AGP based cards (which look to be the only ones that try to set WC on pages). Also please pull from devel/kms.fixes-05 (based off your

This series removes some no longer needed stuff from paravirt infrastructure and puts large quantities of paravirt ops under a new config option PARAVIRT_XXL which is selected by XEN_PV only. A pvops kernel without XEN_PV being configured is about 2.5% smaller with this series applied. tip commit 5800dc5c19f34e6e03b5adab1282535cb102fafd ("x86/paravirt: Fix spectre-v2 mitigations for

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-rc7 + your patches + the last batch of pv_ops patches I posted. This patch generally restricts itself to Xen-specific parts of the tree, though it does make a few small changes elsewhere. These patches include: - some helper routines for allocating address space and walking pagetables - Xen

Today paravirtualization is a all-or-nothing game: either a kernel is compiled with no paravirtualization support at all, or it is supporting paravirtualized environments like Xen pv-guests or lguest additionally to some paravirtualized tuning for KVM, Hyperv, VMWare or Xen HVM-guests. As support of pv-guests requires quite intrusive pv-hooks (e.g. all access functions to page table entries,

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 block

Hi, This is the Xen implementation for the paravirt_ops interface. The series is based on 2.6.22-rc1-mm1, and I think its ready to be cooked in -mm with a view to being merged in 2.6.23. The first part of the series is some small changes to the core kernel. Apart from the new code added in "Allocate and free vmalloc areas" (posted many times before), they are simply a few one-liners
