Hi Ingo, Please pull a few more cpus4096 changes. Most are fairly lightweight with the biggest change being to use cpumask_var_t's for the domain and pending_mask cpumask's in irq_desc. It also deals with this cpu_evtchn_mask bss space bump: 65536 +2031616 2097152 +3100% cpu_evtchn_mask(.bss) Everything merges into tip/master cleanly. Thanks! Mike The following changes since commit 36c401a44abcc389a00f9cd14892c9cf9bf0780d: Ingo Molnar (1): [IA64] fix typo in cpumask_of_pcibus() are available in th...

Hi Ingo, Here''s the chunk of patches to add Xen Dom0 support (it''s probably worth creating a new xen/dom0 topic branch for it). A dom0 Xen domain is basically the same as a normal domU domain, but it has extra privileges to directly access hardware. There are two issues to deal with: - translating to and from the domain''s pseudo-physical addresses and real machine

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

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 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
