2008-10-16x86: rename iommu_num_pages function to iommu_nr_pagesJoerg Roedel
This series of patches re-introduces the iommu_num_pages function so that it can be used by each architecture specific IOMMU implementations. The series also changes IOMMU implementations for X86, Alpha, PowerPC and UltraSparc. The other implementations are not yet changed because the modifications required are not obvious and I can't test them on real hardware.

2008-10-15KVM: Reduce stack usage in kvm_pv_mmu_op()Dave Hansen
We're in a hot path. We can't use kmalloc() because it might impact performance. So, we just stick the buffer that we need into the kvm_vcpu_arch structure. This is used very often, so it is not really a waste. We also have to move the buffer structure's definition to the arch-specific x86 kvm header.

2008-10-15KVM: pci device assignmentBen-Ami Yassour
Based on a patch from: Amit Shah <amit.shah@qumranet.com> This patch adds support for handling PCI devices that are assigned to the guest. The device to be assigned to the guest is registered in the host kernel and interrupt delivery is handled. If a device is already assigned, or the device driver for it is still loaded on the host, the device assignment is failed by conveying a -EBUSY reply to the userspace. Devices that share their interrupt line are not supported at the moment. By itself, this patch will not make devices work within the guest. The VT-d extension is required to enable the device to perform DMA. Another alternative is PVDMA.

2008-10-15KVM: VMX: Reinject real mode exceptionJan Kiszka
As we execute real mode guests in VM86 mode, exception have to be reinjected appropriately when the guest triggered them. For this purpose the patch adopts the real-mode injection pattern used in vmx_inject_irq to vmx_queue_exception, additionally taking care that the IP is set correctly for #BP exceptions. Furthermore it extends handle_rmode_exception to reinject all those exceptions that can be raised in real mode. This fixes the execution of himem.exe from FreeDOS and also makes its debug.com work properly. Note that guest debugging in real mode is broken now. This has to be fixed by the scheduled debugging infrastructure rework (will be done once base patches for QEMU have been accepted).

2008-10-15KVM: VMX: Move nmi injection failure processing to vm exit pathAvi Kivity
Instead of processing nmi injection failure in the vm entry path, move it to the vm exit path (vm_complete_interrupts()).

2008-10-15KVM: Move KVM TRACE DEFINITIONS to common headerHollis Blanchard

2008-10-13tty: Add termioxAlan Cox
We need a way to describe the various additional modes and flow control features that random weird hardware shows up and software such as wine wants to emulate as Windows supports them. TCGETX/TCSETX and the termiox ioctl are a SYS5 extension that we might as well adopt. This patches adds the structures and the basic ioctl interfaces when the TCGETX etc defines are added for an architecture. Drivers wishing to use this stuff need to add new methods.

They define a TIOCSERSETRS485 (ioctl.h), and the data structure (rs485.h) with allows to specify timings. Sounds just like what we want ?" and he's right: sort of. Rework the structure to use flag bits and make the time delay a fixed sized field so we don't get 32/64bit problems. Add the ioctls to x86 so that people know what to add to their platform of choice.

2008-10-13x86: move prefill_possible_map calling early, fix, V2Chuck Ebbert
Commit 4a701737 ("x86: move prefill_possible_map calling early, fix") is the wrong fix: prefill_possible_map() needs to be available even when CONFIG_HOTPLUG_CPU is not set. A followon patch will do that. Fix this correctly by making prefill_possible_map() available even when CONFIG_HOTPLUG_CPU is not set. The function is needed so that the number of possible CPUs can be determined. Tested on uniprocessor machine with CPU hotplug disabled.
