    Pull KVM fixes from Paolo Bonzini:
    "On the x86 side, there are some optimizations and documentation
    updates. The big ARM/KVM change for 3.11, support for AArch64, will
    come through Catalin Marinas's tree. s390 and PPC have misc cleanups
    and bugfixes"

  • 5ae7f87a5   ARM: KVM: Allow host virt timer irq to be different from guest timer virt irq ... Browse Code »

    The arch_timer irq numbers (or PPI numbers) are implementation dependent,
    so the host virtual timer irq number can be different from guest virtual
    timer irq number.

    This patch ensures that host virtual timer irq number is read from DTB and
    guest virtual timer irq is determined based on vcpu target type.

  • 7275acdfe   ARM: KVM: move GIC/timer code to a common location ... Browse Code »

    As KVM/arm64 is looming on the horizon, it makes sense to move some
    of the common code to a single location in order to reduce duplication.

    The code could live anywhere. Actually, most of KVM is already built
    with a bunch of ugly ../../.. hacks in the various Makefiles, so we're
    not exactly talking about style here. But maybe it is time to start
    moving into a less ugly direction.

    The include files must be in a "public" location, as they are accessed
    from non-KVM files (arch/arm/kernel/asm-offsets.c).

    For this purpose, introduce two new locations:
    - virt/kvm/arm/ : x86 and ia64 already share the ioapic code in
    virt/kvm, so this could be seen as a (very ugly) precedent.
    - include/kvm/ : there is already an include/xen, and while the
    intent is slightly different, this seems as good a location as
    any

    Eventually, we should probably have independant Makefiles at every
    levels (just like everywhere else in the kernel), but this is just
    the first step.
