commit 71952bfcbe9187765cf4010b1479af86def4fb1f

    xen: arm: Enable 1:1 workaround by default
    I was just about to send out patches adding the 1:1 workaround to vexpress
    (the foundation model is a vexpress platfrom with DMA) and sunxi.
    That would have meant that all platforms now implement the quirk. Instead 
    just make it the default and remove the quirk.
    In the future this will likely be set based on the presence absence of an
    IOMMU, perhaps with additional overrides by the platform.
    This results in some dead code in domain_build for dealing with the non-1:1
    case. This is deliberate and is left in anticipation of IOMMU support in 
    PLATFORM_QUIRK_GIC_64K_STRIDE is renumbered as a side effect of this change.

    libxenctrl: Fix xc_interface_close() crash if it gets NULL as an argument
    xc_interface_close() crashes if it gets NULL as an argument. However,
    it just calls xc_interface_close_common() which is called by many
    others functions. It means that they are also vulnerable. So fix above
    mentioned issue by adding NULL check in xc_interface_close_common().
    This way we fix similar issue in other functions which calls
    xc_interface_close_common() too.

    xen: arm: TCR_EL1 is 64-bit on arm64
    Storing it in a 32-bit variable in struct arch_vcpu caused breakage over
    context switch.
    There were also several other places which stored this as the 32-bit value.
    Update them all.
    The "struct vcpu_guest_context" case needs special consideration. This 
    is in theory is exposed to guests, via the VCPUOP_initialise hypercall.
    However as discussed in
    http://lists.xen.org/archives/html/xen-devel/2013-10/msg00912.html this 
    really a guest visible interface since ARM uses PSCI for VCPU bringup
    (VCPUOP_initialise simply isn't available) The other users of this interface
    are the domctls, which are not a stable API. Therefore while fixing the 
    size also surround the struct in ifdefs to restrict the struct to the
    hypervisor and the tools only (omitting the extra complexity of renaming as 
    suggested in the referenced thread).
    NB TCR_EL1 on arm64 is known as TTBCR on arm32, hence the apparent naming

    arinc: add cpu-pool support to scheduler
    1.  Remove the restriction that dom0 must be in the schedule, since dom-0 
    not belong to the scheduler's pool.
    2.  Add a schedule entry for each of dom-0's vcpus as they are created.
    3.  Add code to deal with empty schedules in the do_schedule function.
    4.  Call the correct idle task for the pcpu on which the scheduling decision
    is being made in do_schedule.
    5.  Add code to prevent migration of a vcpu.
    6.  Implement a proper cpu_pick function, which prefers the current 
    7.  Add a scheduler lock to protect access to global variables from multiple
    These changes do not implement arinc653 multicore.  Since the schedule only
    supports 1 vcpu entry per slot, even if the vcpus of a domain are run on
    multiple pcpus, the scheduler will essentially serialize their execution.
