commit 701190abb3d5873cf77349b3d90bd11ded74871a

    xen/arm: Set correct per-cpu cpu_core_mask
    
    In the common sysctl command XEN_SYSCTL_physinfo, the value of
    cores_per_socket is calculated based on the cpu_core_mask of CPU0.
    Currently on Arm this is a fixed value 1 (can be checked via xl info),
    which is not correct. This is because during the Arm CPU online
    process at boot time, setup_cpu_sibling_map() only sets the per-cpu
    cpu_core_mask for itself.
    
    cores_per_socket refers to the number of cores that belong to the same
    socket (NUMA node). Currently Xen on Arm does not support physical
    CPU hotplug and NUMA, also we assume there is no multithread. Therefore
    cores_per_socket means all possible CPUs detected from the device
    tree. Setting the per-cpu cpu_core_mask in setup_cpu_sibling_map()
    accordingly. Modify the in-code comment which seems to be outdated. Add
    a warning to users if Xen is running on processors with multithread
    support.
