    Arm64: make setup_virt_paging()'s pa_range_info[] static
    
    While not as inefficient as it would be on x86 (due to suitable constant
    loading and register pair storing instructions being available to fill
    some of the fields), having the compiler construct an array of constants
    on the stack still looks odd to me.
