commit 9c102f994856d1de5a62644822d07a99318073cb

    Fix for a segmentation violation generated by the ARM64 "bt -[f|F]"
    options when analyzing the active tasks in vmcores generated by the
    kdump facility.  This bug is a regression that was introduced in
    crash-7.1.2 by commit 15a58e4070486efa2aa965bdd636626e62b65cc7, which
    was an enhancement of the ARM64 backtrace capability for active tasks
    in kdump vmcores.
