    fork: move the real prepare_to_copy() users to arch_dup_task_struct() · 55ccf3fe
    Suresh Siddha authored
    Historical prepare_to_copy() is mostly a no-op, duplicated for majority of
    the architectures and the rest following the x86 model of flushing the extended
    register state like fpu there.
    
    Remove it and use the arch_dup_task_struct() instead.
