What does this patch fix, aside from being a bit cleaner?
If it built before, without having a task_struct declaration, I think
that means that the elf_core_copy_fpregs was never used. The
task_struct * in the declaration would become a private task_struct,
known only to the declaration. If the implementation or callers have
the regular task_struct, it will be a different one, and the
prototypes will conflict due to the different types of the first
parameter.
