fork: move the real prepare_to_copy() users to arch_dup_task_struct()
...
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.

C6X: fix KSTK_EIP and KSTK_ESP macros
...
There was a latent typo in the C6X KSTK_EIP and KSTK_ESP macros which
caused a problem with a new patch which used them. The broken definitions
were of the form:
#define KSTK_FOO(tsk) (task_pt_regs(task)->foo)
Note the use of task vs tsk. This actually worked before because the
only place in the kernel which used these macros passed in a local
pointer named task.
