55ccf3fe3f 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.

2c1657c29f Blackfin: SMP: relocate blackfin_core_id() definition 
Since we're breaking apart some inter-header dependencies to avoid more
circular loops, move the blackfin_core_id() definition to the func that
it is based upon.

96f1050d3d Blackfin: mass clean up of copyright/licensing info 
Bill Gatliff & David Brownell pointed out we were missing some
copyrights, and licensing terms in some of the files in
./arch/blackfin, so this fixes things, and cleans them up.

It also removes:
 - verbose GPL text(refer to the top level ./COPYING file)
 - file names (you are looking at the file)
 - bug url (it's in the ./MAINTAINERS file)
 - "or later" on GPL-2, when we did not have that right

It also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).

10a5ecd03f Blackfin: update handling of anomaly 364 (wrong rev id in BF527-0.1) 
This anomaly only applies to the BF527-0.1, not the BF526-0.1, and not any
other revision of the BF527.  So make sure we don't go returning 0xffff
for other cases.
