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).

The protect_page() function was incorrectly setting up the hardware tables
based on possible access capabilities rather than the actual requested
values. This means we would grant more access to mmap-ed pages than we
should have. Once we fix this, we need to tweak the signal generated by
such accesses to aline ourselves with other ports. This allows the LTP
mmap0{5,6,7} cases to run properly.
