In order to safely work around anomaly 05000491, we have to execute IFLUSH
from L1 instruction sram. The trouble with multi-core systems is that all
L1 sram is visible only to the active core. So we can't just place the
functions into L1 and call it directly. We need to setup a jump table and
place the entry point in external memory. This will call the right func
based on the active core.In the process, convert from the manual relocation of a small bit of code
into Core B's L1 to the more general framework we already have in place
for loading arbitrary pieces of code into L1.Signed-off-by: Sonic Zhang

This functions are implicitly called by core functions like cpu_relax(),
and since those functions may be called early on before common code has
initialized the per-cpu data area, we need to tweak the stats gathering.
Now the statistics are maintained in common bss which makes these funcs
safe to use as soon as the C runtime env is setup.Signed-off-by: Graf Yang

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 rightIt also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).Signed-off-by: Robin Getz
