2010-03-09Blackfin: rewrite resync_core_{i,d}cache() SMP logic to avoid per_cpu dataGraf Yang
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.

2009-10-07Blackfin: mass clean up of copyright/licensing infoRobin Getz
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).
