Sonic Zhang	064cc44e62	Blackfin: SMP: kgdb: flush core internal write buffer before flushinv ... KGDB single step in SMP kernel may hang forever in flushinv without a CSYNC ahead. This is because the core internal write buffers need to be flushed before invalidating the data cache to make sure the insn fetch is not out of sync.

Mike Frysinger	f99e8c1d0f	Blackfin: work around testset anomaly 05000477 ... Ironically, the atomic testset instruction cannot be interrupted else it will produce incorrect results. So disable interrupts to help it out. Signed-off-by: Mike Frysinger <vapier@gentoo.org>	2009-11-25 02:35:39 -05:00
Robin Getz	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).
