2009-12-15Blackfin: push down asm/ includes and out of bfin-global.hMike Frysinger
Avoid including unnecessary headers all the time as well as circular includes with core requirements. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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).

2009-06-22Blackfin: unify memory region checks between kgdb and trapsMike Frysinger
The kgdb (in multiple places) and traps code developed pretty much identical checks for how to access different regions of the Blackfin memory map, but each wasn't 100%, so unify them to avoid duplication, bitrot, and bugs with edge cases. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-12Blackfin: push access_ok() L1 attribute downMike Frysinger
There is no need for the L1 attribute to be on the prototype of the access_ok() function as all consumers of the function do not care where it lives -- they'll always use pcrel calls to get to it. This prevents pointless recompiles of most of the system when this config option changes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-12Blackfin: punt duplicated search_exception_table() prototypeMike Frysinger
The common code already has a prototype for this function and we don't use it anywhere in the Blackfin code, so punt it from the Blackfin headers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-12Blackfin: add missing access_ok() checks to user functionsRobin Getz
The core string/clear user functions weren't checking the user pointers which caused kernel crashes with some bad programs and tests (like LTP). Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-01-07Blackfin arch: add __must_check markings to our user functions like other archesMike Frysinger
