* atomic: Collapse all atomic_{set,clear}_mask definitionsPeter Zijlstra2015-07-271-10/+0
| | | | | | | | | | | Move the now generic definitions of atomic_{set,clear}_mask() into linux/atomic.h to avoid endless and pointless repetition. Also, provide an atomic_andnot() wrapper for those few archs that can implement that. Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* atomic: Provide atomic_{or,xor,and}Peter Zijlstra2015-07-271-2/+0
| | | | | | | | | | Implement atomic logic ops -- atomic_{or,xor,and}. These will replace the atomic_{set,clear}_mask functions that are available on some archs. Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* blackfin: Provide atomic_{or,xor,and}Peter Zijlstra2015-07-271-7/+21
| | | | | | | | | | | | Implement atomic logic ops -- atomic_{or,xor,and}. These will replace the atomic_{set,clear}_mask functions that are available on some archs. TODO: use inline asm or at least asm macros to collapse the lot. Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

* Blackfin: SMP: convert to common asm-generic/atomic.hMike Frysinger2011-10-251-94/+10
| | | | | | | Now that common code supports SMP systems, switch our SMP atomic logic over to it to avoid code duplication. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* atomic: cleanup asm-generic atomic*.h inclusionArun Sharma2011-07-261-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | After changing all consumers of atomics to include <linux/atomic.h>, we ran into some compile time errors due to this dependency chain: linux/atomic.h -> asm/atomic.h -> asm-generic/atomic-long.h where atomic-long.h could use funcs defined later in linux/atomic.h without a prototype. This patches moves the code that includes asm-generic/atomic*.h to linux/atomic.h. Archs that need <asm-generic/atomic64.h> need to select CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it unconditionally). Compile tested on i386 and x86_64 with allnoconfig.

* Blackfin: mass clean up of copyright/licensing infoRobin Getz2009-10-071-0/+6
| | | | | | | | | | | | | | | | | | 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).

* Blackfin: fix flag storage for irq funcsMike Frysinger2009-06-131-8/+8
| | | | | | | The IRQ functions take an "unsigned long" flags variable, not any other type, so fix the places where we use "int" or "long". Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* asm-generic: rename atomic.h to atomic-long.hArnd Bergmann2009-06-111-1/+1
| | | | | | | | | | | The existing asm-generic/atomic.h only defines the atomic_long type. This renames it to atomic-long.h so we have a place to add a truly generic atomic.h that can be used on all non-SMP systems.

* atomic_t: unify all arch definitionsMatthew Wilcox2009-01-061-3/+1
| | | | | | | | | | | | The atomic_t type cannot currently be used in some header files because it would create an include loop with asm/atomic.h.
