Messages in this thread Patch in this message | | | Date | Thu, 5 Jan 2006 16:37:43 +0100 | From | Ingo Molnar <> | Subject | [patch 07/21] mutex subsystem, add default include/asm-*/mutex.h files |
| |
From: Arjan van de Ven <arjan@infradead.org>
add the per-arch mutex.h files for the remaining architectures.
We default to asm-generic/mutex-dec.h, because that performs quite well on most arches. Arches that do not have atomic decrement/increment instructions should switch to mutex-xchg.h instead. Arches can also provide their own implementation for the mutex fastpath primitives.
