linux.git/include/asm-ia64/mutex.h, branch master Linux kernel source tree [IA64] Move include/asm-ia64 to arch/ia64/include/asm 2008-08-01T17:21:21+00:00 Tony Luck tony.luck@intel.com 2008-08-01T17:13:32+00:00 7f30491ccd28627742e37899453ae20e3da8e18f After moving the the include files there were a few clean-ups: 1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h> 2) Some comments alerted maintainers to look at various header files to make matching updates if certain code were to be changed. Updated these comments to use the new include paths. 3) Some header files mentioned their own names in initial comments. Just deleted these self references.

[IA64] fix bug in ia64 __mutex_fastpath_trylock 2006-04-08T05:39:49+00:00 Chen, Kenneth W kenneth.w.chen@intel.com 2006-04-08T00:12:54+00:00 cfab9d0e1da8e08a39759d0fc3bf5e40f0ac2d55 The parenthesis around "likely" used in ia64 __mutex_fastpath_trylock is incorrect, and it leads to broken mutex_trylock. Here is the patch that fixed the bug. I removed the likely altogether because there is no branch and gcc does a reasonable job at predicating the return value.

[IA64] implement ia64 specific mutex primitives 2006-01-26T21:10:19+00:00 Chen, Kenneth W kenneth.w.chen@intel.com 2006-01-12T01:11:09+00:00 a454c2f3d1fd1cab7073b53c6c14d6d4b61f4e09 Implement ia64 optimized mutex primitives. It properly uses acquire/release memory ordering semantics in lock/unlock path. 2nd version making them all static inline functions.

[PATCH] mutex subsystem, add default include/asm-*/mutex.h files 2006-01-09T23:59:19+00:00 Arjan van de Ven arjan@infradead.org 2006-01-09T23:59:19+00:00 2acbb8c657af86b2fa5b185f1d7048385e310585 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. Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
