* [PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_semJes Sorensen2006-01-09
| | | | | | | | | | | | | This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different. Modified-by: Ingo Molnar <mingo@elte.hu> (finished the conversion) Signed-off-by: Jes Sorensen <jes@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* [PATCH] mutex subsystem, semaphore to mutex: XFSJes Sorensen2006-01-09
| | | | | | | | | | This patch switches XFS over to use the new mutex code directly as opposed to the previous workaround patch I posted earlier that avoided the namespace clash by forcing it back to semaphores. This falls in the 'works for me<tm>' category. Signed-off-by: Jes Sorensen <jes@trained-monkey.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

* [PATCH] mutex subsystem, add default include/asm-*/mutex.h filesArjan van de Ven2006-01-09
| | | | | | | | | | | | | 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.

* [PATCH] mutex subsystem, add asm-generic/mutex-[dec|xchg|null].h implementationsIngo Molnar2006-01-09
| | | | | | | | | | | | | | | | | | Add three (generic) mutex fastpath implementations. The mutex-xchg.h implementation is atomic_xchg() based, and should work fine on every architecture. The mutex-dec.h implementation is atomic_dec_return() based - this one too should work on every architecture, but might not perform the most optimally on architectures that have no atomic-dec/inc instructions. The mutex-null.h implementation forces all calls into the slowpath. This is used for mutex debugging, but it can also be used on platforms that do not want (or need) a fastpath at all.

| * V4L/DVB (3324): msp3400 audio handling bug fixes.Hans Verkuil2006-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Check capabilities for audio settings (volume, balance, bass, treble, loudness, mute) - added loudness support - added missing VIDEO_AUDIO_BALANCE flags for v4l1 compatibility - do not call msp_any_detect_stereo for non-autoselect chips to retrieve the current stereo setting: that will temporarily mute the sound. It is only needed when the stereo mode might be changed, and for autoselect msp processors that do not periodically need to update their stereo setting. - do not wake up the thread if the standard did not change. Prevents temporary audio drop-out if the standard is set to the same value. - fix confused stereo detect code where V4L2_TUNER_SUB_STEREO and V4L2_TUNER_MODE_STEREO values were used incorrectly. - stereo mode reporting was broken (v4l2 value used to index a string array expecting v4l1 mode values). - do not set dsp register 0x30 in the 3410d thread: that register does not exist for pre-'G' revision msp chips.
