This patch converts the superblock-lock semaphore to a mutex, affecting lock_super()/unlock_super(). Tested on ext3 and XFS. Signed-off-by:Ingo Molnar <mingo@elte.hu>

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:

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:

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.

add the ARM version of mutex.h, which is optimized in assembly for ARMv6, and uses the xchg implementation on pre-ARMv6. Signed-off-by: -

Ingo Molnar authored
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. Signed-off-by:

- 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.

- Saa7134-core.c saa7134_irq(): Separate GPIO16 and GPIO18 handling. Call IR-remote-GPIO handler only if the GPIO IRQ is "owned" by it. Added infrastructure to branch out to a future I2C-IR IRQ handler. saa7134-core.c saa7134_hwinit2(): Enable only the one GPIO pin and edge to trigger an IRQ that is wired as keyup/keydown mask. IRQ will only be generated for an actual key-down event. saa7134-input.c flyvideo_codes[]: Replace numpad keys with normal ones. Put meaning to mystery keys. Change some key definitions to have their functions match their labels better. Fix typos. saa7134-input.c flydvb_codes[]: Added new table for the larger remote that comes with the LifeView FlyDVB series. saa7134-input.c build_key(): In IRQ mode, signal key-down and then key-up straight in one go.

This is a major update to the cyblafb framebuffer driver. Most of the stuff has been tested in the mm tree. Main advantages: ============ - vxres > xres support - ywrap and xpan support - much faster for almost all modes (e.g. 1280x1024-16bpp draws more than 41 full screens of text instead of about 25 full screens of text per second on authors Epia 5000) - module init/exit code fixed - bugs triggered by console rotation fixed - lots of minor improvements - startup modes suitable for high performance scrolling in all directions This diff also contains a lot of white space fixes. No side effects are possible, only one single graphics core is affected. Signed-off-by:Knut Petersen <Knut_Petersen@t-online.de> Signed-off-by:
