2012-03-23mm: fix testorder interaction between two kswapd patchesHugh Dickins
Adjusting cc715d99e529 "mm: vmscan: forcibly scan highmem if there are too many buffer_heads pinning highmem" for -stable reveals that it was slightly wrong once on top of fe2c2a106663 "vmscan: reclaim at order 0 when compaction is enabled", which specifically adds testorder for the zone_watermark_ok_safe() test.

2012-03-22security: optimize avc_audit() common pathLinus Torvalds
avc_audit() did a lot of jumping around and had a big stack frame, all for the uncommon case. Split up the uncommon case (which we really can't make go fast anyway) into its own slow function, and mark the conditional branches appropriately for the common likely case. This causes avc_audit() to no longer show up as one of the hottest functions on the branch profiles (the new "perf -b" thing), and makes the cycle profiles look really nice and dense too. The whole audit path is still annoyingly very much one of the biggest costs of name lookup, so these things are worth optimizing for. I wish we could just tell people to turn it off, but realistically we do need it: we just need to make sure that the overhead of the necessary evil is as low as possible.

Most of the code to support the new chips has already gone in, however this pull contains a few more pieces along with the final enables so the driver binds to the new Kepler cards. Its quite amazing that nouveau can support a GPU on its launch day even if its just unaccelerated modesetting, and I'd like to have support in the next kernel. In order to sweeten the deal, Ben has also requested nouveau destage and become ABI stable, the only change is the version number bump which he prepared userspace for quite a long time ago.

This contains a patch that is also in the fbdev tree, but it should be the same patch, it added an API for hot unplugging framebuffer devices, and I need that API for a new driver. It also contains some changes to the i2c tree which Jean has acked, and one change to moorestown platform stuff in x86. Highlights: - new drivers: UDL driver for USB displaylink devices, kms only, should support correct hotplug operations. - core: i2c speedups + better hotplug support, EDID overriding via firmware interface - allows user to load a firmware for a broken monitor/kvm from userspace, it even has documentation for it. - exynos: new HDMI audio + hdmi 1.4 + virtual output driver - gma500: code cleanup - radeon: cleanups, CS optimisations, streamout support and pageflip fix - nouveau: NVD9 displayport support + more reclocking work - i915: re-enabling GMBUS, finish gpu patch (might help hibernation who knows), missed irq fixes, stencil tiling fixes, interlaced support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB, semaphore fixes As well as the usual bunch of cleanups and fixes all over the place. I've got two things I'd like to merge a bit later: a) AMD support for all their new radeonhd 7000 series GPU and APUs. AMD dropped this a bit late due to insane internal review processes, (please AMD just follow Intel and let open source guys ship stuff early) however I don't want to penalise people who own this hardware (since its been on sale for 3-4 months and GPU hw doesn't exactly have a lifetime in years) and consign them to using closed drivers for longer than necessary. The changes are well contained and just plug into the driver new gpu functionality so they should be fairly regression proof. I just want to give them a bit of a run on the hw AMD kindly sent me. b) drm prime/dma-buf interface code. This is just infrastructure code to expose the dma-buf stuff to drm drivers and to userspace. I'm not planning on pushing any driver support in this cycle (except maybe exynos), but I'd like to get the infrastructure code in so for the next cycle I can start getting the driver support into the individual drivers. We have started driver support for i915, nouveau and udl along with I think exynos and omap in staging. However this code relies on the dma-buf tree being pulled into your tree first since it needs the latest interfaces from that tree. I'll push to get that tree sent asap.

2012-03-22Merge tag 'sound-3.4' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull updates of sound stuff from Takashi Iwai: "Here is the first big update chunk of sound stuff for 3.4-rc1. In the common sound infrastructure, there are a few changes for dynamic PCM support (used in ASoC) and a few clean-ups. Majority of changes are found, as usual, in HD-audio and ASoC. Some highlights of HD-audio changes: - All the long-standing static quirk codes for Realtek codec were finally removed by fixing and extending the Realtek auto-parser. - The mute-LED control is standardized over all HD-audio codec drivers using the extended vmaster hook. - The vmaster slave mixer elements are initialized to 0dB as default so that the user won't be annoyed by the silent output after updates, e.g. due to the additions of new elements. - Other many fix-ups for the misc HD-audio devices. In the ASoC side, this is a very active release, including a quite a few framework enhancements. Some highlights: - Support for widgets not associated with a CODEC, an important part of the dynamic PCM framework. - A library factoring out the common code shared by dmaengine based DMA drivers contributed by Lars-Peter Clausen. This will save a lot of code and make it much easier to deploy enhancements to dmaengine. - Support for binary controls, used for providing runtime configuration of algorithm coefficients. - A new DAPM widget type for regulator supplies allowing drivers for devices that can power down unused supplies while active to do without any per-driver code. - DAPM widgets for DAIs, initially giving a speed boost for playback startup and shutdown and also the basis for CODEC<->CODEC DAI link support. - Support for specifying the number of significant bits on audio interfaces, useful for allowing applications to know how much effort to put into generating data for a larger sample format. - Conversion of the FSI driver used on some SH processors to DMAEngine. - Conversion of EP93xx drivers to DMAEngine. - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics WM2200. - Move audmux driver from arc/arm to sound/soc - McBSP move from arch/ to sound/ and updates Also, a few small updates and fixes for other drivers like au88x0, ymfpci, USB 6fire, USB usx2yaudio are included." * tag 'sound-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (446 commits) ASoC: wm8994: Provide VMID mode control and fix default sequence ASoC: wm8994: Add missing break in resume ASoC: wm_hubs: Don't actively manage LINEOUT_VMID_BUF ASoC: pxa-ssp: atomically set stream active masks ASoC: fsl: p1022ds: tell the WM8776 codec driver that it's the master ASoC: Samsung: Added to support mono recording ALSA: hda - Fix build with CONFIG_PM=n ALSA: au88x0 - Avoid possible Oops at unbinding ALSA: usb-audio - Fix build error by consitification of rate list ASoC: core: Fix obscure leak of runtime array ALSA: pcm - Avoid GFP_ATOMIC in snd_pcm_link() ALSA: pcm: Constify the list in snd_pcm_hw_constraint_list ASoC: wm8996: Add 44.1kHz support ALSA: hda - Fix build of patch_sigmatel.c without CONFIG_SND_HDA_POWER_SAVE ASoC: mx27vis-aic32x4: Convert it to platform driver ALSA: hda - fix printing of high HDMI sample rates ALSA: ymfpci - Fix legacy registers on S3/S4 resume ALSA: control - Fixe a trailing white space error ALSA: hda - Add expose_enum_ctl flag to snd_hda_add_vmaster_hook() ALSA: hda - Add "Mute-LED Mode" enum control ...
