2012-05-26Merge tag 'cleanup-initcall' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull sweeping late_initcall cleanup for arm-soc from Olof Johansson: "This is a patch series from Shawn Guo that moves from individual late_initcalls() to using a member in the machine structure to invoke a platform's late initcalls. This cleanup is a step in the move towards multiplatform kernels since it would reduce the need to check for compatible platforms in each and every initcall." Fix up trivial conflicts in arch/arm/mach-{exynos/mach-universal_c210.c, imx/mach-cpuimx51.c, omap2/board-generic.c} due to changes nearby (and, in the case of cpuimx51.c the board support being deleted) * tag 'cleanup-initcall' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: ux500: use machine specific hook for late init ARM: tegra: use machine specific hook for late init ARM: shmobile: use machine specific hook for late init ARM: sa1100: use machine specific hook for late init ARM: s3c64xx: use machine specific hook for late init ARM: prima2: use machine specific hook for late init ARM: pnx4008: use machine specific hook for late init ARM: omap2: use machine specific hook for late init ARM: omap1: use machine specific hook for late init ARM: msm: use machine specific hook for late init ARM: imx: use machine specific hook for late init ARM: exynos: use machine specific hook for late init ARM: ep93xx: use machine specific hook for late init ARM: davinci: use machine specific hook for late init ARM: provide a late_initcall hook for platform initialization

Pull arm-soc: soc specific changes (part 2) from Olof Johansson: "This adds support for the spear13xx platform, which has first been under review a long time ago and finally been completed after generic spear work has gone into the clock, dt and pinctrl branches. Also a number of updates for the samsung socs are part of this branch." Fix up trivial conflicts in drivers/gpio/gpio-samsung.c that look much worse than they are: the exonys5 init code was refactored in commit fd454997d687 ("gpio: samsung: refactor gpiolib init for exynos4/5"), and then commit f10590c9836c ("ARM: EXYNOS: add GPC4 bank instance") added a new gpio chip define and did tiny updates to the init code. So the conflict diff looks like hell, but it's actually a fairly simple change. * tag 'soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (34 commits) ARM: exynos: fix building with CONFIG_OF disabled ARM: EXYNOS: Add AUXDATA for i2c controllers ARM: dts: Update device tree source files for EXYNOS5250 ARM: EXYNOS: Add device tree support for interrupt combiner ARM: EXYNOS: Add irq_domain support for interrupt combiner ARM: EXYNOS: Remove a new bus_type instance for EXYNOS5 ARM: EXYNOS: update irqs for EXYNOS5250 SoC ARM: EXYNOS: Add pre-divider and fout mux clocks for bpll and mpll ARM: EXYNOS: add GPC4 bank instance ARM: EXYNOS: Redefine IRQ_MCT_L0,1 definition ARM: EXYNOS: Modify the GIC physical address for static io-mapping ARM: EXYNOS: Add watchdog timer clock instance pinctrl: SPEAr1310: Fix pin numbers for clcd_high_res SPEAr: Update MAINTAINERS and Documentation SPEAr13xx: Add defconfig SPEAr13xx: Add compilation support SPEAr13xx: Add dts and dtsi files pinctrl: Add SPEAr13xx pinctrl drivers pinctrl: SPEAr: Create macro for declaring GPIO PINS SPEAr13xx: Add common clock framework support ...

2012-05-25Merge branch 'for-linus' of ↵Linus Torvalds
git://git.linaro.org/people/mszyprowski/linux-dma-mapping Pull CMA and ARM DMA-mapping updates from Marek Szyprowski: "These patches contain two major updates for DMA mapping subsystem (mainly for ARM architecture). First one is Contiguous Memory Allocator (CMA) which makes it possible for device drivers to allocate big contiguous chunks of memory after the system has booted. The main difference from the similar frameworks is the fact that CMA allows to transparently reuse the memory region reserved for the big chunk allocation as a system memory, so no memory is wasted when no big chunk is allocated. Once the alloc request is issued, the framework migrates system pages to create space for the required big chunk of physically contiguous memory. For more information one can refer to nice LWN articles: - 'A reworked contiguous memory allocator': http://lwn.net/Articles/447405/ - 'CMA and ARM': http://lwn.net/Articles/450286/ - 'A deep dive into CMA': http://lwn.net/Articles/486301/ - and the following thread with the patches and links to all previous versions: https://lkml.org/lkml/2012/4/3/204 The main client for this new framework is ARM DMA-mapping subsystem. The second part provides a complete redesign in ARM DMA-mapping subsystem. The core implementation has been changed to use common struct dma_map_ops based infrastructure with the recent updates for new dma attributes merged in v3.4-rc2. This allows to use more than one implementation of dma-mapping calls and change/select them on the struct device basis. The first client of this new infractructure is dmabounce implementation which has been completely cut out of the core, common code. The last patch of this redesign update introduces a new, experimental implementation of dma-mapping calls on top of generic IOMMU framework. This lets ARM sub-platform to transparently use IOMMU for DMA-mapping calls if one provides required IOMMU hardware. For more information please refer to the following thread: http://www.spinics.net/lists/arm-kernel/msg175729.html The last patch merges changes from both updates and provides a resolution for the conflicts which cannot be avoided when patches have been applied on the same files (mainly arch/arm/mm/dma-mapping.c)."

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull user namespace enhancements from Eric Biederman: "This is a course correction for the user namespace, so that we can reach an inexpensive, maintainable, and reasonably complete implementation. Highlights: - Config guards make it impossible to enable the user namespace and code that has not been converted to be user namespace safe. - Use of the new kuid_t type ensures the if you somehow get past the config guards the kernel will encounter type errors if you enable user namespaces and attempt to compile in code whose permission checks have not been updated to be user namespace safe. - All uids from child user namespaces are mapped into the initial user namespace before they are processed. Removing the need to add an additional check to see if the user namespace of the compared uids remains the same. - With the user namespaces compiled out the performance is as good or better than it is today. - For most operations absolutely nothing changes performance or operationally with the user namespace enabled. - The worst case performance I could come up with was timing 1 billion cache cold stat operations with the user namespace code enabled. This went from 156s to 164s on my laptop (or 156ns to 164ns per stat operation). - (uid_t)-1 and (gid_t)-1 are reserved as an internal error value. Most uid/gid setting system calls treat these value specially anyway so attempting to use -1 as a uid would likely cause entertaining failures in userspace. - If setuid is called with a uid that can not be mapped setuid fails. I have looked at sendmail, login, ssh and every other program I could think of that would call setuid and they all check for and handle the case where setuid fails. - If stat or a similar system call is called from a context in which we can not map a uid we lie and return overflowuid. The LFS experience suggests not lying and returning an error code might be better, but the historical precedent with uids is different and I can not think of anything that would break by lying about a uid we can't map. - Capabilities are localized to the current user namespace making it safe to give the initial user in a user namespace all capabilities.

Even the enthusiast hobbyist community seems to have dried up close to ten years ago, based on what you can find searching various websites dedicated to the relatively short lived hardware. So lets remove the support relating to CONFIG_MCA. There is no point carrying this forward, wasting cycles doing routine maintenance on it; wasting allyesconfig build time on validating it, wasting I/O on git grep'ping over it, and so on." Let's see if anybody screams. It generally has compiled, and James Bottomley pointed out that there was a MCA extension from NCR that allowed for up to 4GB of memory and PPro-class machines. So in *theory* there may be users out there. But even James (technically listed as a maintainer) doesn't actually have a system, and while Alan Cox claims to have a machine in his cellar that he offered to anybody who wants to take it off his hands, he didn't argue for keeping MCA support either. So we could bring it back. But somebody had better speak up and talk about how they have actually been using said MCA hardware with modern kernels for us to do that. And David already took the patch to delete all the networking driver code (commit a5e371f61ad3: "drivers/net: delete all code/drivers depending on CONFIG_MCA"). * 'delete-mca' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: MCA: delete all remaining traces of microchannel bus support. scsi: delete the MCA specific drivers and driver code serial: delete the MCA specific 8250 support. arm: remove ability to select CONFIG_MCA

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "This is the first big chunk for 3.5 merges of sound stuff. There are a few big changes in different areas. First off, the streaming logic of USB-audio endpoints has been largely rewritten for the better support of "implicit feedback". If anything about USB got broken, this change has to be checked. For HD-audio, the resume procedure was changed; instead of delaying the resume of the hardware until the first use, now waking up immediately at resume. This is for buggy BIOS. For ASoC, dynamic PCM support and the improved support for digital links between off-SoC devices are major framework changes. Some highlights are below: * HD-audio - Avoid accesses of invalid pin-control bits that may stall the codec - V-ref setup cleanups - Fix the races in power-saving code - Fix the races in codec cache hashes and connection lists - Split some common codes for BIOS auto-parser to hda_auto_parser.c - Changed the PM resume code to wake up immediately for buggy BIOS - Creative SoundCore3D support - Add Conexant CX20751/2/3/4 codec support * ASoC - Dynamic PCM support, allowing support for SoCs with internal routing through components with tight sequencing and formatting constraints within their internal paths or where there are multiple components connected with CPU managed DMA controllers inside the SoC. - Greatly improved support for direct digital links between off-SoC devices, providing a much simpler way of connecting things like digital basebands to CODECs. - Much more fine grained and robust locking, cleaning up some of the confusion that crept in with multi-component. - CPU support for nVidia Tegra 30 I2S and audio hub controllers and ST-Ericsson MSP I2S controolers - New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124, Texas Instruments LM49453. - Some regmap changes needed by the Tegra I2S driver. - mc13783 audio support. * Misc - Rewrite with module_pci_driver() - Xonar DGX support for snd-oxygen - Improvement of packet handling in snd-firewire driver - New USB-endpoint streaming logic - Enhanced M-audio FTU quirks and relevant cleanups - Increment the support of OSS devices to 256 - snd-aloop accuracy improvement There are a few more pending changes for 3.5, but they will be sent slightly later as partly depending on the changes of DRM."

2012-05-21timers: Fixup the Kconfig consolidation falloutThomas Gleixner
Sigh, I missed to check which architecture Kconfig files actually include the core Kconfig file. There are a few which did not. So we broke them. Instead of adding the includes to those, we are better off to move the include to init/Kconfig like we did already with irqs and others. This does not change anything for the architectures using the old style periodic timer mode. It just solves the build wreckage there. For those architectures which use the clock events infrastructure it moves the include of the core Kconfig file to "General setup" which is a way more logical place than having it at random locations specified by the architecture specific Kconfigs.

2012-05-21ARM: dma-mapping: use PMD size for section unmapVitaly Andrianov
The dma_contiguous_remap() function clears existing section maps using the wrong size (PGDIR_SIZE instead of PMD_SIZE). This is a bug which does not affect non-LPAE systems, where PGDIR_SIZE and PMD_SIZE are the same. On LPAE systems, however, this bug causes the kernel to hang at this point. This fix has been tested on both LPAE and non-LPAE kernel builds. Signed-off-by: Vitaly Andrianov <vitalya@ti.com> Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>
2012-05-21ARM: integrate CMA with DMA-mapping subsystemMarek Szyprowski
This patch adds support for CMA to dma-mapping subsystem for ARM architecture. By default a global CMA area is used, but specific devices are allowed to have their private memory areas if required (they can be created with dma_declare_contiguous() function during board initialisation). Contiguous memory areas reserved for DMA are remapped with 2-level page tables on boot. Once a buffer is requested, a low memory kernel mapping is updated to to match requested memory access type. GFP_ATOMIC allocations are performed from special pool which is created early during boot. This way remapping page attributes is not needed on allocation time. CMA has been enabled unconditionally for ARMv6+ systems.

2012-05-21ARM: dma-mapping: add support for IOMMU mapperMarek Szyprowski
This patch add a complete implementation of DMA-mapping API for devices which have IOMMU support. This implementation tries to optimize dma address space usage by remapping all possible physical memory chunks into a single dma address space chunk. DMA address space is managed on top of the bitmap stored in the dma_iommu_mapping structure stored in device->archdata. Platform setup code has to initialize parameters of the dma address space (base address, size, allocation precision order) with arm_iommu_create_mapping() function. To reduce the size of the bitmap, all allocations are aligned to the specified order of base 4 KiB pages. dma_alloc_* functions allocate physical memory in chunks, each with alloc_pages() function to avoid failing if the physical memory gets fragmented. In worst case the allocated buffer is composed of 4 KiB page chunks. dma_map_sg() function minimizes the total number of dma address space chunks by merging of physical memory chunks into one larger dma address space chunk. If requested chunk (scatter list entry) boundaries match physical page boundaries, most calls to dma_map_sg() requests will result in creating only one chunk in dma address space. dma_map_page() simply creates a mapping for the given page(s) in the dma address space. All dma functions also perform required cache operation like their counterparts from the arm linear physical memory mapping version.

2012-05-21ARM: dma-mapping: implement dma sg methods on top of any generic dma opsMarek Szyprowski
This patch converts all dma_sg methods to be generic (independent of the current DMA mapping implementation for ARM architecture). All dma sg operations are now implemented on top of respective dma_map_page/dma_sync_single_for* operations from dma_map_ops structure. Before this patch there were custom methods for all scatter/gather related operations. They iterated over the whole scatter list and called cache related operations directly (which in turn checked if we use dma bounce code or not and called respective version). This patch changes them not to use such shortcut. Instead it provides similar loop over scatter list and calls methods from the device's dma_map_ops structure. This enables us to use device dependent implementations of cache related operations (direct linear or dma bounce) depending on the provided dma_map_ops structure.

2012-05-21ARM: dma-mapping: remove offset parameter to prepare for generic dma_opsMarek Szyprowski
This patch removes the need for the offset parameter in dma bounce functions. This is required to let dma-mapping framework on ARM architecture to use common, generic dma_map_ops based dma-mapping helpers. Background and more detailed explaination: dma_*_range_* functions are available from the early days of the dma mapping api. They are the correct way of doing a partial syncs on the buffer (usually used by the network device drivers). This patch changes only the internal implementation of the dma bounce functions to let them tunnel through dma_map_ops structure. The driver api stays unchanged, so driver are obliged to call dma_*_range_* functions to keep code clean and easy to understand. The only drawback from this patch is reduced detection of the dma api abuse. Let us consider the following code: dma_addr = dma_map_single(dev, ptr, 64, DMA_TO_DEVICE); dma_sync_single_range_for_cpu(dev, dma_addr+16, 0, 32, DMA_TO_DEVICE); Without the patch such code fails, because dma bounce code is unable to find the bounce buffer for the given dma_address. After the patch the above sync call will be equivalent to: dma_sync_single_range_for_cpu(dev, dma_addr, 16, 32, DMA_TO_DEVICE); which succeeds. I don't consider this as a real problem, because DMA API abuse should be caught by debug_dma_* function family. This patch lets us to simplify the internal low-level implementation without chaning the driver visible API.
