2012-10-02Merge branch 'for-v3.7' of ↵Linus Torvalds
git://git.linaro.org/people/mszyprowski/linux-dma-mapping Pull CMA and DMA-mapping updates from Marek Szyprowski: "This time the pull request is rather small, because the further redesign patches were not ready on time. This pull request consists of the patches which extend ARM DMA-mapping subsystem with support for CPU coherent (ACP) DMA busses. The first client of the new version is HighBank SATA driver. The second part of the pull request includes various cleanup for both CMA common code and ARM DMA-mapping subsystem." Fix up trivial add-add conflict due to the "dma-coherent" DT property being added next to the "calxeda,port-phys" property for the Calxeda AHCI controller. * 'for-v3.7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping: ARM: dma-mapping: Remove unsed var at arm_coherent_iommu_unmap_page ARM: highbank: add coherent DMA setup ARM: kill off arch_is_coherent ARM: add coherent iommu dma ops ARM: add coherent dma ops ARM: dma-mapping: Refrain noisy console message ARM: dma-mapping: Small logical clean up drivers: dma-contiguous: refactor dma_alloc_from_contiguous()

2012-09-14ARM: initial multiplatform supportRob Herring
This lets us build a multiplatform kernel for experimental purposes. However, it will not be useful for any real work, because it relies on a number of useful things to be disabled for now: * SMP support must be turned off because of conflicting symbols. Marc Zyngier has proposed a solution by adding a new SOC operations structure to hold indirect function pointers for these, but that work is currently stalled * We turn on SPARSE_IRQ unconditionally, which is not supported on most platforms. Each of them is currently in a different state, but most are being worked on. * A common clock framework is in place since v3.4 but not yet being used. Work on this is on its way. * DEBUG_LL for early debugging is currently disabled. * THUMB2_KERNEL does not work with allyesconfig because the kernel gets too big [Rob Herring]: Rebased to not be dependent on the mass mach header rename. As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank, picoxcell, mvebu, and socfpga are converted.

2012-09-14ARM: make mach/gpio.h headers optionalRob Herring
Most platforms don't need mach/gpio.h and it prevents multi-platform kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX or have lots of implicit includes pulled in by mach/gpio.h. at91 and omap have gpio clean-up pending and can drop CONFIG_NEED_MACH_GPIO_H once that is in.

2012-01-23ARM: 7293/1: logical_cpu_map: decouple CPU mapping from SMPWill Deacon
It turns out that the logical CPU mapping is useful even when !CONFIG_SMP for manipulation of devices like interrupt and power controllers when running a UP kernel on a CPU other than 0. This can happen when kexecing a UP image from an SMP kernel. In the future, multi-cluster systems running AMP configurations will require something similar for mapping cluster IDs, so it makes sense to decouple this logic in preparation for this support.
