* common: dma-mapping: add support for generic dma_mmap_* callsMarek Szyprowski2012-07-309-40/+95
| | | | | | | | | | | | | | | | | Commit 9adc5374 ('common: dma-mapping: introduce mmap method') added a generic method for implementing mmap user call to dma_map_ops structure. This patch converts ARM and PowerPC architectures (the only providers of dma_mmap_coherent/dma_mmap_writecombine calls) to use this generic dma_map_ops based call and adds a generic cross architecture definition for dma_mmap_attrs, dma_mmap_coherent, dma_mmap_writecombine functions. The generic mmap virt_to_page-based fallback implementation is provided for architectures which don't provide their own implementation for mmap method.

* ARM: dma-mapping: fix error path for memory allocation failureMarek Szyprowski2012-07-301-1/+1
| | | | | | | | | This patch fixes incorrect check in error path. When the allocation of first page fails, the kernel ops appears due to accessing -1 element of the pages array. Reported-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>

* ARM: dma-mapping: remove custom consistent dma regionMarek Szyprowski2012-07-306-323/+181
| | | | | | | | | | | | | | This patch changes dma-mapping subsystem to use generic vmalloc areas for all consistent dma allocations. This increases the total size limit of the consistent allocations and removes platform hacks and a lot of duplicated code. Atomic allocations are served from special pool preallocated on boot, because vmalloc areas cannot be reliably created in atomic context.

* scatterlist: add sg_alloc_table_from_pages functionTomasz Stanislawski2012-07-302-0/+68
| | | | | | | | | | | | | | | | | | | | | | This patch adds a new constructor for an sg table. The table is constructed from an array of struct pages. All contiguous chunks of the pages are merged into a single sg nodes. A user may provide an offset and a size of a buffer if the buffer is not page-aligned. The function is dedicated for DMABUF exporters which often perform conversion from an page array to a scatterlist. Moreover the scatterlist should be squashed in order to save memory and to speed-up the process of DMA mapping using dma_map_sg. The code is based on the patch 'v4l: vb2-dma-contig: add support for scatterlist in userptr mode' and hints from Laurent Pinchart.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge emailed kgdb dmesg fixups patches from Anton Vorontsov: "The dmesg command appears to be broken after the printk rework. The old logic in the kdb code makes no sense in terms of current printk/logging storage format, and KDB simply hangs forever upon entering 'dmesg' command. The first patch revives the command by switching to kmsg_dumper iterator. As a side-effect, the code is now much more simpler. A few changes were needed in the printk.c: we needed unlocked variant of the kmsg_dumper iterator, but these can surely wait for 3.6. It's probably too late even for the first patch to go to 3.5, but I'll try to convince otherwise. :-) Here we go: - The current code is broken for sure, and has no hope to work at all. It is a regression - The new code works for me, and probably works for everyone else; - If it compiles (and I urge everyone to compile-test it on your setup), it hardly can make things worse." * Merge emailed patches from Anton Vorontsov: (4 commits) kdb: Switch to nolock variants of kmsg_dump functions printk: Implement some unlocked kmsg_dump functions printk: Remove kdb_syslog_data kdb: Revive dmesg command

Re-calculate current_cpu_data.tlbsize on the boot cpu after enabling and waking up other threads. The secondary CPUs do not need this logic because the threads are enabled on the secondary cores at wakeup and before cpu_probe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MSI interrupts do not work on XLS after commit a776c49 ( "PCI: msi: Disable msi interrupts when we initialize a pci device" ) because the change disables MSI interrupts on the XLS PCIe bridges during the PCI enumeration. Fix this by enabling MSI interrupts on the bridge in the arch_setup_msi_irq() function. A new function xls_get_pcie_link() has been introduced to get the PCI device corresponding to the top level PCIe bridge on which MSI has to be enabled. Also, update get_irq_vector() to use the new xls_get_pcie_link() function and PCI_SLOT() macro for determining the IRQ of PCI devices.
