This is yet another quick update on the patchset which replaces custom consistent dma regions usage in dma-mapping framework in favour of generic vmalloc areas created on demand for each allocation. The main purpose for this patchset is to remove 2MiB limit of dma coherent/writecombine allocations. This version addresses a few more cleanups pointed by Minchan Kim. This patch is based on vanilla v3.5 release. Best regards Marek Szyprowski Samsung Poland R&D Center Changelog: v6: - more cleanups of minor issues pointed by Minchan Kim, moved arm_dma_mmap() changes into separate patch v5: http://thread.gmane.org/gmane.linux.kernel.mm/83096 - fixed another minor issues pointed by Minchan Kim: added more comments here and there, changed pr_err() + stack_dump() to WARN(), added a fix for no-MMU systems v4: http://thread.gmane.org/gmane.linux.kernel.mm/80906 - replaced arch-independent VM_DMA flag with ARM-specific VM_ARM_DMA_CONSISTENT flag v3: http://thread.gmane.org/gmane.linux.kernel.mm/80028 - rebased onto v3.4-rc2: added support for IOMMU-aware implementation of dma-mapping calls, unified with CMA coherent dma pool - implemented changes requested by Minchan Kim: added more checks for vmarea->flags & VM_DMA, renamed some variables, removed obsole locks, squashed find_vm_area() exporting patch into the main redesign patch v2: http://thread.gmane.org/gmane.linux.kernel.mm/78563 - added support for atomic allocations (served from preallocated pool) - minor cleanup here and there - rebased onto v3.4-rc7 v1: http://thread.gmane.org/gmane.linux.kernel.mm/76703 - initial version Patch summary: Marek Szyprowski (2): mm: vmalloc: use const void * for caller argument ARM: dma-mapping: remove custom consistent dma region Documentation/kernel-parameters.txt | 2 +- arch/arm/include/asm/dma-mapping.h | 2 +- arch/arm/mm/dma-mapping.c | 486 ++++++++++++----------------------- arch/arm/mm/mm.h | 3 + include/linux/vmalloc.h | 9 +- mm/vmalloc.c | 28 ++- 6 files changed, 194 insertions(+), 336 deletions(-) -- 1.7.1.569.g6f426
