Recent changes to ioremap and unification of vmalloc regions on ARM significantly reduces the possible size of the consistent dma region and limited allowed dma coherent/writecombine allocations. This experimental patch series replaces custom consistent dma regions usage in dma-mapping framework in favour of generic vmalloc areas created on demand for each coherent and writecombine allocations. This patch is based on vanilla v3.4-rc2 release. Best regards Marek Szyprowski Samsung Poland R&D Center Patch summary: Marek Szyprowski (4): mm: vmalloc: use const void * for caller argument mm: vmalloc: export find_vm_area() function mm: vmalloc: add VM_DMA flag to indicate areas used by dma-mapping framework ARM: remove consistent dma region and use common vmalloc range for dma allocations arch/arm/include/asm/dma-mapping.h | 2 +- arch/arm/mm/dma-mapping.c | 220 +++++++----------------------------- include/linux/vmalloc.h | 10 +- mm/vmalloc.c | 31 ++++-- 4 files changed, 67 insertions(+), 196 deletions(-) -- 1.7.1.569.g6f426 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
