Re: [PATCHv8 00/10] ARM: DMA-mapping framework redesign

Hello Marek,

I have tested below patch series for vanilla 3.4-rc2 (without videobuf2 support for dmabuf patches) with and without IOMMU support on origen board. These patches are good now. You can add:

Tested-By: Subash Patel <subash.ramaswamy@xxxxxxxxxx> for whole series.

Regards,
Subash

Hello,

Linux v3.4-rc2, which include dma-mapping preparation patches, has been
released two days ago, now it's time for the next spin of ARM
dma-mapping redesign patches. This version includes various fixes posted
separately to v7, mainly related to incorrect io address space bitmap
setup and a major issue with broken mmap for memory which comes from
dma_declare_coherent(). The patches have been also rebased onto Linux
v3.4-rc2 which comes with dma_map_ops related changes.

The code has been tested on Samsung Exynos4 'UniversalC210' and NURI
boards with IOMMU driver posted by KyongHo Cho, I will put separate
branch which shows how to integrate this driver with this patchset.

The patches are also available on my git repository at:
