Hi, This is fifth approach for replacing struct dma_attrs with unsigned long. The main patch (1/44) doing the change is split into many subpatches for easier review (2-42). They should be squashed together when applying. Rebased on v4.7-rc5. For easier testing the patchset is available here: repo: https://github.com/krzk/linux branch: for-next/dma...

...c5 so it missed some ongoing changes. This is just rebase on next-20160713. For easier testing the patchset is available here: repo: https://github.com/krzk/linux branch: for-next/dma-attrs-const-v6 Changes since v5 ================ 1. New patches: 1/46: [media] mtk-vcodec: Remove unused dma_attrs 44/46: remoteproc: qcom: Use unsigned long for dma_attrs 2. 19/46: rebased on next, some more changes inside 3. Added accumulated acks: Marek Szyprowski, Richard Kuo, Konrad Rzeszutek Wilk, Daniel Vetter and Joerg Roedel. Changes since v4 ================ 1. Collect some acks. Still need m...

Hi, This is fourth approach for replacing struct dma_attrs with unsigned long. The main patch (1/44) doing the change is split into many subpatches for easier review (2-42).

Hi, This is third approach (complete this time) for replacing struct dma_attrs with unsigned long. The main patch (2/45) doing the change is split into many subpatches for easier review (3-43).
