Merge branch 'drm-next-3.8' of git://people.freedesktop.org/~agd5f/linux into drm-next
Alex writes: "adds support for the asynchronous DMA engines on r6xx-SI. These engines are used for ttm bo moves and VM page table updates currently. They could also be exposed via the CS ioctl for userspace use, but I haven't had a chance to add proper CS checker patches for them yet. These patches have been tested extensively internally for months, so they should be pretty solid." * 'drm-next-3.8' of git://people.freedesktop.org/~agd5f/linux: drm/radeon: use DMA engine for VM page table updates on SI drm/radeon: add dma engine support for vm pt updates on si (v2) drm/radeon: use DMA engine for VM page table updates on cayman/TN drm/radeon: add dma engine support for vm pt updates on ni (v5) drm/radeon: use async dma for ttm buffer moves on 6xx-SI drm/radeon/kms: add support for dma rings to radeon_test_moves() drm/radeon/kms: Add initial support for async DMA on SI drm/radeon/kms: Add initial support for async DMA on cayman/TN drm/radeon/kms: Add initial support for async DMA on evergreen drm/radeon/kms: Add initial support for async DMA on r6xx/r7xx
