Hi, Here is the v4 patch set of amdkfd.
This version mainly contains fixes to the code published in v3 and changes to commit messages to reflect the fixes. In addition, I have added the latest version of a patch-set prepared by Joerg Roedel that allows the mm sub-system to handle TLBs which are external to the CPU (i.e handled by the IOMMU).
The patch-set is rebased over latest drm-next (3.17-rc5) and radeon's drm-next-3.18. Therefore, I removed some mm and IOMMU patches that were part of my tree in v3 as they are already merged into kernel 3.17
For people who like to review using git, the v4 patch set is located at: http://cgit.freedesktop.org/~gabbayo/linux/?h=amdkfd-v4
