Changes since v1:
* Rebased
* Several fixes
* Conditional IOMMU change carried over from previous patch series and updated

AMDGPU:
Patches 1-5 are minor cleanups and fixes
Patches 6-10 add and implement KFD->KGD interfaces for GPUVM

AMDKFD:
Patch 11: Make IOMMU conditional (carried over from previous patch series)
Patch 12-13: small fixes
Patches 14-25 add all the GPUVM memory management functionality
