Merge tag 'amdkfd-fixes-2014-12-30' of git://people.freedesktop.org/~gabbayo/linux into linus 

Highlights:

- Link order changes in drm/Makefile and drivers/Makefile to fix issue
  when amdkfd, radeon and amd_iommu_v2 are compiled inside the kernel
  image.

- Consider kernel configuration (using #IFDEFs) when radeon initializes
  amdkfd, due to a specific configuration that makes symbol_request()
  return a non-NULL value when a symbol doesn't exists. Rusty Russel
  is helping me to find the root cause, but it may take a while because
  of year-end so I'm sending this as a band-aid solution.

* tag 'amdkfd-fixes-2014-12-30' of git://people.freedesktop.org/~gabbayo/linux:
  drm/radeon: Init amdkfd only if it was compiled
  amdkfd: actually allocate longs for the pasid bitmask
  drm: Put amdkfd before radeon in drm Makefile
  drivers: Move iommu/ before gpu/ in Makefile
  amdkfd: Remove duplicate include
  amdkfd: Fixing topology bug in building sysfs nodes
  amdkfd: Fix accounting of device queues
