When testing kernel with trinity, the kernel turned to tainted in that radeon CS require large memory and order is over MAX_ORDER.

kvmalloc/kvmalloc_array should be used here in that it will fallback to vmalloc if necessary.

Chen Li (3):
   drm/radeon: Use kvmalloc for CS chunks
   drm/amdgpu: Use kvmalloc for CS chunks
   drm/amdgpu: correct DRM_ERROR for kvmalloc_array

Changelog:
   v1->v2:
     * also use kvmalloc in amdgpu
     * fix a DRM_ERROR message for kvmalloc_array.
   v2->v3:
     * add missing kvfree for amdgpu CS
