2013-02-20drm/radeon: Avoid NULL pointer dereference from atom_index_iio() allocation ↵Tim Gardner
failure Smatch anlysis: drivers/gpu/drm/radeon/atom.c:1242 atom_index_iio() error: potential null dereference 'ctx->iio'. (kzalloc returns null) Also cleaned up some checks before calls to kfree(). kfree(NULL) is OK.

2013-01-31drm/radeon: switch back to the CP ring for VM PT updatesAlex Deucher
For large VM page table updates, we can sometimes generate more packets than there is space on the ring. This happens more readily with the DMA ring since it is 64K (vs 1M for the CP). For now, switch back to the CP. For the next kernel, I have a patch to utilize IBs for VM PT updates which alleviates this problem.

2013-01-31drm/radeon: prevent crash in the ring space allocationAlex Deucher
If the requested number of DWs on the ring is larger than the size of the ring itself, return an error. In testing with large VM updates, we've seen crashes when we try and allocate more space on the ring than the total size of the ring without checking. This prevents the crash but for large VM updates or bo moves of very large buffers, we will need to break the transaction down into multiple batches. I have patches to use IBs for the next kernel.
