[pull] radeon drm-fixes-3.15

[Christian König]

Hi Dave,

by your request I've removed Alex's I2C mutex patch from the branch. I 
would like to keep the VCE patch, cause it actually fixed a serious bug 
for me, but I've fixed the formal error of the missing Signed-off-by line.

Additional to that we have two new fixes from Jerome and Alex, both are 
CC stable as well so important enough for 3.15.

So this is the resend pull of stashed up radeon fixes for 3.15. 
Highlights are:
1. Avoid sending SIGBUS on CPU access just because kernel can't handle 
buffer placement.
2. Some fixes for VM page table updates and buffer placements.
3. Fixing two typos in the PLL and SI register spec.
4. Checking VCE buffers ranges.
5. Mullins and non-VGA pci class fixes.
6. A PX power management fix.
7. Fix for a crash if acceleration fails to initialize.

The following changes since commit 4ba4801d73d14690ed15774424e8b1d4c18323a5:
