[meta-freescale] imxvpudec crash with 3.14.28 and gstreamer1.0

[Carlos Rafael Giani]

This is strange. For me, it looped over 160 times before I stopped it. 
I'll compare your config to that of the boundarydevices kernel. (Also 
note that this kernel might have patches that yours doesn't.)

Try to repeatedly print out the contents of /proc/buddyinfo, especially 
the DMA row. I did, and the bins stayed relatively stable. If these bins 
rapidly decrease for you, then we might be looking at a kernel issue, or 
a problem with imx-vpu.
