Hi stable team,
Please add the following upstream patch to 4.1 stable kernel.
commit 56fa2ece881348d314800b858581f2ae950f8e20 upstream.
We're running a arm 32-bit device with Android 4.4 + Linux 4.1, and
seeing that when ION driver allocates a buffer from CMA pool sitting
on high memory, the scatterlist created for that buffer links to a wrong
physical page. The above patch fixes the problem for us.
Thanks,
Shawn
