Hi stable team,
This is the first time I request to add a patch that is already on
upstream to stable kernel. I'm not sure if this is the correct
procedure, but I'm following option 2 in stable_kernel_rules.txt to
request add the following patch to 4.1 and 4.4 stable kernel.
commit 70bc916b2c80913753fb188d4daee50a64d21ba0 upstream.
We are seeing a problem on an ARM64 platform running Android 4.4 + Linux
4.1. A sanity check in GPU driver detects that the scatterlist
created by ION driver does not have a valid dma_length, and hence
refuses to work. And the requested patch fixes our problem.
Thanks,
Shawn

Now applied to 4.4 and 4.5-stable trees, thanks.
