Subject: Please add patch "staging: android: ion: Set the length of the DMA sg entries in buffer" to 4.1 and 4.4 stable kernel
Date: Thu, 14 Apr 2016 10:30:48 +0800	[thread overview]
Message-ID: <20160414023048.GA6949@x250> (raw)

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
