Subject: Please add patch "staging: ion: ion_cma_heap: Don't directly use dma_common_get_sgtable" to 4.1 stable
Date: Thu, 14 Apr 2016 11:08:01 +0800	[thread overview]
Message-ID: <20160414030801.GB6949@x250> (raw)

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
