+Subject: dma-buf: add support for compat ioctl
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Marek Szyprowski <m.szyprowski@samsung.com>
+
+commit 888022c0473d079bff9b47fb50434b1f20f8f37f upstream.
+
+Add compat ioctl support to dma-buf. This lets one to use DMA_BUF_IOCTL_SYNC
+ioctl from 32bit application on 64bit kernel. Data structures for both 32
+and 64bit modes are same, so there is no need for additional translation
+layer.
