Hello,

Upstream commit 888022c0473d079bff9b47fb50434b1f20f8f37f
Subject: dma-buf: add support for compat ioctl
Applicable to: 4.5+ stable kernels

The cc:stable got missed while this patch got applied for mainline; it
allows a 32-bit application to use DMA_BUF_IOCTL_SYNC with 64-bit
kernel.

Best regards,
Sumit.
