This is a note to let you know that I have just added a patch titled [media] media: s5p-mfc: fix mmap support for 64bit arch to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt11. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 9338a4050efcab64db8e8c88c0a00d3dcdc4516c Mon Sep 17 00:00:00 2001 From: Marek Szyprowski <m.szyprowski@samsung.com> Date: Wed, 4 Mar 2015 05:55:21 -0800 Subject: [media] media: s5p-mfc: fix mmap support for 64bit arch commit 05b676ab42f624425d5f6519276e506b812fa058 upstream. TASK_SIZE is depends on the systems architecture (32 or 64 bits) and it should not be used for defining offset boundary for mmaping buffers for CAPTURE and OUTPUT queues. This patch fixes support for MMAP calls on the CAPTURE queue on 64bit architectures (like ARM64).
