Subject: [media] media: s5p-mfc: fix mmap support for 64bit arch Author: Marek Szyprowski <m.szyprow...@samsung.com> Date: Wed Mar 4 05:55:21 2015 -0800 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).
