v4l2_get_timestamp() produces a monotonic timestamp but unlike ktime_get_ts(), it uses struct timeval instead of struct timespec, saving the drivers the conversion job when getting timestamps for v4l2_buffer's timestamp field.

Explicit checks for the JPEG pixel format in soc_mbus_bytes_per_line() and soc_mbus_image_size() are superfluous, because also without them these functions will perform correctly. The former will return 0 based on packing == SOC_MBUS_PACKING_VARIABLE and the latter will simply multiply the user-provided line length by the image height to obtain a frame buffer size estimate. The original version of the "media: soc_camera: don't clear pix->sizeimage in JPEG mode" patch was correct and my amendment, adding these two checks was superfluous.

Video Engine Unit (VEU) is an IP block, found in multiple SuperH and ARM- based sh-mobile and r-mobile SoCs, capable of processing video data. It can perform colour-space conversion, scaling and several filtering transformations. This patch adds an initial implementation of a mem2mem V4L2 driver for VEU. So far only conversion from NV12 to RGB565 is supported. Further functionality shall be added in the future. This driver is based on a VEU vidix driver by Magnus Damm.

This patch removes the dependendency of VIDEO_AU0828 on VIDEO_V4L2 by creating a new Kconfig option, VIDEO_AU0828_V4L2, which enables analog video capture support and depends on VIDEO_V4L2 itself. With VIDEO_AU0828_V4L2 disabled, the driver will only support digital television and will not depend on the v4l2-core. With VIDEO_AU0828_V4L2 enabled, the driver will be built with the analog v4l2 support included. By default, the VIDEO_AU0828_V4L2 option will be set to Y, so as to preserve the original behavior.

Merge 'block-dev' branch. I was going to just mark everything here for stable and leave it to the 3.8 merge window, but having decided on doing another -rc, I migth as well merge it now. This removes the bd_block_size_semaphore semaphore that was added in this release to fix a race condition between block size changes and block IO, and replaces it with atomicity guaratees in fs/buffer.c instead, along with simplifying fs/block-dev.c. This removes more lines than it adds, makes the code generally simpler, and avoids the latency/rt issues that the block size semaphore introduced for mount. I'm not happy with the timing, but it wouldn't be much better doing this during the merge window and then having some delayed back-port of it into stable. * block-dev: blkdev_max_block: make private to fs/buffer.c direct-io: don't read inode->i_blkbits multiple times blockdev: remove bd_block_size_semaphore again fs/buffer.c: make block-size be per-page and protected by the page lock

The tps65910_rtc data is registered as the platform driver data in _probe(= ). Therefore the tps65910_rtc should be used on unregistering the rtc device. And device pointer should be retrieved from the platform_device structure. This patch fixes the below oops: Unable to handle kernel NULL pointer dereference at virtual address 00000008 Modules linked in: rtc_tps65910(-) CPU: 0 Not tainted (3.7.0-rc7-next-20121128-g6b1f974-dirty #7) PC is at tps65910_rtc_alarm_irq_enable+0x20/0x2c [rtc_tps65910] (tps65910_rtc_alarm_irq_enable+0x20/0x2c [rtc_tps65910]) (tps65910_rtc_remove+0x18/0x28 [rtc_tps65910]) (platform_drv_remove+0x18/0x1c) (__device_release_driver+0x70/0xcc) (driver_detach+0xb4/0xb8) (bus_remove_driver+0x7c/0xc0) (sys_delete_module+0x148/0x21c) Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

It apepars that this patch was innocent, and we hope that "mm: avoid waking kswapd for THP allocations when compaction is deferred or contended" will fix the final kswapd-spinning cause.
