[PATCH v2 0/5] clk: add fsl-flexspi driver

On Layerscape SoCs which feature the FlexSPI controller there is a single register which can control the divider value. The base frequency is the platform PLL. Right now the LS1028A and the LX2160A aren't able to switch the SCK frequency on the FlexSPI interface. Add a new clock driver which opera

[PATCH v2 3/5] clk: fsl-flexspi: new driver

Add support for the FlexSPI clock on Freescale Layerscape SoCs. The clock is a simple divider based one and is located inside the device configuration space (DCFG). This will allow switching the SCK frequencies for the FlexSPI interface on the LS1028A and the LX2160A. Signed-off-by: Michael Walle

[PATCH v2 0/3] MPEG-2 stateless API cleanup

Hello everyone, Following the H.264 API cleanup, and with all the lessons learned from it, here's a revisit on the MPEG-2 API. The biggest changes are: * Drop slice size and offset parameters, given the API doesn't seem to be designed to work per-slice. * Convert all the 1-bit syntax elements

[PATCH v2 3/3] media: uapi: mpeg2: Split sequence and picture parameters

Typically, bitstreams are composed of one sequence header NAL unit, followed by a number of picture header and picture coding extension NAL units. Each picture can be composed by a number of slices. Let's split the MPEG-2 uAPI to follow these semantics more closely, allowing more usage flexibility

[PATCH v2 1/3] media: uapi: mpeg2: Cleanup flags

Our current MPEG-2 uAPI uses 1-byte fields for MPEG-2 boolean syntax elements. Clean these by adding a 'flags' field and flag macro for each boolean syntax element. Move quantization "load" flags to struct v4l2_mpeg2_picture, so the applications can skip passing the quantization matrices (by not s

[PATCH v2 2/3] media: uapi: mpeg2: Remove unused slice size and offset

The MPEG2_SLICE_PARAMS control is designed to refer to a single slice. Conversely, in each request the OUTPUT buffer is expected to hold a single slice, so the offset and size fields are not needed. The start of the slice is aligned to the start of the buffer, and the buffer's plane payload size i

[PATCH 5/5] mm: migrate: return -ENOSYS if THP migration is unsupported

In the current implementation unmap_and_move() would return -ENOMEM if THP migration is unsupported, then the THP will be split. If split is failed just exit without trying to migrate other pages. It doesn't make too much sense since there may be enough free memory to migrate other pages and ther

[PATCH 2/5] mm: migrate: simplify the logic for handling permanent failure

When unmap_and_move{_huge_page}() returns !-EAGAIN and !MIGRATEPAGE_SUCCESS, the page would be put back to LRU or proper list if it is non-LRU movable page. But, the callers always call putback_movable_pages() to put the failed pages back later on, so it seems not very efficient to put every singl

I want scrollback buffer back

I've been using scrollback ever since discovering it well over a decade ago. It's been sorely missed where encountered, so wherever I can, I'll be sticking with pre-5.9+ as long as possible, unless scrollback is restored. I'm not a developer (or a lkml subscriber), just a user/tester of a number
