mmc: sdio: fix alignment issue in struct sdio_func

2017-04-18T17:18:07+00:00

Certain 64-bit systems (e.g. Amlogic Meson GX) require buffers to be used for DMA to be 8-byte-aligned. struct sdio_func has an embedded small DMA buffer not meeting this requirement. When testing switching to descriptor chain mode in meson-gx driver SDIO is broken therefore. Fix this by allocating the small DMA buffer separately as kmalloc ensures that the returned memory area is properly aligned for every basic data type.

mmc: block: Fix is_waiting_last_req set incorrectly

2017-03-14T16:13:25+00:00

Commit 15520111500c ("mmc: core: Further fix thread wake-up") allowed a queue to release the host with is_waiting_last_req set to true. A queue waiting to claim the host will not reset it, which can result in the queue getting stuck in a loop.

mmc: core: Fix access to HS400-ES devices

2017-03-14T16:07:45+00:00

HS400-ES devices fail to initialize with the following error messages. mmc1: power class selection to bus width 8 ddr 0 failed mmc1: error -110 whilst initialising MMC card This was seen on Samsung Chromebook Plus. Code analysis points to commit 3d4ef329757c ("mmc: core: fix multi-bit bus width without high-speed mode"), which attempts to set the bus width for all but HS200 devices unconditionally. However, for HS400-ES, the bus width is already selected. Cc: Anssi Hannula Cc: Douglas Anderson Cc: Brian Norris Fixes: 3d4ef329757c ("mmc: core: fix multi-bit bus width ...")

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:27+00:00

We are going to move scheduler ABI details to , which will be used from a number of .c files. Create empty placeholder header that maps to . Include the new header in the files that are going to need it.
