To be able to do SDIO the s3cmci driver has to support non-word-sized transfers. Change pio_words into pio_bytes and fix up all the places where it is used. This variant of the patch will not overrun the buffer when reading an odd number of bytes. When writing, this variant will still read past the end of the buffer, but since the driver can't support non-word- aligned transfers anyway, this should not be a problem, since a word-aligned transfer will never cross a page boundary. This has been tested with a CSR SDIO Bluetooth Type A device on a Samsung S3C24A0 processor.

Put some information (and pointers to more) into the kernel's doc tree, describing briefly the interface to the kernel's disk head unloading facility. Information about how to set up a complete shock protection system under GNU/Linux can be found on the web and is referenced accordingly. v3: Here is some final polish including various spelling corrections pointed out by Grant Grundler and Peter Moulder. Also, I have added some information about the timing constraints related to disk head parking. The patch looks more impressive than it really is and I think it would be alright just to incorporate it into the original patch so as not to clutter up the git log.

On user request (through sysfs), the IDLE IMMEDIATE command with UNLOAD FEATURE as specified in ATA-7 is issued to the device and processing of the request queue is stopped thereafter until the specified timeout expires or user space asks to resume normal operation. This is supposed to prevent the heads of a hard drive from accidentally crashing onto the platter when a heavy shock is anticipated (like a falling laptop expected to hit the floor). Port resets are deferred whenever a device on that port is in the parked state. v3: Elias Oltmanns <eo@nebensachen.de> wrote: [...] > >> 1.

Additionally, we should plug the queue when enqueueing the unpark request because there is no guarantee that the park timeout has not expired by then. Even though the chance for that to happen is very slim, the request might end up hanging in the queue until the next I/O operation is queued up. While at it, clean up the code a little: - make issue_park_cmd() a function of type void since nobody cares for the return value anyway; - use blk_start_queueing() instead of __blk_run_queue() since we don't have to worry about recursion; - remove a superfluous pointer deference in task_no_data_intr().

Follow-up to commit 5c05ff68 ("ide: switch to DMA-mapping API"): * pci_{alloc,free}_consistent() -> dma_{alloc,free}_coherent() in ide_{allocate,release}_dma_engine(). * Add ->prd_max_nents and ->prd_ent_size fields to ide_hwif_t (+ set default values in ide_allocate_dma_engine()). * Make ide_{allocate,release}_dma_engine() available also for CONFIG_BLK_DEV_IDEDMA_SFF=n. Then convert au1xxx-ide.c, scc_pata.c and sgiioc4.c to use them. * Add missing ->init_dma method to scc_pata. This patch also fixes: - ->dmatable_cpu leak for au1xxx-ide - too early realease of ->dmatable_cpu for scc_pata - wrong amount of ->dmatable_cpu memory being freed for sgiioc4 While at it: - remove superfluous ->dma_base check from ide_unregister() - return -ENOMEM on error in ide_release_dma_engine() - beautify error message in ide_release_dma_engine() Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

In function ide_devset_execute() we should use __GFP_WAIT rather than GFP_KERNEL. Also, the allocation cannot possibly fail at that point. More importantly, there is a potential memory leak in the device probing code. The infrastructure seems rather complex and I hope I haven't messed anything up by trying to fix this.
