Allocate device structures dynamically instead of having them embedded in ide_hwif_t: * Remove needless zeroing of port structure from ide_init_port_data(). * Add ide_hwif_t.devices[MAX_DRIVES] (table of pointers to the devices). * Add ide_port_{alloc,free}_devices() helpers and use them respectively in ide_{host,free}_alloc(). * Convert all users of ->drives[] to use ->devices[] instead. While at it: * Use drive->dn for the slave device check in scc_pata.c.

Now that (almost) all host drivers have been fixed not to abuse ide_lock and core code usage of ide_lock has been sanitized we may safely replace ide_lock by per-hwgroup locks. This patch is partially based on earlier patch from Ravikiran G Thirumalai. While at it: - don't use deprecated HWIF() and HWGROUP() macros - update locking documentation in ide.h v2: Add missing spin_lock_init(&hwgroup->lock). (Noticed by Elias Oltmanns) Cc: Vaibhav V.

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:

After rework settings will be no longer created dynamically for each device so we need to make some fixups first. * Use set_[ksettings,unmaskirq]() as a set function for ["keepsettings","unmaskirq"] setting. * Allow writes to ["io_32bit","unmaskirq"] settings also when drive->no_[io_32bit,unmask] is set (this is checked later inside set_[io_32bit,unmaskirq]() anywyay and keeps consistency with the corresponding HDIO_SET_[32BIT,UNMASKINTR] ioctls). * Use max possible multi sectors value (16) as an allowed max for "multcount" setting. set_multcount() set function checks against device's max possbile value anyway and it makes the proc setting consistent with the corresponding HDIO_SET_MULTCOUNT ioctl.

Make drive->id an unnamed union so id can be accessed either by using 'u16 *id' or 'struct hd_driveid *driveid'. Then convert all existing drive->id users accordingly (using 'u16 *id' when possible).
