2009-01-06ide: remove now redundant ->cur_dev checksBartlomiej Zolnierkiewicz
* ->cur_dev should now be always valid if ->handler is set so remove redundant checks from ide_intr() and ide_timer_expiry(). * Apply CodingStyle fixups in ide_timer_expiry() while at it. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2009-01-06ide: make "paranoia" ->handler check in ide_intr() more strictBartlomiej Zolnierkiewicz
If ->handler is set while it shouldn't be it indicates deep problems so BUG_ON()-ning and preventing further damage is much more appropriate than merely printing an error message. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2009-01-06ide: Fix drive's DWORD-IO handlingMario Schwalbe
According the documentation, id[ATA_ID_DWORD_IO] is non-zero if the drive supports dword IO, while the code disables support by setting IDE_DFLAG_NO_IO_32BIT. In addition, this word has been reused by the ATA8 specification. This patch fixes both cases.

2009-01-06ide: dynamic allocation of device structuresBartlomiej Zolnierkiewicz
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.

2009-01-06ide: use lock bitops for ports serialization (v2)Bartlomiej Zolnierkiewicz
* Add ->host_busy field to struct ide_host and use it's first bit together with lock bitops to provide new ports serialization method. * Convert core IDE code to use new ide_[un]lock_host() helpers. This removes the need for taking hwgroup->lock if host is already busy on serialized hosts and makes it possible to merge ide_hwgroup_t into ide_hwif_t (done in the later patch). * Remove no longer needed ide_hwgroup_t.busy and ide_[un]lock_hwgroup(). * Update do_ide_request() documentation. v2: * ide_release_lock() should be called inside IDE_HFLAG_SERIALIZE check. * Add ide_hwif_t.busy flag and ide_[un]lock_port() for serializing devices on a port.

2009-01-06ide: remove hwgroup->hwif and {drive,hwif}->nextBartlomiej Zolnierkiewicz
* Add 'int port_count' field to ide_hwgroup_t to keep the track of the number of ports in the hwgroup. Then update init_irq() and ide_remove_port_from_hwgroup() to use it. * Remove no longer needed hwgroup->hwif, {drive,hwif}->next, ide_add_drive_to_hwgroup() and ide_remove_drive_from_hwgroup() (hwgroup->drive now only denotes the currently active device in the hwgroup). * Update locking documentation in <linux/ide.h>. While at it: * Rename ->drive field in ide_hwgroup_t to ->cur_dev. * Use __func__ in ide_timer_expiry(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-01-06ide: use per-port IRQ handlersBartlomiej Zolnierkiewicz
Use hwif instead of hwgroup as {request,free}_irq()'s cookie, teach ide_intr() to return early for non-active serialized ports, modify unexpected_intr() accordingly and then use per-port IRQ handlers instead of per-hwgroup ones. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2009-01-06ide: add ->cur_port to struct ide_host and use it for serialized hostsBartlomiej Zolnierkiewicz

2009-01-06ide: fix LOCKDEP warningBartlomiej Zolnierkiewicz
commit 295f00042aaf6b553b5f37348f89bab463d4a469 ("ide: don't execute the next queued command from the hard-IRQ context") overlooked that ide_do_drive_cmd() (used for REQUEST SENSE command handling) may still invoke do_ide_request() (->request_fn) in the hard-IRQ context through blk_start_queueing(). This resulted in a LOCKDEP warning after commit b599bc7a1199419e122cb2e9ec6b0fa2cfbbc17b ("ide: use per-device request queue locks (v2)"). Since calling blk_start_queuing() in ide_do_drive_cmd() doesn't make much sense as the port is already marked as busy (so the execution of the new command will be deferred anyway) then just remove it fixing LOCKDEP warning and saving some CPU cycles at the same time.

2009-01-06[SCSI] fc transport: restore missing dev_loss_tmo callback to LLDDJames Smart
When we reworked the transport for the rport lifetimes, in cases where the rport was reused as a container for tgt id bindings, we inadvertantly removed the callback to the driver indicating that dev_loss_tmo had fired.
