* take declarations of enable_irq() et.al. to linux/interrupt.hAl Viro2007-07-2212-39/+11
| | | | | | | | | | Now that the last inlined instances are gone, all that is left to do is turning disable_irq_nosync on arm26 and m68k from defines to aliases and we are all set - we can make these externs in linux/interrupt.h uncoditional and kill remaining instances in asm/irq.h Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * [SCSI] libsas: make ATA functions selectable by a config optionJames Bottomley2007-07-226-397/+436
| | | | | | | | | | | | | | | | Not everyone wants libsas automatically to pull in libata. This patch makes the behaviour configurable, so you can build libsas with or without ATA support. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [SCSI] bsg: make class backlinksJames Bottomley2007-07-214-21/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, bsg doesn't make class backlinks (a process whereby you'd get a link to bsg in the device directory in the same way you get one for sg). This is because the bsg device is uninitialised, so the class device has nothing it can attach to. The fix is to make the bsg device point to the cdevice of the entity creating the bsg, necessitating changing the bsg_register_queue() prototype into a form that takes the generic device.

| | | | | | | | | | | | | | | | | | | | | | unfortunately, if IS_ERR(class_dev) is true, that means class_dev isn't null and the check in the error leg is pointless ... it's also asking for trouble to request unregistration of a device we haven't actually created (although it works currently).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix drivers misusing dev_to_shost Some drivers were using dev_to_shost to go from a struct device to the corresponding shost. Unfortunately, dev_to_shost only looks up the tree to find an shost (it's designed to go from a scsi_device or a scsi_target to the parent scsi_host), and these drivers were calling it with the parent of the scsi_host. I've fixed this by saving a pointer to the Scsi_Host in the drvdata, which matches what most scsi drivers do.

| * [SCSI] aacraid: add vpd to inquirySalyzyn, Mark2007-07-182-0/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Report VPD inquiry page 0x80 with an unique array creation serial number (CUID). When an array is created, the metadata stored on the physical drives gets an unique serial number. This serial number remains constant through array morphing or migration to other controllers. This patch is a forward port and modification to survive morphing and migration operations, of a similar piece of (un-attributed author) code added to the SLES10 SP1 aacraid driver. To test the results of the patch, observe that /dev/disk/by-id/ entries will show up for the arrays resulting from the udev rules. Also, as per the udev rules, 'scsi_id -g -x -a -s /block/sd? -d /dev/sd?' will report the ID_SERIAL as constructed from the inquiry data. It was reported to me that the 'ADPT' leading the serial number was bad form, that the inquiry vendor field was enough to differentiate the storage uniquely. Subsequent search found that another Adaptec AAC based driver reported the 8 hex serial number only without such adornments, so dropped ADPT to match. Resubmitting the patch with this alteration.

| * [SCSI] sas_ata: Implement sas_task_abort for ATA devicesDarrick J. Wong2007-07-184-6/+54
| | | | | | | | | | | | | | | | | | | | ATA devices need special handling for sas_task_abort. If the ATA command came from SCSI, then we merely need to tell SCSI to abort the scsi_cmnd.

| | | | | | | | | | | | | | | | | | | | | | | | | | Since the aic94xx sequencer assigns its own NCQ tags to ATA commands, it no longer makes any sense to copy the sactive field in the STP response to ata_port->sactive, as that will confuse libata. Also, libata seems to be capable of managing sactive on its own.

| * [SCSI] sas_ata: ata_post_internal should abort the sas_taskDarrick J. Wong2007-07-182-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new field, lldd_task, to ata_queued_cmd so that libata users such as libsas can associate some data with a qc. The particular ambition with this patch is to associate a sas_task with a qc; that way, if libata decides to timeout a command, we can come back (in sas_ata_post_internal) and abort the sas task. One question remains: Is it necessary to reset the phy on error, or will the libata error handler take care of it? (Assuming that one is written, of course.) This patch, as it is today, works well enough to clean things up when an ATA device probe attempt fails halfway through the probe, though I'm not sure this is always the right thing to do.
