If an ipr adapter repeatedly fails its initialization the ipr driver will take the adapter offline and never talk to it again. This provides a method for the user to manually try the initialization again through sysfs.

If the write buffer command that is issued to the ipr adapter to update its microcode fails for some reason, the DMA buffer will never get unmapped. Move the pci_map/unmap out of the IOA reset job so that the buffer is always clearly mapped and unmapped.

IPR RAID arrays show up on a virtual scsi bus, with a scsi bus number of 255, which is generated by the adapter microcode. For the initial scan of the host, we manually scan this bus since it does not obey SAM in regards to sparse LUNs and the disk array devices do not have a consistent product id to use scsi core's blacklist. If /proc/scsi/scsi or sysfs is used to delete one of these devices, the device will not be able to get added back by rescanning the host since scsi core will see ipr's max_channel as 4, rather than 255. Update max_channel after the initial scan so that ipr raid arrays can get re-added if they get deleted.

This patch started life as a response to fedora specific ide subsystem changes that made error handling of my ATAPI tape drive fail; the specifics are in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=160868 The insertion of the statement rq->errors = err; near the end of ide_end_drive_cmd() in drivers/ide/ide-io.c means that rq->errors does not contain what it needs to in idescsi_end_request() in drivers/scsi/ide-scsi.c anymore. Recent mainline kernels now also have this change. Signed-off-by: NWillem Riede <wrlk@riede.org> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

There's an oops that sometimes shows up with SCSI transport classes in sysfs_hash_and_remove. The problem is that now, because of the class to device and vice versa symlinks, all classes have to be removed from visibility *before* the device is removed from visibility. The transport class trigger points violate this, so bring them back into conformance. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

Currently the driver takes a reference only for requests coming by way of the gendisk, not for requests coming by way of the struct device or struct scsi_device. Such requests can arrive in the rescan, flush, and shutdown pathways. The patch also makes the scsi_disk keep a reference to the underlying scsi_device, and it erases the scsi_device's pointer to the scsi_disk when the scsi_device is removed (since the pointer should no longer be used). This resolves Bugzilla entry #5237. Signed-off-by: NAlan Stern <stern@rowland.harvard.edu> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

If I/O is active on the adapter, and an unexpected interrupt is pending during initialization, the driver blows it's brains out. Since the driver didn't initiate the I/O, the data in it's internal tables will contain NULL pointers. When this condition is detected, a "flush cache and reset" is performed. The flush cache allows any pending "lazy writes" that the adapter is processing to complete ( a "must have" for a RAID adapter ) and the reset puts the adapter back into a known, good state.

Jeff Garzik <jgarzik@pobox.com> points out that this was wrong: we need to disable local interrupts while holding KM_IRQ0 due to IRQ sharing. And holding interrupts off during a big PIO opration is expensive, so we only want to do that if we know the page was highmem. So revert commit 17fd47abSigned-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

A lot of power packed into a little patch. This change eliminates the sharing between our controller-wide spinlock and the SCSI core's Scsi_Host lock. As the locking in libata was already highly compartmentalized, always referencing our own lock, and never scsi_host::host_lock. As a side effect, this change eliminates a deadlock from calling scsi_finish_command() while inside our spinlock.
