o Kdump capture kernel boot fails during initialization of MPT fusion driver.
(LSI Logic / Symbios Logic SAS1064E PCI-Express Fusion-MPT SAS (rev 01))
o Problem is easily reproducible, if system crashed while some disk activity
like cp operation was going on.
o After a system crash, devices are not shutdown and capture kernel starts
booting while skipping BIOS. Hence underlying device is left in operational
state. In this case scsi contoller was left with interrupt line asserted
reply FIFO was not empty. When driver starts initializing in the second
kernel, it receives the interrupt the moment request_irq() is called.
Interrupt handler, reads the message from reply FIFO and tries to access
the associated message frame and panics, as in the new kernel's context
that message frame is not valid at all.
o In this scenario, probably we should delay the request_irq() call. First
bring up the IOC, reset it if needed and then should register for irq.
o I have tested the patch with SAS1064E and 53c1030 controllers.

All registered reset callback handlers are called during reset processing.
The mptspi modules has its own reset callback handler, just recently
added for issuing domain validation after host reset. If either the mptsas or
mptfc driver are loaded, this callback could be called. Thus resulting
in domain validation being issued for sas or fibre end devices.
Fix this by having mptbase.c check the bus type against the driver
type and only call the reset handler if they match (or if it's a
non-bus specific reset handler).
Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
A race condition exists in mptfc between the thread registering a device
with the fc transport and the scan work generated by the transport.
This race existed prior to the application of the mptfc bug fix patch.
mptfc_register_dev() calls fc_remote_port_add() with the FC_RPORT_ROLE_TARGET
bit set in the rport ids passed to the function. Having this bit set causes
fc_remote_port_add() to schedule a scan of the device.
This scan can execute before mptfc_register_dev() can fill in the dd_data
in the rport structure. When this happens, mptfc_target_alloc() will fail
because dd_data is null.
Attached is a patch which fixes the problem. The patch changes the rport ids
passed to fc_remote_port_add() to not have the TARGET bit set. This prevents
the scan from being scheduled. After mptfc_register_dev() fills in the rport
dd_data field, fc_remote_port_rolechg() is called, changing the role of the
rport to TARGET. Thus, the scan is scheduled after dd_data is filled
in which prevents the failure in mptfc_target_alloc().

Driver panic when RAID logical volume was present when driver

This new API expects that all sdev's to be assocated to an rphy, however

This adds support for hot adding and removing
expanders, and its associated attached devices.
When there is a change in topology,
the fusion firmware sends the
MPI_EVENT_SAS_DISCOVERY event to the driver.
The driver will read firmware config pages
to determine what changes took place, and refresh
drivers view of the world stored in ioc->sas_topology.
Here is the details of the action the driver does:
(1) Expander Added : The mptsas_discovery_work
workqueue is called. Config pages read, and
ioc->sas_topology is refreshed. The sas_phy_add()
is called for each phy of the expander. The
expanders attached devices are added via
sas_rphy_add(). Added end devices are handled within
the MPT_ADD_DEVICE logic in mptsas_hotplug_work
workqueue.
(2) Expander Delete : The sas_rphy_delete() will be
called for the top most compenent of the parent that the
expander is attached to. The sas_rphy_delete call
will delete all the children phys, rphys, and end devices.
This is handled from mptsas_discovery_work workqueue.

This is the first half of a patch to add the generic domain validation
to mptspi. It also creates a secondary "virtual" channel for raid
component devices since these are now exported with no_uld_attach.
What Eric and I would have really liked is to export all physical
components on channel 0 and all raid components on channel 1.
Unfortunately, this would result in device renumbering on platforms with
mixed RAID/Physical devices which was considered unacceptable for
userland stability reasons.
Still to be done is to plug back the extra parameter setting and DV
pieces on reset and hotplug.

These days ioctl32.h is only used for communication of fs/compat.c and
fs/compat_ioctl.c and doesn't contain anything of interest to drivers.
Remove inclusion in various drivers.

HDIO_GETGEO is implemented in most block drivers, and all of them have to
duplicate the code to copy the structure to userspace, as well as getting
the start sector. This patch moves that to common code [1] and adds a
->getgeo method to fill out the raw kernel hd_geometry structure. For many
drivers this means ->ioctl can go away now.
[1] the s390 block drivers are odd in this respect. xpram sets ->start
to 4 always which seems more than odd, and the dasd driver shifts
the start offset around, probably because of it's non-standard
sector size.

- Removed some kmalloc's with __GFP_ZERO and replace it with memset()
because it didn't work properly.
- Fixed returned message frame in i2o_cfg_passthru() which caused raidutils
to display wrong error message in case a disk was missing.
- Fixed size of printk() in i2o_scsi.c.
- Fixed get_device() and put_device() in probing of the I2O controller.

add @uptodate argument to end_that_request_last() and @error
to rq_end_io_fn(). there's no generic way to pass error code
to request completion function, making generic error handling
of non-fs request difficult (rq->errors is driver-specific and
each driver uses it differently). this patch adds @uptodate
to end_that_request_last() and @error to rq_end_io_fn().
for fs requests, this doesn't really matter, so just using the
same uptodate argument used in the last call to
end_that_request_first() should suffice. imho, this can also
help the generic command-carrying request jens is working on.

When dpt_i2o is loaded first, i2o being loaded would cause it to call
pci_device_disable, thus breaking dpt_i2o's use of the device. Based on

This utilizes the hostdata area that is hung off of scsi_target and
scsi_device for saving unique firmware mapping. This will be required
for supporting new Fibre and SPI transport support.
This also fixs problems in error handling error code for SAS
controllers, in which the incorrect mapping was passed to the
firmware.

This patch removes almost all inclusions of linux/version.h. The 3
#defines are unused in most of the touched files.
A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.
There are also lots of #ifdef for long obsolete kernels, this was not
touched. In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.
In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch. This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other. So if any
hunk rejects or gets in the way of other patches, just drop it. My scripts
will pick it up again in the next round.
