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.

4ff42a669a [SCSI] mptspi: reset handler shouldn't be called for other bus protocols
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).

6dd727da92 [SCSI] mptfc: race between mptfc_register_dev and mptfc_target_alloc
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().

65207fedcf [SCSI] - fusion - mptfc bug fix's to prevent deadlock situations
mptbase.h

	bump version number to 3.03.09

	remove unneeded flags
	define workq and remove old fc specific locks

mptbase.c

	initialize new lock and don't initialize two removed locks

mptscsih.c

	when firmware reports target is no longer there, return
        DID_REQUEUE for fc hosts so that i/o doesn't get killed until
        the transport has an opportunity to manage the loss via its
        dev loss timer

	when the "eh_abort" routine is called, check to see if the
        driver has the command or not before looking to see if a reset
        is pending.  James Smart and I talked about this and believe
        that the API for this routine is: if driver doesn't have
        command, return SUCCESS.  This change helps prevent a target
        from being taken offline.  SUCCESS is returned because it's
        likely that the command completed after error recovery timed
        it out but before it could be aborted.

	provide a routine to queue work to newly created workq, and
        use it.

	remove "ioc" from mptscsih_abort() it was only used one time.
	the other references were via hd->ioc, so I just moved it....
	net change in references to ioc via hd->ioc is zero

	move hd->resetPending test and hd->timeouts increment to after
	the test for whether the command to be aborted remains known
	to the driver

	Make certain that the workq exists before queuing work to it.

mptfc.c

	no longer need to lock rport data structures as I was able to
	single thread the code!  I fixed up the debug code to
	eliminate compilation messages due to type mismatch in the
	printk.  Got rid of some no longer needed rport flags.
	Initialize and destroy the workq used for the rescan work.

	simplify the logic regarding the increment of
        fc_rescan_work_count.  use post increment and test for zero
        vs. pre increment and test for one; eliminate work_count
        variable: queue_work can be called with the work_lock held as
        it doesn't sleep

3c0c25b97c [SCSI] mptfusion - fix panic in mptsas_slave_configure
Driver panic when RAID logical volume was present when driver
loaded, or when a RAID logical volume was created on the fly.

This issue was created in due to recent scsi_transport_sas change,
when sas_read_port_mode_page was added into the mptsas drivers
slave_config entry point.

This new API expects that all sdev's to be assocated to an rphy, however
that is not the case for logical volumes, as they are created using
scsi_add_device, instead of sas_rphy_add().

e6b2d76a49 [SCSI] fusion - expander hotplug suport in mptsas module
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.

c92f222e1f [SCSI] mptspi: Add transport class Domain Validation
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.

9638d89a75 [SCSI] I2O: move pci_request_regions() just behind pci_enable_device()
The problem in dpt_i2o could be the pci config space accesses it
triggers as it loads, dangerous to do if there is any I/O activity going
on in the other driver (probable if a boot driver I guess).

I approve this patch to dpt_i2o.c, and am applying it to the Adaptec
branch of the driver.

Thanks for the investigation Ryoji.

---

In linux 2.6.15, data transfer does hang when both dpt_i2o
and i2o_block drivers are loaded.
It seems that location of pci_request_regions() are wrong.
I moved it just behind pci_enable_device() like other drivers,
and it becomes fine.

a885c8c431 [PATCH] Add block_device_operations.getgeo block device method
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.

for fs requests, this doesn't really matter, so just using the

workqueue on the 1st channel doesn complete in time before the 2nd channel
begins initialization.

733482e445 [PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reason
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.

quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`

search pattern:
/UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h

8c65b4a604 [PATCH] fix remaining missing includes
Fix more include file problems that surfaced since I submitted the previous
fix-missing-includes.patch.  This should now allow not to include sched.h
from module.h, which is done by a followup patch.

4e57b68178 [PATCH] fix missing includes
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.
