Kashyap, Desai bcfe42e980 [SCSI] mptfusion: Fix Incorrect return value in mptscsih_dev_reset
There's a branch at the end of this function that
is supposed to normalize the return value with what
the mid-layer expects. In this one case, we get it wrong.

Also increase the verbosity of the INFO level printk
at the end of mptscsih_abort to include the actual return value
and the scmd->serial_number. The reason being success
or failure is actually determined by the state of
the internal tag list when a TMF is issued, and not the
return value of the TMF cmd. The serial_number is also
used in this decision, thus it's useful to know for debugging
purposes.

Kashyap, Desai 84857c8bf8 [SCSI] mptfusion: mptctl_release is required in mptctl.c
Added missing release callback for file_operations mptctl_fops.
Without release callback there will be never freed. It remains on
mptctl's eent list even after the file is closed and released.

Jesper Juhl 1dcb202f42 drivers/message/, i2o: Remove unnecessary casts of void ptr returning alloc function return values
The [vk][cmz]alloc(_node) family of functions return void pointers which
it's completely unnecessary/pointless to cast to other pointer types since
that happens implicitly.

This patch removes such casts from drivers/message/

Jeff Garzik f281233d3e SCSI host lock push-down
Move the mid-layer's ->queuecommand() invocation from being locked
with the host lock to being unlocked to facilitate speeding up the
critical path for drivers who don't need this lock taken anyway.

The patch below presents a simple SCSI host lock push-down as an
equivalent transformation.  No locking or other behavior should change
with this patch.  All existing bugs and locking orders are preserved.

Additionally, add one parameter to queuecommand,
	struct Scsi_Host *
and remove one parameter from queuecommand,
	void (*done)(struct scsi_cmnd *)

Scsi_Host* is a convenient pointer that most host drivers need anyway,
and 'done' is redundant to struct scsi_cmnd->scsi_done.

Minimal code disturbance was attempted with this change.  Most drivers
needed only two one-line modifications for their host lock push-down.

Arnd Bergmann 2a48fc0ab2 block: autoconvert trivial BKL users to private mutex
The block device drivers have all gained new lock_kernel
calls from a recent pushdown, and some of the drivers
were already using the BKL before.

This turns the BKL into a set of per-driver mutexes.
Still need to check whether this is safe to do.

    if grep -q 'include.*linux.mutex.h' ${file} ; then
            sed -i '/include.*<linux\/smp_lock.h>/d' ${file}

Arnd Bergmann c45d15d24e scsi: autoconvert trivial BKL users to private mutex
All these files use the big kernel lock in a trivial
way to serialize their private file operations,
typically resulting from an earlier semi-automatic
pushdown from VFS.

None of these drivers appears to want to lock against
other code, and they all use the BKL as the top-level
lock in their file operations, meaning that there
is no lock-order inversion problem.

Consequently, we can remove the BKL completely,
replacing it with a per-file mutex in every case.
Using a scripted approach means we can avoid
typos.

file=$1
name=$2
if grep -q lock_kernel ${file} ; then
    if grep -q 'include.*linux.mutex.h' ${file} ; then
            sed -i '/include.*<linux\/smp_lock.h>/d' ${file}
    else
            sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file}

Arnd Bergmann 6e9624b8ca block: push down BKL into .open and .release
The open and release block_device_operations are currently
called with the BKL held. In order to change that, we must
first make sure that all drivers that currently rely
on this have no regressions.

This blindly pushes the BKL into all .open and .release
operations for all block drivers to prepare for the
next step. The drivers can subsequently replace the BKL
with their own locks or remove it completely when it can
be shown that it is not needed.

The functions blkdev_get and blkdev_put are the only
remaining users of the big kernel lock in the block
layer, besides a few uses in the ioctl code, none
of which need to serialize with blkdev_{get,put}.

Most of these two functions is also under the protection
of bdev->bd_mutex, including the actual calls to
->open and ->release, and the common code does not
access any global data structures that need the BKL.

Kashyap, Desai c9de7dc483 [SCSI] mptfusion: Block Error handling for deleting devices or Device in DMD
Issue description:
In multipath topology, when device deletion is in transient state,
multipath driver can call blk_flush_queue() as part of path failure.
Before device get deleted from OS, Device may go OFFLINE as part of error
handling kicked off triggered from multipathing driver. Above condition hits
more frequently if device missing delay timer (which is LSI specific firmware
parameter) is non zero value.

root cause of this issue is Error handling thread is getting kicked off for
device which is not really present(in transient state of deleting).

This patch has solution for this issue. driver is now using eh_timed_out
callback. See below.

mptsas_transport_template->eh_timed_out = mptsas_eh_timed_out

Using mptsas_eh_timed_out function, driver can decide weather vdevice is
under Device missing delay or deleting state.

for either of those cases, there is BLK_EH_RESET_TIMER return to scsi mid
and error handling thread will not be kicked off for that particular scsi
command.

Kei Tokunaga 3e84beba60 [SCSI] mptsas: fixed hot-removal processing
This patch fixes mptsas disk hot-removal processing.  The
hot-removal processing doesn't complete because of this condition.

  drivers/message/fusion/mptsas.c:
  mptsas_taskmgmt_complete()

  if ((mptsas_find_vtarget(ioc, channel, id)) && !ioc->fw_events_off)
    mptsas_queue_device_delete(...);

mptsas_queue_device_delete(), which must be called for
hot-removal, never gets called because mptsas_find_vtarget()
always returns 0 here.  At that time, the vtarget has already
been freed in mptsas_target_destroy(), and also the scsi_device
has been marked as SDEV_DEL.

As a result of the issue, port deletion functions won't get
called and the device ends up being in an incomplete state.
(Some data structures and sysfs entries, which should be
removed in hot-removal, remain.)  One side effect of this is
that a hot-addition of the device (bringing the device back
on) fails.

This patch just removes mptsas_find_vtarget() from the if-state
condition.

Kashyap, Desai cc7e9f5f99 [SCSI] mptfusion: Added code for occationally SATA hotplug failure.
Issue: SATA hotplug does not work sometimes.
At the time of ADD device/ADD phys disk, drive may fail to add SATA device
due to temporary SAS Address for SATA device generated by firmware. Final
SAS address for SATA driver will be generated only after disk spinup is
done. This may take some times for slow spining SATA drives.

At phy link up driver gets attached device sas address and stores into
phyinfo. At the time of ADD event driver will read sas device page0 using
channel and FW ID provided in ADD Device event. Here in case of SATA drives,
driver will see miss match in phyinfo->sas_address and latest sas address
read from SAS DEVICE PAGE0 and eventually device won't be added to OS.

Fix:
When Driver read SAS DEVICE PAGE0, it can identify Device type looking at
device_info. If device is SATA drive and sas address mismatch happens,
Driver will do same stuffs which happened at the time of LINK UP to get
correct piece of information from Pages. ( Find parent device and refresh
parent device phys either HBA refresh/Exp refresh)

Ryan Kuester 2a1b7e575b [SCSI] mptsas: fix hangs caused by ATA pass-through
I may have an explanation for the LSI 1068 HBA hangs provoked by ATA
pass-through commands, in particular by smartctl.

First, my version of the symptoms.  On an LSI SAS1068E B3 HBA running
01.29.00.00 firmware, with SATA disks, and with smartd running, I'm seeing
occasional task, bus, and host resets, some of which lead to hard faults of
the HBA requiring a reboot.  Abusively looping the smartctl command,

    # while true; do smartctl -a /dev/sdb > /dev/null; done

dramatically increases the frequency of these failures to nearly one per
minute.  A high IO load through the HBA while looping smartctl seems to
improve the chance of a full scsi host reset or a non-recoverable hang.

I reduced what smartctl was doing down to a simple test case which
causes the hang with a single IO when pointed at the sd interface.  See
the code at the bottom of this e-mail.  It uses an SG_IO ioctl to issue
a single pass-through ATA identify device command.  If the buffer
userspace gives for the read data has certain alignments, the task is
issued to the HBA but the HBA fails to respond.  If run against the sg
interface, neither the test code nor smartctl causes a hang.

sd and sg handle the SG_IO ioctl slightly differently.  Unless you
specifically set a flag to do direct IO, sg passes a buffer of its own,
which is page-aligned, to the block layer and later copies the result
into the userspace buffer regardless of its alignment.  sd, on the other
hand, always does direct IO unless the userspace buffer fails an
alignment test at block/blk-map.c line 57, in which case a page-aligned
buffer is created and used for the transfer.

The alignment test currently checks for word-alignment, the default
setup by scsi_lib.c; therefore, userspace buffers of almost any
alignment are given directly to the HBA as DMA targets.  The LSI 1068
hardware doesn't seem to like at least a couple of the alignments which
cross a page boundary (see the test code below).  Curiously, many
page-boundary-crossing alignments do work just fine.

So, either the hardware has an bug handling certain alignments or the
hardware has a stricter alignment requirement than the driver is
advertising.  If stricter alignment is required, then in no case should
misaligned buffers from userspace be allowed through without being
bounced or at least causing an error to be returned.

It seems the mptsas driver could use blk_queue_dma_alignment() to advertise
a stricter alignment requirement.  If it does, sd does the right thing and
bounces misaligned buffers (see block/blk-map.c line 57).  The following
patch to 2.6.34-rc5 makes my symptoms go away.  I'm sure this is the wrong
place for this code, but it gets my idea across.

not doing complete process of mptsas_probe(). It will only make
sure IOC structure is created and IOC reference is available for

case of Target mode only mptsas. If we are removing IOC which is
only in Target mode, We should only detach IOC instead of

mode controller. Now For T mode controller, only part clean up is

needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

Michael Reed 03cb3829e0 [SCSI] fusion: hold off error recovery while alternate ioc is initializing
After discussing this patch with LSI, I resubmitting with a recommended
40 second wait for the alternate ioc's initialization to complete.
--
Fusion FC chips are two function with some shared resources.  During
initialization of one function its driver inhibits the ability of the
other function's driver to allocate message frames by clearing its
"active" flag.  Should mid-layer error recovery be initiated for a
scsi command during this initialization (which can take up to 40 seconds)
error recovery will escalate to the level of host reset.  This host
reset might fail (as the other function is resetting) resulting in
all connected targets being taken offline.

This patch holds off mid-layer error recovery for up to 40 seconds
to permit initialization of the other function to complete.

Anatolij Gustschin f1053a7ca9 [SCSI] mptsas: Fix issue with chain pools allocation on katmai
Since commit 9d2e9d66a3
mptsas driver fails to allocate memory for the MPT chain buffers
for second LSI adapter on PPC440SPe Katmai platform:
...
ioc1: LSISAS1068E B3: Capabilities={Initiator}
mptbase: ioc1: ERROR - Unable to allocate Reply, Request, Chain Buffers!
mptbase: ioc1: ERROR - didn't initialize properly! (-3)
mptsas: probe of 0002:31:00.0 failed with error -3

This commit increased MPT_FC_CAN_QUEUE value but initChainBuffers()
doesn't differentiate between SAS and FC causing increased allocation
for SAS case, too. Later pci_alloc_consistent() fails to allocate
increased chain buffer pool size for SAS case.

Provide a fix by looking at the bus type and using appropriate
MPT_SAS_CAN_QUEUE value while calculation of the number of chain
buffers.

Powerpc 44x uses 36 bit real address while the real address defined in
MPT Fusion driver is of type 32 bit. This causes ioremap to fail and
driver fails to initialize. This fix changes the data types

resource_size_t which is 64-bit. The driver has been tested, the disks

This patch modifies scsi_host_template->change_queue_depth so that
it takes an argument indicating why it is being called. This will be
used so that if a LLD needs to do some extra processing when

This is a simple port of the drivers setting a change_queue_depth

if the user was requesting it.
