Doug Chapman 29982e9acd [SCSI] fusion: fix for BZ 8426 - massive slowdown on SCSI CD/DVD drive
Patch for: http://bugzilla.kernel.org/show_bug.cgi?id=8426

A recent code cleanup that moved code from mptscsih to mptspi
inadvertently change the order some code was called.  This caused
a massive slowdown (of 150x to 300x) on the CD/DVD drive on the
high-end HP Integrity servers.

Eric Moore 7297824581 [SCSI] fusion: fix domain validation loops
After host reset, the device are programmed to default asyn narrow nego.
We need to reprogram the parameter back to previous values.  If the host
reset is called as a result of spi_dv_device() commands timing out, its
possible to get into an infinite loop of dv to host reset.  This will
prevent that case, as we merely program old values.  If host reset is
called outside context of domain validation, then we can  call
spi_dv_device.

Vasily Averin d1985ad1da [PATCH] i2o: block IO errors on i2o disk
I2O subsystem has been broken in mainstream several months ago (after
2.6.18).  Commit 4aff5e2333 from Jens
Axboe split struct request ->flags into two parts: cmd_type and
cmd_flags.

In i2o layer this patch has replaced flag REQ_SPECIAL by the according
cmd_type.  However i2o has used REQ_SPECIAL not as command type but as
driver-specific flag for the debug purposes.  As result all i2o requests
have type "special" now, are not processed to the hardware and fail with
I/O error:

   i2o/hda:<3>Buffer I/O error on device i2o/hda, logical block 0
  Buffer I/O error on device i2o/hda, logical block 0
  Buffer I/O error on device i2o/hda, logical block 0
   unable to read partition table
  block-osm: device added (TID: 207): i2o/hda

The following patch removes the extra debug checks without any drawbacks and
restores the normal driver's work.

Eric Moore ad8c31bb69 [SCSI] fusion: remove VMWare guest OS remounted as read only work around
This address the issue of VMWare guest OS being remounted as read-only
becuase the underlying device was held busy too long and at the
same time address Engenio MPP driver concerns over infinite retries.
This patch removes the code that snoops the SAM STATUS on busy, which
would be returning DID_BUS_BUSY, instead we return the status as is.
Retry hanlding seems to be properly handled in scsi_softirq_done,
where a busy sam status would only occurr for the time specified by
(cmd->allowed +1) * cmd->timeout_per_command.

Horms b364fd5081 [SCSI] fusion: honour return value of pci_enable_device() in mpt_resume()
Honour the return value of pci_enable_device(), which
seems to be a desirable thing to do:

  2.6.20-rc4
  gcc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)

    CC [M]  drivers/message/fusion/mptbase.o

    drivers/message/fusion/mptbase.c:1541: warning: ignoring return value
    of `pci_enable_device', declared with attribute warn_unused_result

It also in turn has mptscsih_resume() honour the return value of
mpt_resume()

I'm not sure about the handling of the other potential error cases
in mpt_resume(), of which there appear to be many. But this does
seem to be a good start.

Judith Lebzelter ba76ef2460 [SCSI] mptsas: Fix oops for insmod during kexec
This fix's an oops during driver load time.   mptsas_probe calls
mpt_attach(over in mptbase.c).  Inside that call, we read some
manufacturing config pages to setup some defaults.  While reading the
config pages, the firmware doesn't complete the reply in time, and we
have a timeout. The timeout results in hardreset handler being called.
The hardreset handler calls all the fusion upper layer driver reset
callback handlers.  The mptsas_ioc_reset function is the callback
handler in mptsas.c.   So where I'm getting to, is mptsas_ioc_reset is
getting called before scsi_host_alloc is called, and the pointer ioc->sh
is NULL as well as the hostdata.

Tim Schmielau cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
	done

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.

Ralf Baechle d78437245a [PATCH] i2o_exec_exit and i2o_driver_exit should not be __exit.
i2o_exec_exit and i2o_driver_exit were marked as __exit which is a bug
because both are invoked from __init and __exit functions.

Jeff Garzik 3889b26beb [PATCH] I2O: more error checking
i2o_scsi: handle sysfs failure

i2o_device:
 * convert i2o_device_add() to return integer error code
   rather than pointer.  Fortunately -nobody- checks the return code of
   this function, so changing has nil impact.
 * handle errors thrown by device_register()

More work in i2o_device remains.

Christoph Lameter e18b890bb0 [PATCH] slab: remove kmem_cache_t
Replace all uses of kmem_cache_t with struct kmem_cache.

The patch was generated using the following script:

	#!/bin/sh
	#
	# Replace one string by another in all the kernel sources.
	#

	set -e

	for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do
		quilt add $file
		sed -e "1,\$s/$1/$2/g" $file >/tmp/$$
		mv /tmp/$$ $file
		quilt refresh
	done

The script was run like this

	sh replace kmem_cache_t "struct kmem_cache"
