d9a9cdfb07 [PATCH] sysfs and driver core: add callback helper, used by SCSI and S390
This patch (as868) adds a helper routine for device drivers that need
to set up a callback to perform some action in a different process's
context.  This is intended for use by attribute methods that want to
unregister themselves or their parent device.  Attribute method calls
are mutually exclusive with unregistration, so such actions cannot be
taken directly.

Two attribute methods are converted to use the new helper routine: one
for SCSI device deletion and one for System/390 ccwgroup devices.

23d046f43a [ARM] ARM SCSI: Don't try to dma_map_sg too many scatterlist entries
An off-by-one bug meant we were always trying to map one too many
scatterlist entries.  This was mostly harmless prior to the checks
going in to consistent_sync(), but now causes the kernel to BUG.

Also, powertec.c was missing an assignment to info->ec.

there's a USB mass storage device which exists in two version. One

when LUN-0 reports a scsi_level of 0; the LUN bits will no longer be set

it's possible that some wacky device might be adversely affected.  I doubt

e423ee31db [SCSI] scsi_scan.c: handle bad inquiry responses
A particular USB device has been reporting short inquiry lengths.  The
SCSI code cannot operate properly unless we get an inquiry length of
36 or above (because of the way we parse vendor and product), so
assume at least 36 bytes are valid even if the device reports fewer.
This is wrong, but it's no worse than what we're doing now (using the
garbage beyond the last reported valid byte).

The sequencer firmware file has both a string (currently showing
V17/10c6) and a number (currently set to 1.1).  It has become apparent
that Adaptec may issue sequencer firmware in the future which could be
incompatible with the current driver.  Therefore, the driver will be
tied to the particular major number of the firmware (i.e. the current
driver will load any 1.x firmware).  Additionally, the driver will print
out both the ascii string and the major number, so with this pach the
current firmware will print out

930e99bd13 [SCSI] tgt: fix the user/kernel ring buffer interface
This patches fixes two bugs in the scsi target infrastructure's
user/kernel interface.

- It wrongly assumes that the ring buffer size of the interface (64KB)
is larger than or equal to the system page size. This patch sets the
ring buffer size to PAGE_SIZE if the system page size is larger.

- It uses PAGE_SIZE in the header file exported to userspace. This
patch removes it.

8f3334edae [SCSI] sgiwd93: interfacing to wd33c93
1) sgiwd93 used to switch off asynchronous mode on the wd33c93, discarding
   any "nosync"-requests from the commandline.
   But we need to allow "nosync"-requests for selected devices, for example
   the Pioneer DVD305S.
   (For the curious: this device accepts the SDTR from wd33c93 and success-
   fully sends inquiry data in sync mode, but after the data phase in the
   inquiry command does an unexpected disconnect, seemingly sending no
   "status" or "command complete". Forcing async transfers makes it work
   together flawlessly with the wd33c93. Of course, preferable would be, to
   implement wd33c93's "resume command" stuff, but that probably will not
   come soon.)

2) Maximize benefit from the preceding Fast SCSI patch for wd33c93 by passing
   the higher input-clock frequency explicitely. To be applied after the
   mentioned wd33c93 patch.

a5d8421b2f [SCSI] wd33c93: Fast SCSI with WD33C93B
Attached are patches, which help to utilize more of the WD33C93B SCSI
controller's capabilities.

1) Added/changed all the necessary code to enable Burst Mode DMA. Only
   Single Byte DMA was used before.

2) Added/changed all the necessary code to enable Fast-10 SCSI transfers.

3) The original driver inadvertently used a transfer period of 1000-800ns
   (the lowest possible transfer rate) for asynchronous data transfers,
   instead of the (configurable) default period intended for this purpose,
   if the target responded to a SDTR not with a Reject-message, but with
   a zero-SDTR. This issue was fixed.
   Moreover, in case of a Reject the driver used the default-period's
   initialization-value instead of its (maybe smaller) current value. The
   missing assignment was added.

4) The driver's commandline- and proc-file-interface was augmented to
   handle the new options properly.

The WD33C93 manual, found at
http://www.datasheet.in/datasheet-html/W/D/3/WD33C93B_WesternDigital.pdf.html,
was very helpful.

0b4d414714 [PATCH] sysctl: remove insert_at_head from register_sysctl
The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name.  Which is
pain for caching and the proc interface never implemented.

I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.

So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

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).

c376222960 [PATCH] Transform kmem_cache_alloc()+memset(0) -> kmem_cache_zalloc().
Replace appropriate pairs of "kmem_cache_alloc()" + "memset(0)" with the
corresponding "kmem_cache_zalloc()" call.

19966769f9 [SCSI] aic79xx: use dma_get_required_mask()
As originally noted by Frederic Temporelli, the aic79xx supports 64
bit addressing, but the initialization code of the driver is wrong: it
tests the available memory size instead of testing the maximum
available memory address.

This patch uses the correct dma_get_required_mask() macros to
determine the correct addressing method.

4df4db5c6c [TC] dec_esp: Driver model for the PMAZ-A
This is a set of changes that converts the PMAZ-A support to the driver model.

The use of the driver model required switching to the hotplug SCSI
initialization model, which in turn required a change to the core NCR53C9x
driver.  I decided not to break all the frontend drivers and introduced an
additional parameter for esp_allocate() to select between the old and the new
model.  I hope this is OK, but I would be fine with converting NCR53C9x to the
new model unconditionally as long as I do not have to fix all the other
frontends (OK, perhaps I could do some of them ;-) ).
