It needs s/malloc.h/slab.h/ .
It also forgets to free some memory on an error exit patch.
Patch for 2.5.39 follows.

Here are the scatterlist primitives there's been mail about before.
Now the code has passed basic sanity testing, and is ready to merge
into Linus' tree to start getting wider use.  Greg, please merge!

To recap, the routines are a utility layer packaging several usb
core facilities to improve system performance.  It's synchronous.
The code uses functionality that drivers could use already, but
generally haven't:

    - Request queueing.  This is a big performance win.  It lets
      device drivers help the hcds avoid wasted i/o bandwidth, by
      eliminating irq and scheduling latencies between requests.  It
      can make a huge difference at high speed, when the latencies
      often exceed the time to handle each i/o request!

    - The new usb_map_sg() primitives, leveraging IOMMU hardware
      if it's there (better than entry-at-a-time mapping).

    - URB_NO_INTERRUPT transfer flag, a hint to hcds that they
      can avoid a 'success irq' for this urb.  Only the urb for
      the last scatterlist entry really needs an IRQ, the others
      can be eliminated or delayed.  (OHCI uses this today, and
      any HCD can safely ignore it.)

The particular functionality in these APIs seemed to meet Matt's
requirements for usb-storage, so I'd hope the 2.5 usb-storage
code will start to use these routines in a while.  (And maybe
those two scanner drivers: hpusbscsi, microtek.)

Brief summary of testing:  this code seems correct for normal
reads and writes, but the fault paths (including cancelation)
haven't been tested yet.  Both EHCI and OHCI seem to be mostly
OK with these more aggressive queued loads, but may need small
updates (like the two I sent yesterday).  Unfortunately I have
to report that UHCI and urb queueing will sometimes lock up my
hardware (PIIX4), so while we're lots better than 2.4 this is
still a bit of a trouble spot for now.

I'll be making some testing software available shortly, which
will help track down remaining HCD level problems by giving the
queuing APIs (and some others!) a more strenuous workout than
most drivers will, in their day-to-day usage.

Greg, attached is a patch designed for diagnostic purposes.  Please apply
to the 2.5 tree -- yes, we'll be removing this at some point in the future.

It appears that we have a problem clearing halts.  This patch causes a very
clear message to be printed whenever a usb_stor_clear_halt() manages to
work.  So far, I haven't seen such a thing happen.  And I've seen _lots_ of
STALL conditions.

This problem has likely been around for a while... however, it hasn't been
noticed before because usb-storage was difficult to use because of other
bugs.  Heck, the most recent 'bk pull' is the first one for me in _months_
which let me boot all the way into X11.

I'm going to hold my patch queue until this is resolved.  On my test setup,
it's easy to see this failing.  I've tried with 4 different devices, with
both UHCI and EHCI drivers.  I don't want to confuse this problem with
other patches...

'result' in this function always seems to be -32.  Which is odd, because
control endpoints shouldn't do that.

I'm open to suggestions as to where to look for this bug, but my instincts
are telling me that this is a core or HCD issue, not a usb-storage issue.

On a positive note, this means that the error-recovery system gets a good
workout.

This corrects spelling mistakes, adds missed configuration for
cpufreq, corrects free_irq comment, etc.

Add "IRQ_" prefix to these sa1111 irq numbers.

We must clear down all currently pending IRQs before servicing any
IRQ on the chip.  This prevents immediate recursion into the
interrupt handling paths when we service the first IRQ.

This cset updates sa1100 code for the now merged cpufreq next-gen.

Update sa1100fb for recent fbcon changes, and move stork LCD power
handling into machine specific file.

This didn't follow the LDM model correctly.  The SA1111 is always
a device on the root bus.

This cset updates the SA1111 core, PCMCIA, OHCI and keyboard drivers,
allowing them to take advantage of the Linux device manager code;
this implements initial suspend/resume support for the SA1111 in the
core.  Many existing drivers currently rely on the old PM-based
interface for suspend/resume support.

In a test where some memory corruption happened, I noticed an
oops (null pointer exception in_irq) that's avoidable.  Here's
a patch that avoids it ... anyone seeing the err() is likely
to hang some process, but that's better than the alternative.
(Also inlines some used-once routines, saving a bit of space
to make up for the new diagnostic.)

In doing some more extensive testing of the urb queueing behavior,
I noticed that (a) IOC wasn't always being set for each urb, while
for now it needs to be set; (b) a qh patchup wasn't done quite
where it should be.  This resolves those two issues, as well
as making it a bit less noisy to unlink lots of urbs at the once.

This has minor usbcore cleanups:

DOC:
    - the changes passing a usb_interface to driver probe() and disconnect()
      weren't reflected in their adjacent docs.  likewise they still said
      it was possible to get a null usb_device_id (no more).

    - the (root) hub API restrictions from rmk's ARM patch weren't
      flagged

    - mention the non-dma-coherent cache issue for usb_buffer_alloc()

    - mention disconnect() cleanup issue with usb_{control,bulk}_msg()
      [ you can't cancel those urbs from disconnect() ]

CODE
    - make driver ioctl() use 'usb_interface' too ... this update
      also resolves an old 'one instance per device' bad assumption

    - module locking on driver->ioctl() was goofy, kept BKL way too
      long and didn't try_inc_mod_count() like the rest of usbcore

    - hcd unlink code treated iso inappropriately like interrupt;
      only interrupt still wants that automagic mode

    - move iso init out of ohci into shared submit_urb logic

    - remove interrupt transfer length restriction; hcds that don't
      handle packetization (just like bulk :) should be updated,
      but device drivers won't care for now.

/sbin/hotplug is now called when any device is added or removed from the
system.

In two drivers a wrong size of memory was allocated for cpufreq_driver: as
it must include NR_CPUS times a struct cpufreq_policy (and not struct
cpufreq_freqs). Thanks to Petr Vandrovec for this patch.

QDIO_BH was never actually used anyway, and won't do much good now BHs
are gone.

Beginning of proper refcounting.  New helpers introduced, several drivers
switched to using them for dynamic allocation of gendisks.  Once everything
is switched (and that will be way easier than per-drive gendisks series)
we will be able to add sane reference counts on gendisk, at which point
we can safely put pointer to gendisk in struct block_device / struct request
and we had pretty much won - from that point it's pretty straightforward
crapectomy in drivers.

char *major_name replaced with char disk_name[16];  All uses of ->major_name
replaced with those of ->disk_name and (obviously) simplified big way.  Bunch
of arrays, kmallocs, etc. is gone.

... now it can be done.  We also drop almost all arguments - there is only
one caller and everything is determined by the first argument.

Cleans the handling of partitioning up.  More or less the same story as with
other drivers...

corrected handling of sizes.  Ugh.

get_gendisk() now takes dev_t (instead of kdev_t) and gets an additional
argument - int *part.  Set to 0 for non-partitioned, partition number
for partititoned.  Callers updated.  Yes, I hate passing return values
that way ;-/  We need that since old "minor(dev) - disk->first_minor"
doesn't work for stuff with non-trivial numbers (e.g. floppy) and
get_gendisk() really has to return both gendisk and partition number.
Fortunately, amount of callers of gendisk() is about to drop RSN big way...

The list used to generate /proc/partitions turned into list_head one;
we also restore the old order of elements (originally we added to the end
of list; recent changes had reverted that, now we are back to original
order).

Make IDE set the dma mask to full 32-bit dma.

Just for niceness, loop should clear queue queuedata when it exits.
