This patch from Christoph Hellwig removes the kiobuf/kiovec
infrastructure.

This affects three subsystems:

video-buf.c:

   This patch includes an earlier diff from Gerd which converts
    video-buf.c to use get_user_pages() directly.

   Gerd has acked this patch.

LVM1:

   Is now even more broken.

drivers/mtd/devices/blkmtd.c:

   blkmtd is broken by this change.  I contacted Simon Evans, who
   said "I had done a rewrite of blkmtd anyway and just need to convert
   it to BIO.  Feel free to break it in the 2.5 tree, it will force me
   to finish my code."

Neither EVMS nor LVM2 use kiobufs.  The only remaining breakage
of which I am aware is a proprietary MPEG2 streaming module.  It
could use get_user_pages().

From Anton Blanchard.  This fixes a couple of Linux Test Project
failures.

- Returns EBUSY if the caller is trying to invalidate memory which is
  covered by a locked vma.

  The open group say:

  [EBUSY]
          Some or all of the addresses in the range starting
          at addr and continuing for len bytes are locked,
          and MS_INVALIDATE is specified.

- Returns EINVAL if the caller specified both MS_SYNC and MS_ASYNC

  [EINVAL]
          The value of flags is invalid.

  and:

          "Either MS_ASYNC or MS_SYNC is specified, but not both."

CONFIG_LBD was initially hardwired to "on" for testing.  That seems to
have gone OK, so now make it configurable.

From Bill Irwin: ensure that the data structures which hold the node's
zone structures is all zeroed before we start using it.

If you're peforming 512-byte sized IOs.  With, say,

	dd of=/dev/raw/raw1 bs=512

then the `pgpgin' and `pgpgout' accounting just sits on zero.

This is because it counts in kbytes, and 512/1024 is zero.

So change it to count sectors, and divide that by two when we report it
to userspace.

From Ed Tomlinson, then mauled by yours truly.

The current shrinking of the dentry, inode and dquot caches seems to
work OK, but it is slightly CPU-inefficient: we call the shrinking
functions many times, for tiny numbers of objects.

So here, we just batch that up - shrinking happens at the same rate but
we perform it in larger units of work.

To do this, we need a way of knowing how many objects are currently in
use by individual caches.  slab does not actually track this
information, but the existing shrinkable caches do have this on hand.
So rather than adding the counters to slab, we require that the
shrinker callback functions keep their own count - we query that via
the callback.

We add a simple registration API which is exported to modules.  A
subsystem may register its own callback function via set_shrinker().

set_shrinker() simply takes a function pointer.  The function is called
with

	int (*shrinker)(int nr_to_shrink, unsigned int gfp_mask);

The shrinker callback must scan `nr_to_scan' objects and free all
freeable scanned objects.  Note: it doesn't have to *free* `nr_to_scan'
objects.  It need only scan that many.  Which is a fairly pedantic
detail, really.

The shrinker callback must return the number of objects which are in
its cache at the end of the scanning attempt.  It will be called with
nr_to_scan == 0 when we're just querying the cache size.

The set_shrinker() registration API is passed a hint as to how many
disk seeks a single cache object is worth.  Everything uses "2" at
present.

I saw no need to add the traditional `here is my void *data' to the
registration/callback.  Because there is a one-to-one relationship
between caches and their shrinkers.


Various cleanups became possible:

- shrink_icache_memory() is no longer exported to modules.

- shrink_icache_memory() is now static to fs/inode.c

- prune_icache() is now static to fs/inode.c, and made inline (single caller)

- shrink_dcache_memory() is made static to fs/dcache.c

- prune_dcache() is no longer exported to modules

- prune_dcache() is made static to fs/dcache.c

- shrink_dqcache_memory() is made static to fs/dquot.c

- All the quota init code has been moved from fs/dcache.c into fs/dquot.c

- All modifications to inodes_stat.nr_inodes are now inside
  inode_lock - the dispose_list one was racy.

Cleaning out my queue of most minor patches:

  - Provides some kerneldoc for 'struct usb_interface' now that
    the API is highlighting it.

  - Fixes usb_set_interface() so it doesn't affect other interfaces.

    This provides the right place for an eventual HCD call to clean
    out now-invalid records of endpoint state, and also gets rid of
    a potential SMP issue where drivers on different interfaces
    calling concurrently could clobber each other.  (Per-interface
    data doesn't need locking except against config changes.)

  - It's OK to pass URB_NO_INTERRUPT hints if you're queueing a
    bunch of interrupt transfers.

The set_interface call should eventually take the interface as a
parameter, it's one of the few left using the "device plus magic
number" identifier.  I have a partial patch for that, but it doesn't
handle the (newish) ALSA usb audio driver or a few other callers.

Thanks to David Brownell for pointing this out to me.

Here is patch which adds parallel link cable support for Texas Instruments
graphing calculators.

Keep the partition information around for the lifetime of the module.

This updates AFS mtd partition parsing to the current CVS version:
- Don't recognise the AFS SIB as a partition
- Ensure initialisation of afs mtdpart structures.

We removed asm/mach-types.h from asm/hardware.h.  This means we must
now include asm/mach-types.h where its used.

We also fix h3600 pcmcia initialisation/cleanup.

Traditionally, the Assabet reverses its mapping of UART1 and UART3
when the Neponset board is connected.  This can be (a) confusing
and (b) annoying when the boot loader uses UART1.  We therefore
have a fixed mapping between the ttySA names and the physical
UARTs on this platform.

The patches convert drivers/pcmcia to use C99 named initializers,
and all the patches are against 2.5.42. There are 25 patches in
total, and the "cat"ing them together they're more that 20K, so
I'm sending the patches as a compressed attachment. The patches
were CC'd to Linus in the first mail that bounced.

Here's a small set of patches that switch the code to use C99
desiginated initializers. Patches are against 2.5.42.

Prevent the assembler putting constant pools in the middle of code.
Clean up shark ISA PIC handling.

This cset removes the global irq handling in the AcornSCSI driver,
and makes the target type for bitops an unsigned long array rather
than an unsigned char array.

Remove unnecessary use of __inline__, and remove a few unnecessary
prototypes.  copy_buffer is moved before use.

This removes a compilation warning and makes the code smaller.
It is also more obvious what's going on.

The USB gadget code now lives in arch/arm/mach-sa1100/usb, and
isn't in a mergable state.  We remove the old makefile entries
which are never going to be satisfied, and leave a placeholder for
the usb directory.

dump_stack() got used by the generic code.  Call our version
__dump_stack since we're running out of other descriptive names.
Allow show_trace_task to show the backtrace for the current
thread.

Add rudimentary support for Thumb ptracing; we aren't able to single
step through thumb branches yet, but this change provides enough
infrastructure to make this possible.

This cset updates (as much as is possible) the NCR5380-based Acorn
SCSI drivers, mainly converting them to the new error handling code.
However, they still don't build due to errors in NCR5380.

Vojtech has patches that bring their counterparts in the input
subsystem up to date (and into a working state) so these drivers
are no longer required.

This cset also fixes the Acorn i2c RTC code.

This cset combines the Atomwide and The Serial Port 16550 driver
modules into one "8250_acorn.c" driver.  This new module takes full
advantage of the LDM-based expansion card facilities.

This cset implements validity checks on the ethernet MAC address when
the device is opened, and refuses to open the device if this check
fails.  We also provide the set_mac_address method to allow ifconfig
to change the mac address to something valid.

In addition, the driver is converted from the old expansion card
discovery methods to the new device model driver framework.

Provide LDM-based driver registration/removal interface for drivers
to use.  We make the old device discovery code ignore devices
claimed via the LDM framework.  However, the LDM framework ignores
devices that may be in use by the old device discovery code.  This
is fine since the only devices that will still use the old discovery
code will be SCSI drivers.

Currently, we don't provide a useful dev.name entry.

This updates the Integrator cpufreq code to use the new interfaces,
and makes the sa1100 cpufreq round up the requested frequency.

The second serial port is never present in these machines, so its
pointless listing it in the first place.

- ide_register_hw takes two arguments, not one.
- ide_fix_driveid is no longer used.
