This is a complete rewrite of the LDM driver (support for Windows
Dynamic Disks).  It incorporates Al Viro's recent partition handling
tidy ups.

Details:
  LDM Driver rewritten.  More efficient.  Much smaller memory footprint.

  The old driver was little more than a stopgap.
  The new driver is a complete rewrite
  based on a much better understanding of the database
  based on much more reverse engineering
  more able to spot errors and inconsistancies
  it has a much smaller memory footprint
  no longer considered experimental
  accompanied by brief info: Documentation/ldm.txt

On a ppc64 machine running 2.5.28 we were hitting this BUG in
__free_pages_ok:

BUG_ON(page->pte.chain != NULL);

In pte_chain_lock we use test_and_set_bit which implies a memory
barrier. In pte_chain_unlock we use clear_bit which has no memory
barriers so we need to add one.

Here's a patch from Christoph Hellwig and myself to supply write->read
semaphore downgrade, and also from Brian Watson to supply trylock for rwsems.

Make sure the cpu argument to cpu_online() is evaluated for
side effects on UP too.

Things look rather like this..

values on input devices. This is something the X peoople
really wanted.
Rename input_devinfo to input_id, it's shorter and more 
to the point.
Remove superfluous printks in uinput.c
Clean up return values in evdev.c ioctl. 

comes to directions of movement and rotation, a mouse wheel should
be positive where it "rotates forward, away from the user". We had
the opposite in psmouse.c. Fixed this.

converter to atkbd.c - trivial. Remove ps2serkbd, because it's
not needed anymore.

input struct to userspace.

EV_SYN. Touches every input driver. The first to make use of it
is mousedev.c to properly merge events into PS/2 packets.

Update for removed global irq lock

Rediffed with the 2.5.28 biosparm change included

irq can be -1 if the card errors during config. synchronize_irq(-1) looks
bad

The Q40 keyboard is only found on a Q40..

Event is just used for internal flags and with set_bit for atomicity. This
kills the warning the obvious way

when the host driver detects a parity or framing error, we can ask the
keyboard to resend the data, instead of treating random garbage as
valid data.
We also export serio_interrupt() - serio modules are using it, yet you
can't use them as modules without this symbol exported.

layer client, but this final patch will be _very_ small now :-)).
