TIMEOUT_VALUE was killed from blk.h and moved to drivers that need it (like this one)
DEVICE_REQUEST is also dead, so we init the queue with the driver request handler

Conversion done by William Irwin a good while ago.

Variant of a patch in 2.4 by Steven Whitehouse.

Originally from: Jeremy Elson <jelson@circlemud.org>

As per the old comment, this patch adds checking of the return
value of setup_arg_pages() and aborts cleanly. From 2.4
(also a missing GPL tag)

Stale cruft, and what looks like a merge error.

Allow user to define the upper limit of number of interrupts generated

Should allow for things like adjusting readahead on raw devices.

Patch from 2.4 sets the maximum size of the queue in a more sensible manner

region handling cleanups

o check request_region result
o handle failure gracefully

o printk levels
o check_region -> request_region cleanups
o allocated region releasing on failure

simple region handling cleanups.

o Check misc_register return code
o request_region() return code checking
o graceful failure

o Check request_region result

o check request_region result
o Handle failure gracefully

Wow, someone found some new devices for this beast..

checks return codes, and sanitises resource allocation.

o  mention a quirk in the athlon smp detection
o  mark some use-once paths as __init

The usual check_region -> request_region work, plus freeing
of resources on failure path.

Odd, this is the missing half of the recent fix where we prefetched
too far. Not sure how this bit got dropped. Without it, we still prefetch
past the end of a range of memory.
Also small compiler hint microoptimisations

The following should allow the affected architectures to build in
2.5.19 as currently there will be two definitions of
copy_siginfo_to_user and if an architecture defines its own
siginfo_t it MUST define copy_siginfo().

This patch from Laurent Latil <laurent@latil.nom.fr> fixes a copy
and paste error.

 - Since Bartek has released finally an entierly user space based setup
   monitoring utility, we can finally remove the nonfunctional PROC code from
   the host chip drivers. We have preserved it thus far only for documentation
   purposes.

 - Use generic bus master DMA setup code. There is nothing wrong with it.

 - Make the ide-scsi code actually just allow for one device id per scsi host,
   since we are registering a host per device right now.  This prevents the
   repetitive device recognition. Well registering an SCSI host of every single
   disk out there isn't the proper thing to do. I will deal with that later
   after my visual perception recovers again from already looking too long at
   the SCSI code :-).

 - Deal properly with host specific data mapping. (Could be that solves some
   problems with the driver, which where in reality kernel data corruptions.)

 - Homogenize flag handling for ATAPI drivers.

device model: Use driver_for_each_dev to unbind drivers from its devices (now that it's implemented)

- iterate over all devices a driver has, with proper locking on driver and refcounting on devices
