add missing dev_put in dev_ifname32
fix usbdevfs (from sparc64)
add SG_IO (from sparc64)
add tun, vlan and random device ioctls

- Streamline the usage of sector_t over the strategy routines in question a
   bit. Streamline the do_request code in ide-disk.c.

- Improve the readability of start_request in ide.c.

- Remove obsolete/nowhere used stuff from hdreg.h.

- Splitup special_t into classical flag field.

- Use only a single field to determine the capacity of a drive.  Make this
   field and the code paths it follows as far as possible use the sector_t
   instead of a hard coded integer types.  This increases the chances that at
   some distant point in time we will indeed be able to use 64 bit wide sector_t
   entities. (Disks are getting huge those times now...)

- Initialise the per-request_queue readahead parameter properly,
  rather than the dopey "if it's zero you get the deafult"
  approach.

- Permit zero-length readahead.

- 80-columnify mm/readahead.c

Get rid of traces of the old-style ALL_MOBJS variable.

This also fixes the following issue, which could cause a warning with
certain configs:

Makefiles (legally) do:

obj-$(CONFIG_SND_AD1848) += snd-pcm.o snd-timer.o snd.o
obj-$(CONFIG_SND_CS4231) += snd-pcm.o snd-timer.o snd.o snd-rawmidi.o

so when the first option is set to y, the second to m, we have e.g.
snd-pcm.o on both $(obj-y) and $(obj-m). We correctly don't build
the modular version in this case.

However, if snd-pcm.o was a multi-part object, we did automatically
generate a link rule for both the modular and the built-in version, 
which caused a warning - that's now fixed.

 - switch md_error() to struct block_device * - just cleaning up
   after ->bi_dev switch.

 - bdevname() switched to struct block_device *.  Old variant (taking
   kdev_t) renamed to __bdevname() (very few callers remain).  This
   allow to drop ->b_dev conveniently - it's duplicated by ->b_bdev
   and most of remaining users were bdevname(bh->b_dev) in various
   places.

 - *NOW* all places that (re)assign ->bi_dev have relevant struct
   block_device *.  ->bi_bdev (struct block_device * equivalent of
   ->bi_dev) introduced, ->bi_dev removed, users updated.

 - block/loop.c - switch ->lo_device to struct block_device *.

 - (JFS) removes ->dev from struct jfs_log - it's duplicated by
   ->bdev.  Old users of ->dev updated.

 - md/linear.c - bring struct block_device * into private data.

 - this one is interesting and will play in the next series as well;
   affected place is fs/block_dev.c::do_open().  We check if bdev is
   a partition (same way it is done in generic_make_request()) and
   if it is - open entire disk and put pointer to its bdev into a
   new field bdev->bd_contains.  Otherwise (non-partition) we
   set bdev->bd_contains to bdev.  Corresponding cleanup done in
   blkdev_put() (and failure path in do_open()) - when the last opener
   goes away we close bdev->bd_contains if bdev is a partition (i.e.
   not equal to its ->bd_contains) and set it to NULL.
   Immediate effect is that we can get from bdev of partition to
   bdev of disk when submitting a bio, but it also opens a way
   to handle partition-parsing in a sane way.  That will be done
   in the next series.

 - md/raid1.c - bring struct block_device * into private data.

 - md/multipath.c convert to bio, compile fixes, bring struct
   block_device * into private data.

 - switch loop_set_fd() to struct block_device

 - switch blk_{get,set}_readahead() to struct block_device *

 - switch block_ioctl() to struct block_device *

 - new helpers: queue_hardsect_size() and bdev_hardsect_size().  Analogous
   to get_hardsect_size() for queue and struct block_device * respectively
   Most of get_hardsect_size() callers converted to these.

 - remove abuses of blksize_size[] and (late) hardsect_size[].  Mostly
   drivers/s390/char/*, BTW...
