[GIT PATCH pata-2.6] ide: clean up ide-tape, take#2

[Tejun Heo <tj@kernel.org>]

Hello, Bartlomiej, Jens, Borislav.

Upon ack, please pull from the following git tree.

  git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git ide-phase2

This is the second take of clean-up-ide-tape patchset.  Please read
the head message on the last take[L] for general description.

Changes from the last take are

* Tested with Seagate STT8000A rev 5.44 and various fixes bugs
  including a few already existing ones.

* 0003 and 0004 of the last take are merged into one.  The first one
  converted data carrier to bio and the second changed data transfer
  mechanism accordingly.  As blk_rq_map_kern() can produce scatter IO
  the first one without the second didn't work.

* Rebased.

 0001-ide-tape-floppy-fix-failed-command-completion-after.patch
 0002-ide-atapi-tape-floppy-allow-pc_callback-to-chan.patch
