This callback is required when RAM based devices are used as swap disks.
One such device is ramzswap which is used as compressed in-memory swap
disk.  For such devices, we need a callback as soon as a swap slot is no
longer used to allow freeing memory allocated for this slot.  Without this
callback, stale data can quickly accumulate in memory defeating the whole
purpose of such devices.

Added SWP_BLKDEV flag to distinguish block and regular file backed
swap devices. We could also check if a swap is entire block device,
rather than a file, by:
S_ISBLK(swap_info_struct->swap_file->f_mapping->host->i_mode)
but, I think, simply checking this flag is more convenient.

There are three minor changes I would like to do on my last patch:

* Comedi is formally not dependant on any hardware, e.g. it is possible
  to use comedi_test without (PCI || PCMCIA || PCCARD || USB || ISA)
* comedi_parport is not dependant on PARPORT_PC.
* indirect ni_mio_cs (16-bit PCMCIA) dependancy on mite PCI-chip may
  confuse users, thus changing COMEDI_NI_TIO depends on COMEDI_MITE
  to select COMEDI_MITE.

PC/104-drivers went into ISA,
PC/104+ went into PCI,
Drivers without a bustype went into "misc".
In doubt drivers supporting both ISA/PCI went into PCI.
Drivers without any detailed hardware info went into ISA, e.g. fl512.c
Some NI drivers are used by other NI drivers from different bustypes
are grouped seperately in NI_COMMON.

Currently, each ramzswap device can be assigned
a separate 'backing swap' file/partition. The ramzswap
driver forwards swap I/O requests to this backing swap
whenever an incompressible page is found.

This feature adds nearly 700 lines of code and it
also duplicates much of the swapon() functionality
(for example, finding swap extents and so on). Removing
this code makes the driver much simpler and should
help its transition from staging to stable drivers
area (drivers/block/).

Similar functionality may be implemented if we can
implement migrating pages across swap devices but the
details have not yet been worked out.

Support for _partitions_ as backing swap could be
retained as it requires a few lines of code only.
This part can be re-introduced later if above swap
migration method turns out to be infeasible.

More cleanups and code comments will be added soon.
