[-next] staging/vme: various fixes + new driver model for VME

["Emilio G. Cota" <cota@braap.org>]

Hi Greg,

This contains first a whole bunch of fixes to the existing vme
code in staging, to then introduce a new driver model for VME
in patch 27.

I have a short list of things to do after this patchset gets
reviewed:

- provide a saner API for VME drivers that just want to
  map/unmap chunks of memory (knowing nothing about underlying
  hardware features, such as windows). This is already
  implemented in the out-of-tree driver in [1].

- Make DMA work on the tsi148 (it's the only bridge I've got).
  This will probably involve changing or extending the
  current API.

- Test the whole thing with real hardware and a real VME driver
  (currently out of tree as well, see [2]), which I'll try
  to get merged, too--currently we just have vme_user.c which
  really isn't a kosher driver.



Note that the appended applies on top of linux-next.

The patchset can be pulled from:

Thanks,

                Emilio
