[dm-devel] dm: pass up rotational flag

[Martin K. Petersen]

Here's a tentative patch set for transitioning the non_rotational,
discard and secure discard queue flags to the topology information.

The first patch introduces a new function for setting the default limits
for stacking drivers like we discussed a few weeks ago.  Wrt. to naming
I felt it was best to have a function that said "stacking".  That's why
I introduced a new call instead of using blk_set_default_limits() even
though that function was originally motivated by device mapper.

The last two patches deal with non-rotational and the discard flags
respectively.

Let me know what you guys think...
