Thanks, I've removed it from my branch.  (Since it's a trivial update, I
won't repost the change on LKML unless I get any more feedback that needs
addressing.)

I've checked in support for a "sim_console" boot flag that modifies the
behavior of the tile-specific console driver to use the simulator output
facility instead.  I'll plan to push that to LKML with the next batch of
changes I post.
