- fix non-debug build
- Use %"PRIx8", not %hx, for uint8_t.  %hx is for unsigned short.
- Flush unused function. Found by joerg.
- Make sure rbtrees are empty on desctruction.
  If related to PR kern/51076, might help catch the bug a bit earlier.
- revert rev 1.6.  we don't have access to those files as normal files
  and possible will get them directly elsewhere soon.
  (if i hack my nouveau to ignore fireware failure, it end up having
  a vaguely working console and slowly working X, which is better than
  the current situation.)
- Avoid possible null pointer dereference. Found by Coverity, CID 709895.
- Mark fallthrough to suppress Coverity complaints.
  CID 143119
  CID 143120
  CID 143121
  CID 143122
  CID 143123
  CID 143124
- Sanity-check that the encoder we found is not null.
  I think the previous code guarantees that finding this encoder should
  work, so this should be a moot point. CID 145720.
- Mark intended fallthrough to suppress Coverity CID 201378.
- Mark fallthrough with a comment to appease Coverity, CID 703385.
- Make it clearer to Coverity that there's no array overrun. CID 989067.
- Rework ttm tt swapin/swapout logic.
  Rather than handling `swapping in/out' here, per se, we let uvm do
  that, we interpret `swap out' as `deactivate pages', and we add
  generic ttm operations to wire and unwire pages, for the ttm_tt
  driver to use.
  This fixes certain graphics buffer eviction logic, which enables
  nouveau to suspend/resume on one of my machines.  (The machine
  doesn't resume overall for other reasons, but the nouveau device
  suspends and resumes in isolation.)
- Use bus_space_subregion to get fifo channels out of mmio registers.
  Evidently it is not enough to just map them separately.  Ran out of
  time to investigate why, last time I poked at this and confirmed this
  change works.
- Avoid taking locks during interrupts and explain why we are doing it this way.
- We now use cpu_intr_p() all the time.
