However, the return value of regmap_read() was never checked. This is
fine, as long as the two arrays are zero-initialized, so that we don't
compare the vendor/product IDs against whatever garbage is left on the

Specifically document the new/clarified rules around how the shared
fences do not have any ordering requirements against the exclusive
fence.

But also document all the things a bit better, given how central
struct dma_resv to dynamic buffer management the docs have been very
inadequat.

- Lots more links to other pieces of the puzzle. Unfortunately
  ttm_buffer_object has no docs, so no links :-(

- Explain/complain a bit about dma_resv_locking_ctx(). I still don't
  like that one, but fixing the ttm call chains is going to be
  horrible. Plus we want to plug in real slowpath locking when we do
  that anyway.

- Main part of the patch is some actual docs for struct dma_resv.

Overall I think we still have a lot of bad naming in this area (e.g.
dma_resv.fence is singular, but contains the multiple shared fences),
but I think that's more indicative of how the semantics and rules are
just not great.

Another thing that's real awkard is how chaining exclusive fences
right now means direct dma_resv.exclusive_fence pointer access with an
rcu_assign_pointer. Not so great either.

v2:
- Fix a pile of typos (Matt, Jason)
- Hammer it in that breaking the rules leads to use-after-free issues

There's only one exclusive slot, and we must not break the ordering.

Adding a new exclusive fence drops all previous fences from the
dma_resv. To avoid violating the signalling order we err on the side of
over-synchronizing by waiting for the existing fences, even if
userspace asked us to ignore them.

A better fix would be to us a dma_fence_chain or _array like e.g.
amdgpu now uses, but
- msm has a synchronous dma_fence_wait for anything from another
  context, so doesn't seem to care much,
- and it probably makes sense to lift this into dma-resv.c code as a
  proper concept, so that drivers don't have to hack up their own
  solution each on their own.

Aside: The chaining of the various jobs is a bit awkward, with the
possibility of failure in bad places. I think with the
