drm/nv50-nvc0: delay GART binding until move_notify time
The immediate benefit of doing this is that on NV50 and up, the GPU
virtual address of any buffer is now constant, regardless of what
memtype they're placed in.

drm/nvc0: allow creation of buffers with any non-compressed memtype

to allow any non-compressed type. Support for Z compression will come at
a later point.

drm/nv50-nvc0: restrict memtype to those specified at creation time
Upcoming patches are going to enable full support for buffers that keep
a constant GPU virtual address whenever they're validated for use by
the GPU.
In order for this to work properly while keeping support for large pages,
we need to know if it's ever going to be possible for a buffer to end
up in GART, and if so, disable large pages for the buffer's VMA.
This is a new restriction that's not present in earlier kernel's, but
should not break userspace as the current code never attempts to validate
buffers into a memtype other than it was created with.

drm/nv50-nvc0: activate/update ds channel's framebuffer on modesets
The hw doesn't really appear to be designed to be used the way we have to
use it due to DRI2's design. This leads us to having to keep the flipped
fb support active at all times.

drm/nv50-nvc0: request and wait on notification of modeset completion
This should prevent a number of races from occuring, the most obvious of
which will be exposed when we start making use of the "display sync" evo
channel for page flipping. The DS channel will reject any command stream
that doesn't completely agree with the current "master" state.

drm/nv50-nvc0: switch to tasklet for display isr bh
We need to be able to have the bh run while possibly spinning waiting for
the EVO notifier to signal. This apparently happens in some circumstances
with preempt disabled, so our workqueue was never being run.

drm/nouveau: make vbios parser runnable from an atomic context
The nv50 display isr bh needs to be converted to a tasklet, which means
we can't sleep anymore. The places we execute vbios init tables are
rare, and not in any way performance critical, so this isn't a huge
problem.

With cmwq, there's no reason for nouveau to use a dedicated workqueue.
Drop dev_priv->wq and use system_wq instead. Each work item is sync
flushed when the containing structure is unregistered/destroyed.
Note that this change also makes sure that nv50_gpio_handler is not
freed while the contained work item is still running.

drm: Trim the GEM mmap offset hashtab
Using an order 19 drm_ht for the mmap offsets is a little obscene. That
means that will a fully populated GTT with every single object mmaped at
least once in its lifetime, there will be exactly one object in each
bucket.
Typically systems only have at most a few thousand objects, though you
may see a KDE desktop hit 50000. And most of those should never be
mapped... On my systems, just using an order 10 ht would still have an
average occupancy less than 1, so apply a small safety factor and
use an order 12 ht, like the other mmap offset ht.

drm/ttm: call driver move_notify() when doing system->tt bo moves
Nouveau doesn't have enough information at ttm_backend_func.bind() time
to implement things like tiled GART, or to keep a buffer at a constant
address in the GPU virtual address space no matter where in physical
memory it's placed.
To resolve this, nouveau will handle binding of all buffers to the GPU
itself from the move_notify() hook. This commit ensures it's called
for all buffer moves.
Talked to Dave about the impact on radeon, which uses move_notify, it
doesn't look like anything should break there.

With struct drm_mm_node embedded, we cannot track allocations

drm: mm: track free areas implicitly
The idea is to track free holes implicitly by marking the allocation
immediatly preceeding a hole.
To avoid an ugly corner case add a dummy head_node to struct drm_mm
to track the hole that spans to complete allocation area when the
memory manager is empty.
To guarantee that there's always a preceeding/following node (that might
be marked as hole_follows == 1), move the mm->node_list list_head to the
head_node.
The main allocator and fair-lru scan code actually becomes simpler.
Only the debug code slightly suffers because free areas are no longer
explicit.
Also add drm_mm_for_each_node (which will be much more useful when
struct drm_mm_node is embeddable).

drm/nv40: fix tiling-related setup for a number of chipsets
Due to the default case handling the older chipsets, a bunch of the newer

This also makes nv4e touch the "extra" tiling regs. "nv" doesn't touch
