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.

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

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

for all buffer moves.

doesn't look like anything should break there.

To avoid an ugly corner case add a dummy head_node to struct drm_mm

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.

struct drm_mm_node is embeddable).

drm: dumb scanout create/mmap for intel/radeon (v3)
This is just an idea that might or might not be a good idea,
it basically adds two ioctls to create a dumb and map a dumb buffer
suitable for scanout. The handle can be passed to the KMS ioctls to create
a framebuffer.
It looks to me like it would be useful in the following cases:
a) in development drivers - we can always provide a shadowfb fallback.
b) libkms users - we can clean up libkms a lot and avoid linking
to libdrm_*.
c) plymouth via libkms is a lot easier.
Userspace bits would be just calls + mmaps. We could probably
mark these handles somehow as not being suitable for acceleartion
so as top stop people who are dumber than dumb.
