20e76f1a70 dma-buf: Use struct dma_buf_map in dma_buf_vunmap() interfaces 
This patch updates dma_buf_vunmap() and dma-buf's vunmap callback to

This address is now given in an instance of the structure.

Users of the functions are updated accordingly. This is only an interface
change. It is currently expected that dma-buf memory can be accessed with
system memory load/store operations.

d693def4fd drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver 
Several GEM and PRIME callbacks have been deprecated in favor of
per-instance GEM object functions. Remove the callbacks as they are
now unused. The only exception is .gem_prime_mmap, which is still
in use by several drivers.

What is also gone is gem_vm_ops in struct drm_driver. All drivers now
use struct drm_gem_object_funcs.vm_ops instead.

While at it, the patch also improves error handling around calls
to .free and .get_sg_table callbacks.

v3:
	* restore default call to drm_gem_prime_export() in
	  drm_gem_prime_handle_to_fd()
	* return -ENOSYS if get_sg_table is not set
	* drop all checks for obj->funcs
	* clean up TODO list and documentation
v2:
	* update related TODO item (Sam)

9e9f605fb5 drm/doc: Document that modifiers are always required for fb 
Even for legacy userspace, since otherwise GETFB2 is broken and if you
switch between modifier-less and modifier-aware compositors, smooth
transitions break.

Also it's just best practice to make sure modifiers are invariant for
a given drm_fb, and that a modifier-aware kms drivers only has one
place to store them, ignoring any old implicit bo flags or whatever
else might float around.

Motivated by some irc discussion with Bas about amdgpu modifier
support.

db9c1734ad drm/ttm: stop dangerous caching attribute change 
When we swapout/in a BO we try to change the caching
attributes of the pages before/after doing the copy.

On x86 this is done by calling set_pages_uc(),
set_memory_wc() or set_pages_wb() for not highmem pages
to update the linear mapping of the page.

On all other platforms we do exactly nothing.

Now on x86 this is unnecessary because copy_highpage() will
either create a temporary mapping of the page which is wb
anyway and destroyed immediately again or use the linear
mapping with the correct caching attributes.

So stop this nonsense and just keep the caching as it is and
return an error when a driver tries to change the caching of
an already populated TT object.

This is much more defensive since changing caching
attributes is platform and driver specific and usually
doesn't work after the page was initially allocated.

Deal with more cases in drm_dp_downstream_max_bpc():
- DPCD 1.0 -> assume 8bpc for non-DP
- DPCD 1.1+ DP (or DP++ with DP sink) -> allow anything
- DPCD 1.1+ TMDS -> check the caps, assume 8bpc if the value is crap
- anything else -> assume 8bpc

Move bound up into the bo object, and keep populated with the tt
object.

The ghost object handling needs to follow the flags at the bo
level now instead of it being part of the ttm tt object.
