For typesafety, use container_of() instead of implicit cast from struct
ttm_tt to struct amdgpu_ttm_tt.

<title>drm/amdgpu: Adjust logic around GTT size (v3)</title>

<id>urn:sha1:f7ba887f606b1895dabf718547cf7397924f0d3a</id>
<content type='text'>
Certain GL unit tests for large textures can cause problems
with the OOM killer since there is no way to link this memory
to a process.  This was originally mitigated (but not necessarily
eliminated) by limiting the GTT size.  The problem is this limit
is often too low for many modern games so just make the limit 1/2
of system memory. The OOM accounting needs to be addressed, but
we shouldn't prevent common 3D applications from being usable
just to potentially mitigate that corner case.

Set default GTT size to max(3G, 1/2 of system ram) by default.

v2: drop previous logic and default to 3/4 of ram
v3: default to half of ram to align with ttm
v4: fix spelling in comment (Kent)

<content type='text'>
Add a AMDGPU_GEM_CREATE_DISCARDABLE flag to note that the content of a BO
doesn't needs to be preserved during eviction.

KFD was already using a similar functionality for SVM BOs so replace the
internal flag with the new UAPI.

<title>drm/amdgpu: Use TTM builtin resource manager debugfs code</title>

<content type='text'>
Switch to using the TTM resource manager debugfs helpers. It's
exactly the same functionality but the debugfs code is shared with
other drivers.

The TTM resource managers need to stay valid for as long as the
drm debugfs_root is valid.

<id>urn:sha1:7bc80a5462c37eab58a9ea386064307c0f447fd1</id>
<content type='text'>
This change adds the dma_resv_usage enum and allows us to specify why a
dma_resv object is queried for its containing fences.

Additional to that a dma_resv_usage_rw() helper function is added to aid
retrieving the fences for a read or write userspace submission.

This is then deployed to the different query functions of the dma_resv
object and all of their users. When the write paratermer was previously
true we now use DMA_RESV_USAGE_WRITE and DMA_RESV_USAGE_READ otherwise.

v2: add KERNEL/OTHER in separate patch
v3: some kerneldoc suggestions by Daniel
v4: some more kerneldoc suggestions by Daniel, fix missing cases lost in
    the rebase pointed out by Bas.

Instead of providing the bulk move structure for each LRU update set
this as property of the BO. This should avoid costly bulk move rebuilds
with some games under RADV.

v2: some name polishing, add a few more kerneldoc words.
v3: add some lockdep
v4: fix bugs, handle pin/unpin as well
v5: improve kerneldoc
