<title>drm/amd: remove _unlocked suffix in drm_gem_object_put_unlocked</title>

<content type='text'>
Spelling out _unlocked for each and every driver is a annoying.
Especially if we consider how many drivers, do not know (or need to)
about the horror stories involving struct_mutex.

Just drop the suffix. It makes the API cleaner.

Done via the following script:

__from=drm_gem_object_put_unlocked
__to=drm_gem_object_put
for __file in $(git grep --name-only $__from); do
  sed -i  "s/$__from/$__to/g" $__file;
done

While the current amdgpu doesn't support TMZ, it will return the error if user

v2: we didn't need this checking anymore.

<content type='text'>
Implement an accessor of adev-&gt;tmz.enabled. Let not
code around access it as "if (adev-&gt;tmz.enabled)"
as the organization may change. Instead...

Recruit "bool amdgpu_is_tmz(adev)" to return
exactly this Boolean value. That is, this function
is now an accessor of an already initialized and
set adev and adev-&gt;tmz.

Add "void amdgpu_gmc_tmz_set(adev)" to check and
set adev-&gt;gmc.tmz_enabled at initialization
time. After which one uses "bool
amdgpu_is_tmz(adev)" to query whether adev
supports TMZ.

Also, remove circular header file include.

v2: Remove amdgpu_tmz.[ch] as requested.
v3: Move TMZ into GMC.

The alignment should match the page size for secure buffer, so we didn't
configure it anymore.

If a buffer object is secure, i.e. created with
AMDGPU_GEM_CREATE_ENCRYPTED, then the TMZ bit of
the PTEs that belong the buffer object should be
set.

v1: design and draft the skeletion of TMZ bits setting on PTEs (Alex)
v2: return failure once create secure BO on non-TMZ platform  (Ray)
v3: amdgpu_bo_encrypted() only checks the BO (Luben)
v4: move TMZ flag setting into amdgpu_vm_bo_update  (Christian)

The problem is that we can't add the clear fence to the BO
when there is an exclusive fence on it since we can't
guarantee the the clear fence will complete after the
exclusive one.

To fix this refactor the function and also add the exclusive
fence as shared to the resv object.

v2: fix warning
v3: add excl fence as shared instead
v4: squash in fix for fence handling in amdgpu_gem_object_close
