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

<id>urn:sha1:e07ddb0ce7cde64fdfcd96e96d1dce8538fa0bb0</id>
<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

<content type='text'>
While the current amdgpu doesn't support TMZ, it will return the error if user
mode would like to allocate secure buffer.

v2: we didn't need this checking anymore.
v3: only print message once time.

<id>urn:sha1:c6252390fccdd768d1250a45cbd2a7e3610a1283</id>
<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.
