<content type='text'>
Get the amdgpu_device from the DRM device by use
of an inline function, drm_to_adev(). The inline
function resolves a pointer to struct drm_device
to a pointer to struct amdgpu_device.

v2: Use a typed visible static inline function
    instead of an invisible macro.

<content type='text'>
The whole approach wasn't thought through till the end.

We already had a reset lock like this in the past and it caused the same problems like this one.

Completely revert the patch for now and add individual trylock protection to the hardware access functions as necessary.

This reverts commit df9c8d1aa278c435c30a69b8f2418b4a52fcb929.

Backmerging drm-next into drm-misc-next for nouveau and panel updates.
Resolves a conflict between ttm and nouveau, where struct ttm_mem_res got
renamed to struct ttm_resource.

This name makes a lot more sense, since these are about managing
driver resources rather than just memory ranges.

<id>urn:sha1:df9c8d1aa278c435c30a69b8f2418b4a52fcb929</id>
<content type='text'>
when GPU hang, driver has multi-paths to enter amdgpu_device_gpu_recover,
the atomic adev-&gt;in_gpu_reset and hive-&gt;in_reset are used to avoid
re-entering GPU recovery.

During GPU reset and resume, it is unsafe that other threads access GPU,
which maybe cause GPU reset failed. Therefore the new rw_semaphore
adev-&gt;reset_sem is introduced, which protect GPU from being accessed by
external threads during recovery.

v2:
1. add rwlock for some ioctls, debugfs and file-close function.
2. change to use dqm-&gt;is_resetting and dqm_lock for protection in kfd
driver.
3. remove try_lock and change adev-&gt;in_gpu_reset as atomic, to avoid
re-enter GPU recovery for the same GPU hang.

v3:
1. change back to use adev-&gt;reset_sem to protect kfd callback
functions, because dqm_lock couldn't protect all codes, for example:
free_mqd must be called outside of dqm_lock;

2. remove try_lock and introduce atomic hive-&gt;in_reset, to avoid

v4:
1. remove an unnecessary whitespace change in kfd_chardev.c
2. remove comment codes in amdgpu_device.c
3. add more detailed comment in commit message
4. define a wrap function amdgpu_in_reset

v5:
1. Fix some style issues.
