Title
drm/amdgpu: fix AMDGPU_INFO_READ_MMR_REG
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix AMDGPU_INFO_READ_MMR_REG There were multiple issues in that code. First of all the order between the reset semaphore and the mm_lock was wrong (e.g. copy_to_user) was called while holding the lock. Then we allocated memory while holding the reset semaphore which is also a pretty big bug and can deadlock. Then we used down_read_trylock() instead of waiting for the reset to finish. (cherry picked from commit 361b6e6b303d4b691f6c5974d3eaab67ca6dd90e)

reset semaphore and the mm_lock was\\nwrong (e.g. copy_to_user) was called while holding the lock.\\n\\nThen we allocated memory while holding the reset semaphore which is also\\na pretty big bug and can deadlock.\\n\\nThen we used down_read_trylock() instead of waiting for the reset to\\nfinish.\\n\\n(cherry picked from commit
