Jason Gunthorpe 7da0d7a575 drm/amdgpu: Call find_vma under mmap_sem ... [ Upstream commit a9ae8731e6 ] find_vma() must be called under the mmap_sem, reorganize this code to do the vma check after entering the lock. Further, fix the unlocked use of struct task_struct's mm, instead use the mm from hmm_mirror which has an active mm_grab. Also the mm_grab must be converted to a mm_get before acquiring mmap_sem or calling find_vma().
