drm/amdgpu: move get_user_pages out of amdgpu_ttm_tt_pin_userptr v6

2016-03-08T16:01:50Z

That avoids lock inversion between the BO reservation lock and the anon_vma lock. v2: * Changed amdgpu_bo_list_entry.user_pages to an array of pointers * Lock mmap_sem only for get_user_pages * Added invalidation of unbound userpointer BOs * Fixed memory leak and page reference leak v3 (chk): * Revert locking mmap_sem only for_get user_pages * Revert adding invalidation of unbound userpointer BOs * Sanitize and fix error handling v4 (chk): * Init userpages pointer everywhere. * Fix error handling when get_user_pages() fails. * Add invalidation of unbound userpointer BOs again. v5 (chk): * Add maximum number of tries. v6 (chk): * Fix error handling when we run out of tries.
