In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix amdgpu_hmm_range_get_pages The notifier sequence must only be read once or otherwise we could work with invalid pages. While at it also fix the coding style, e.g. drop the pre-initialized return value and use the common define for 2G range. (cherry picked from commit c08972f555945cda57b0adb72272a37910153390)
