This reverts commit 5cc6f623f4 which is
commit 1b6a6fc5280e97559287b61eade2d4b363e836f2 upstream.
It breaks the Android kernel ABI and is not needed for Android devices,
so it is safe to revert for now. If it is determined that it is needed
in the future, it can be brought back in an abi-preserving way.
