+Subject: Revert "arm64: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO"
+Forwarded: not-needed
+
+This reverts commit a7408eca94745c441acb1c6b55ebeb08b735bf1f which
+was commit 3146bc64d12377a74dbda12b96ea32da3774ae07 upstream.
+The bug doesn't cause a real problem yet and the fix changes
+struct mm_struct which breaks the module ABI.
