+Subject: [PATCH] fix: mlock ignore [vectors] gate_vma
+
+Upstream-Status: Pending
+
+linux kernel has a new commit f9d4861f for [vectors] vma on ARM
+"ARM: 7294/1: vectors: use gate_vma for vectors user mapping".
+
+mlock()/munlock() on a gate_vma would cause NOMEM error, so add
+[vectors] to _ignore_maps[], as other gate_vmas [vdso]/[vsyscall]
+did.
