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.
