The patch titled
uselib: add missing MNT_NOEXEC check
has been removed from the -mm tree. Its filename was
uselib-add-missing-mnt_noexec-check.patch

------------------------------------------------------
Subject: uselib: add missing MNT_NOEXEC check
From: Christoph Hellwig <hch@xxxxxx>
We don't allow loading ELF shared library from noexec points so the
same should apply to sys_uselib aswell.
