+Subject: s390: Add pgste to ptep_modify_prot_start()
+To: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+Cc: stable@vger.kernel.org, linux-s390@vger.kernel.org, Debian kernel maintainers <debian-kernel@lists.debian.org>

+Commit 52f36be0f4e2 's390/pgtable: Fix check for pgste/storage key
+handling', which was commit b56433cb782d upstream, added a use of
+pgste to ptep_modify_prot_start(), but this variable does not exist.
+In mainline, pgste was added by commit d3383632d4e8 's390/mm: add pte
+invalidation notifier for kvm' and initialised to the return value of
+pgste_get_lock(ptep).  Initialise it similarly here.
+
+Compile-tested only.
