+Subject: ACPI: sbshc: remove raw pointer from printk() message
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+commit 43cdd1b716b26f6af16da4e145b6578f98798bf6 upstream.
+
+There's no need to be printing a raw kernel pointer to the kernel log at
+every boot. So just remove it, and change the whole message to use the
+correct dev_info() call at the same time.

+Subject: ftrace: Remove incorrect setting of glob search field
+
+From: Steven Rostedt (VMware) <rostedt@goodmis.org>
+
+commit 7b6586562708d2b3a04fe49f217ddbadbbbb0546 upstream.
+
+__unregister_ftrace_function_probe() will incorrectly parse the glob filter
+because it resets the search variable that was setup by filter_parse_regex().
+
+Al Viro reported this:
+
+ After that call of filter_parse_regex() we could have func_g.search not
+ equal to glob only if glob started with '!' or '*'. In the former case
+ we would've buggered off with -EINVAL (not = 1). In the latter we
+ would've set func_g.search equal to glob + 1, calculated the length of
+ that thing in func_g.len and proceeded to reset func_g.search back to
+ glob.
+
+ Suppose the glob is e.g. *foo*. We end up with
+ func_g.type = MATCH_MIDDLE_ONLY;
+ func_g.len = 3;
+ func_g.search = "*foo";
+ Feeding that to ftrace_match_record() will not do anything sane - we
+ will be looking for names containing "*foo" (->len is ignored for that
+ one).

+Subject: mn10300/misalignment: Use SIGSEGV SEGV_MAPERR to report a failed user copy
+
+From: Eric W. Biederman <ebiederm@xmission.com>
+
+commit 6ac1dc736b323011a55ecd1fc5897c24c4f77cbd upstream.
+
+Setting si_code to 0 is the same a setting si_code to SI_USER which is definitely
+not correct. With si_code set to SI_USER si_pid and si_uid will be copied to
+userspace instead of si_addr. Which is very wrong.
+
+So fix this by using a sensible si_code (SEGV_MAPERR) for this failure.

+Subject: nvme: Fix managing degraded controllers
+To: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+Cc: Linux NVMe <linux-nvme@lists.infradead.org>, stable@vger.kernel.org
+Message-ID: <20180213161936.GE20962@localhost.localdomain>
+Content-Disposition: inline
+
+From: Keith Busch <keith.busch@intel.com>
+
+commit 5bae7f73d378a986 upstream
+
+Upstream is a near rewrite of the async nvme probe that ultimately didn't
+even cleanly merge in 4.5. This patch is a much smaller change targeted
+to the regression introduced in 4.4.
+
+If a controller is in a degraded mode that needs admin assistence to
+recover, we need to leave the controller running. We just want to disable
+namespace access without shuting the controller down.

+Subject: ovl: fix failure to fsync lower dir
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Amir Goldstein <amir73il@gmail.com>
+
+commit d796e77f1dd541fe34481af2eee6454688d13982 upstream.
+
+As a writable mount, it is not expected for overlayfs to return
+EINVAL/EROFS for fsync, even if dir/file is not changed.
+
+This commit fixes the case of fsync of directory, which is easier to
+address, because overlayfs already implements fsync file operation for
+directories.
+
+The problem reported by Raphael is that new PostgreSQL 10.0 with a
+database in overlayfs where lower layer in squashfs fails to start.
+The failure is due to fsync error, when PostgreSQL does fsync on all
+existing db directories on startup and a specific directory exists
+lower layer with no changes.
