+Subject: ALSA: hda - apply STAC_9200_DELL_M22 quirk for Dell Latitude D430
+
+From: Alexander Tsoy <alexander@tsoy.me>
+
+commit 1fc2e41f7af4572b07190f9dec28396b418e9a36 upstream.
+
+This model is actually called 92XXM2-8 in Windows driver. But since pin
+configs for M22 and M28 are identical, just reuse M22 quirk.
+
+Fixes external microphone (tested) and probably docking station ports
+(not tested).

+Subject: drm/gma500/psb: Actually use VBT mode when it is found
+
+From: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
+
+commit 82bc9a42cf854fdf63155759c0aa790bd1f361b0 upstream.
+
+With LVDS we were incorrectly picking the pre-programmed mode instead of
+the prefered mode provided by VBT. Make sure we pick the VBT mode if
+one is provided. It is likely that the mode read-out code is still wrong
+but this patch fixes the immediate problem on most machines.

+
+From: Nicolas Iooss <nicolas.iooss_linux@m4x.org>
+
+commit ff5a20169b98d84ad8d7f99f27c5ebbb008204d6 upstream.
+
+Commit 5b5e0928f742 ("lib/vsprintf.c: remove %Z support") removed some
+usages of format %Z but forgot "%.2Zx". This makes clang 4.0 reports a
+-Wformat-extra-args warning because it does not know about %Z.
+
+Replace %Z with %z.

+Subject: slub/memcg: cure the brainless abuse of sysfs attributes
+
+From: Thomas Gleixner <tglx@linutronix.de>
+
+commit 478fe3037b2278d276d4cd9cd0ab06c4cb2e9b32 upstream.
+
+memcg_propagate_slab_attrs() abuses the sysfs attribute file functions
+to propagate settings from the root kmem_cache to a newly created
+kmem_cache. It does that with:
+
+ attr->show(root, buf);
+ attr->store(new, buf, strlen(bug);
+
+Aside of being a lazy and absurd hackery this is broken because it does
+not check the return value of the show() function.
+
+Some of the show() functions return 0 w/o touching the buffer. That
+means in such a case the store function is called with the stale content
+of the previous show(). That causes nonsense like invoking
+kmem_cache_shrink() on a newly created kmem_cache. In the worst case it
+would cause handing in an uninitialized buffer.
+
+This should be rewritten proper by adding a propagate() callback to
+those slub_attributes which must be propagated and avoid that insane
+conversion to and from ASCII, but that's too large for a hot fix.
+
+Check at least the return value of the show() function, so calling
+store() with stale content is prevented.
+
+Steven said:
+ "It can cause a deadlock with get_online_cpus() that has been uncovered
+ by recent cpu hotplug and lockdep changes that Thomas and Peter have
+ been doing.
+
+ Possible unsafe locking scenario:
+
+ CPU0 CPU1

+ lock(cpu_hotplug.lock);
+ lock(slab_mutex);
+ lock(cpu_hotplug.lock);
