+Subject: cgroup/cpuset: Fix "suspicious RCU usage" lockdep warning
+
+From: Waiman Long <longman@redhat.com>
+
+commit 2bdfd2825c9662463371e6691b1a794e97fa36b4 upstream.
+
+It was found that a "suspicious RCU usage" lockdep warning was issued
+with the rcu_read_lock() call in update_sibling_cpumasks(). It is
+because the update_cpumasks_hier() function may sleep. So we have
+to release the RCU lock, call update_cpumasks_hier() and reacquire
+it afterward.
+
+Also add a percpu_rwsem_assert_held() in update_sibling_cpumasks()
+instead of stating that in the comment.
+
+Fixes: 4716909cc5c5 ("cpuset: Track cpusets that use parent's effective_cpus")

+commit 4223f86512877b04c932e7203648b37eec931731 upstream.
+
+Make MediaTek MT753x DSA driver enable MediaTek Gigabit PHYs driver to
+properly control MT7530 and MT7531 switch PHYs.
+
+A noticeable change is that the behaviour of switchport interfaces going
+up-down-up-down is no longer there.

+Subject: tools include UAPI: Sync sound/asound.h copy with the kernel sources
+
+From: Arnaldo Carvalho de Melo <acme@redhat.com>
+
+commit 4f2492731ada9d702ffdfaa6ec1ff64820a1664c upstream.
+
+Picking the changes from:
+
+ 06feec6005c9d950 ("ASoC: hdmi-codec: Fix OOB memory accesses")
+
+Which entails no changes in the tooling side as it doesn't introduce new
+SNDRV_PCM_IOCTL_ ioctls.
+
+To silence this perf tools build warning:
+
+ Warning: Kernel ABI header at 'tools/include/uapi/sound/asound.h' differs from latest version at 'include/uapi/sound/asound.h'
+ diff -u tools/include/uapi/sound/asound.h include/uapi/sound/asound.h
