+Subject: ACPI: sysfs: Prefer "compatible" modalias
+
+From: Kai-Heng Feng <kai.heng.feng@canonical.com>
+
+commit 36af2d5c4433fb40ee2af912c4ac0a30991aecfc upstream.
+
+Commit 8765c5ba1949 ("ACPI / scan: Rework modalias creation when
+"compatible" is present") may create two "MODALIAS=" in one uevent
+file if specific conditions are met.
+
+This breaks systemd-udevd, which assumes each "key" in one uevent file
+to be unique. The internal implementation of systemd-udevd overwrites
+the first MODALIAS with the second one, so its kmod rule doesn't load
+the driver for the first MODALIAS.
+
+So if both the ACPI modalias and the OF modalias are present, use the
+latter to ensure that there will be only one MODALIAS.

+Subject: ALSA: hda/via: Apply the workaround generically for Clevo machines
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 4961167bf7482944ca09a6f71263b9e47f949851 upstream.
+
+We've got another report indicating a similar problem wrt the
+power-saving behavior with VIA codec on Clevo machines. Let's apply
+the existing workaround generically to all Clevo devices with VIA
+codecs to cover all in once.

+Subject: kernel: kexec: remove the lock operation of system_transition_mutex
+
+From: Baoquan He <bhe@redhat.com>
+
+commit 56c91a18432b631ca18438841fd1831ef756cabf upstream.
+
+Function kernel_kexec() is called with lock system_transition_mutex
+held in reboot system call. While inside kernel_kexec(), it will
+acquire system_transition_mutex agin. This will lead to dead lock.
+
+The dead lock should be easily triggered, it hasn't caused any
+failure report just because the feature 'kexec jump' is almost not
+used by anyone as far as I know. An inquiry can be made about who
+is using 'kexec jump' and where it's used. Before that, let's simply
+remove the lock operation inside CONFIG_KEXEC_JUMP ifdeffery scope.
