+Subject: ALSA: hda: Initialize power_state field properly
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 183ab39eb0ea9879bb68422a83e65f750f3192f0 upstream.
+
+The recent commit 98081ca62cba ("ALSA: hda - Record the current power
+state before suspend/resume calls") made the HD-audio driver to store
+the PM state in power_state field. This forgot, however, the
+initialization at power up. Although the codec drivers usually don't
+need to refer to this field in the normal operation, let's initialize
+it properly for consistency.

+
+From: Maxime Ripard <maxime@cerno.tech>
+
+commit 4c7eeb9af3e41ae7d840977119c58f3bbb3f4f59 upstream.
+
+The commit 7aa9b9eb7d6a ("arm64: dts: allwinner: H6: Add PMU mode")
+introduced support for the PMU found on the Allwinner H6. However, the
+binding only allows for a single compatible, while the patch was adding
+two.
+
+Make sure we follow the binding.

+Subject: mm: Use fixed constant in page_frag_alloc instead of size + 1
+
+From: Alexander Duyck <alexander.h.duyck@linux.intel.com>
+
+commit 8644772637deb121f7ac2df690cbf83fa63d3b70 upstream.
+
+This patch replaces the size + 1 value introduced with the recent fix for 1
+byte allocs with a constant value.
+
+The idea here is to reduce code overhead as the previous logic would have
+to read size into a register, then increment it, and write it back to
+whatever field was being used. By using a constant we can avoid those
+memory reads and arithmetic operations in favor of just encoding the
+maximum value into the operation itself.

+This fix addresses https://bugzilla.kernel.org/show_bug.cgi?id=201071

+Commit 5025f7f7d506 wrongly relied on __dev_change_flags to notify users of

+Fix it by indicating flag changes explicitly to __dev_notify_flags.
