+Subject: ALSA: hda - Add a fixup for HP Folio 13 mute LED
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 37c367ecdb9a01c9acc980e6e17913570a1788a7 upstream.
+
+HP Folio 13 may have a broken BIOS that doesn't set up the mute LED
+GPIO properly, and the driver guesses it wrongly, too. Add a new
+fixup entry for setting the GPIO pin statically for this laptop.

+Subject: iio:gyro: bug on L3GD20H gyroscope support
+
+From: Denis CIOCCA <denis.ciocca@st.com>
+
+commit a0657716416f834ef7710a9044614d50a36c3bdc upstream.
+
+The driver was not able to manage the sensor: during probe function
+and wai check, the driver stops and writes: "device name and WhoAmI mismatch."
+The correct value of L3GD20H wai is 0xd7 instead of 0xd4.
+Dropped support for the sensor.

+Subject: perf: Fix hotplug splat
+
+From: Peter Zijlstra <peterz@infradead.org>
+
+commit e3703f8cdfcf39c25c4338c3ad8e68891cca3731 upstream.
+
+Drew Richardson reported that he could make the kernel go *boom* when hotplugging
+while having perf events active.
+
+It turned out that when you have a group event, the code in
+__perf_event_exit_context() fails to remove the group siblings from
+the context.
+
+We then proceed with destroying and freeing the event, and when you
+re-plug the CPU and try and add another event to that CPU, things go
+*boom* because you've still got dead entries there.

+
+The change (008fa749e0fe5b2fffd20b7fe4891bb80d072c6a) that moved the
+node release code to a separate function broke death notifications in
+some cases. When it encountered a reference without a death
+notification request, it would skip looking at the remaining
+references, and therefore fail to send death notifications for them.

+Subject: xtensa: introduce spill_registers_kernel macro
+
+From: Max Filippov <jcmvbkbc@gmail.com>
+
+commit e2fd1374c705abe4661df3fb6fadb3879c7c1846 upstream.
+
+Most in-kernel users want registers spilled on the kernel stack and
+don't require PS.EXCM to be set. That means that they don't need fixup
+routine and could reuse regular window overflow mechanism for that,
+which makes spill routine very simple.
