+Subject: [PATCH 06/13] ACPI: PM: s2idle: Rework ACPI events synchronization
+
+Note that the EC GPE processing need not be synchronized in
+acpi_s2idle_wake() after invoking acpi_ec_dispatch_gpe(), because
+that function checks the GPE status and dispatches its handler if
+need be and the SCI action handler is not going to run anyway at
+that point.
+
+Moreover, it is better to drain all of the pending ACPI events
+before restoring the working-state configuration of GPEs in
+acpi_s2idle_restore(), because those events are likely to be related
+to system wakeup, in which case they will not be relevant going
+forward.
+
+Rework the code to take these observations into account.

+Commit 809805a820c6 refactored the cfg mangling. Unfortunately, in this
+process the lines which picked the right cfg for Killer Qu C0 NICs after
+C0 detection were lost. These lines were added by commit b9500577d361.
+
+I suspect this is more of the "merge damage" which commit 7cded5658329

+Subject: [PATCH 10/13] drm/i915: Fix audio power up sequence for gen10+
+ display
+
+On platfroms with gen10+ display, driver must set the enable bit of
+AUDIO_PIN_BUF_CTL register before transactions with the HDA controller
+can proceed. Add setting this bit to the audio power up sequence.
+
+Failing to do this resulted in errors during display audio codec probe,
+and failures during resume from suspend.
+
+Note: We may also need to disable the bit afterwards, but there are
+still unresolved issues with that.

+Subject: [PATCH 12/13] drm/i915/gt: Detect if we miss WaIdleLiteRestore
+
+In order to avoid confusing the HW, we must never submit an empty ring
+during lite-restore, that is we should always advance the RING_TAIL
+before submitting to stay ahead of the RING_HEAD.
+
+Normally this is prevented by keeping a couple of spare NOPs in the
+request->wa_tail so that on resubmission we can advance the tail. This
+relies on the request only being resubmitted once, which is the normal
+condition as it is seen once for ELSP[1] and then later in ELSP[0]. On
+preemption, the requests are unwound and the tail reset back to the
+normal end point (as we know the request is incomplete and therefore its
+RING_HEAD is even earlier).
+
+However, if this w/a should fail we would try and resubmit the request
+with the RING_TAIL already set to the location of this request's wa_tail
+potentially causing a GPU hang. We can spot when we do try and
+incorrectly resubmit without advancing the RING_TAIL and spare any
+embarrassment by forcing the context restore.
+
+In the case of preempt-to-busy, we leave the requests running on the HW
+while we unwind. As the ring is still live, we cannot rewind our
+rq->tail without forcing a reload so leave it set to rq->wa_tail and
+only force a reload if we resubmit after a lite-restore. (Normally, the
+forced reload will be a part of the preemption event.)
