+Subject: drm/amd/display: Add monitor specific edid quirk
+
+From: Aurabindo Pillai <aurabindo.pillai@amd.com>
+
+commit 613a7956deb3b1ffa2810c6d4c90ee9c3d743dbb upstream.
+
+Disable FAMS on a Samsung Odyssey G9 monitor. Experiments show that this
+monitor does not work well under some use cases, and is likely
+implementation specific bug on the monitor's firmware.

+Subject: drm/amdgpu: fix clearing mappings for BOs that are always valid in VM
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Samuel Pitoiset <samuel.pitoiset@gmail.com>
+
+commit ea2c3c08554601b051d91403a241266e1cf490a5 upstream.
+
+Per VM BOs must be marked as moved or otherwise their ranges are not
+updated on use which might be necessary when the replace operation
+splits mappings.
+
+This fixes random GPU hangs when replacing sparse mappings from the
+userspace, while OP_MAP/OP_UNMAP works fine because always valid BOs
+are correctly handled there.

+Subject: serial: atmel: don't enable IRQs prematurely
+
+From: Dan Carpenter <dan.carpenter@linaro.org>
+
+commit 27a826837ec9a3e94cc44bd9328b8289b0fcecd7 upstream.
+
+The atmel_complete_tx_dma() function disables IRQs at the start
+of the function by calling spin_lock_irqsave(&port->lock, flags);
+There is no need to disable them a second time using the
+spin_lock_irq() function and, in fact, doing so is a bug because
+it will enable IRQs prematurely when we call spin_unlock_irq().
+
+Just use spin_lock/unlock() instead without disabling or enabling
+IRQs.
