+Subject: media: mediatek: vcodec: adding lock to protect decoder context list
+
+From: Yunfei Dong <yunfei.dong@mediatek.com>
+
+[ Upstream commit 6467cda18c9f9b5f2f9a0aa1e2861c653e41f382 ]
+
+Add a lock for the ctx_list, to avoid accessing a NULL pointer
+within the 'vpu_dec_ipi_handler' function when the ctx_list has
+been deleted due to an unexpected behavior on the SCP IP block.

+Subject: media: mediatek: vcodec: Fix oops when HEVC init fails
+
+From: Nicolas Dufresne <nicolas.dufresne@collabora.com>
+
+[ Upstream commit 97c75ee5de060d271d80109b0c47cb6008439e5b ]
+
+The stateless HEVC decoder saves the instance pointer in the context
+regardless if the initialization worked or not. This caused a use after
+free, when the pointer is freed in case of a failure in the deinit
+function.
+Only store the instance pointer when the initialization was successful,
+to solve this issue.

+Subject: nouveau: fix devinit paths to only handle display on GSP.
+
+From: Dave Airlie <airlied@gmail.com>
+
+[ Upstream commit 718c4fb221dbeff9072810841b949413c5ffc345 ]
+
+This reverts:
+nouveau/gsp: don't check devinit disable on GSP.
+and applies a further fix.
+
+It turns out the open gpu driver, checks this register,
+but only for display.
+
+Match that behaviour and in the turing path only disable
+the display block. (ampere already only does displays).
+
+Fixes: 5d4e8ae6e57b ("nouveau/gsp: don't check devinit disable on GSP.")

+Subject: platform/x86/intel/hid: Don't wake on 5-button releases
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: David McFarland <corngood@gmail.com>
+
+[ Upstream commit 5864e479ca4344f3a5df8074524da24c960f440b ]
+
+If, for example, the power button is configured to suspend, holding it
+and releasing it after the machine has suspended, will wake the machine.
+
+Also on some machines, power button release events are sent during
+hibernation, even if the button wasn't used to hibernate the machine.
+This causes hibernation to be aborted.
+
+Fixes: 0c4cae1bc00d ("PM: hibernate: Avoid missing wakeup events during hibernation")

+Subject: platform/x86: intel-vbtn: Update tablet mode switch at end of probe
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Gwendal Grignou <gwendal@chromium.org>
+
+[ Upstream commit 434e5781d8cd2d0ed512d920c6cdeba4b33a2e81 ]
+
+ACER Vivobook Flip (TP401NAS) virtual intel switch is implemented as
+follow:
+
+ Device (VGBI)
+ {
+ Name (_HID, EisaId ("INT33D6") ...
+ Name (VBDS, Zero)
+ Method (_STA, 0, Serialized) // _STA: Status ...
+ Method (VBDL, 0, Serialized)
+ {
+ PB1E |= 0x20
+ VBDS |= 0x40
+ }
+ Method (VGBS, 0, Serialized)
+ {
+ Return (VBDS) /* \_SB_.PCI0.SBRG.EC0_.VGBI.VBDS */
+ }
+ ...
+ }
+
+By default VBDS is set to 0. At boot it is set to clamshell (bit 6 set)
+only after method VBDL is executed.
+
+Since VBDL is now evaluated in the probe routine later, after the device
+is registered, the retrieved value of VBDS was still 0 ("tablet mode")
+when setting up the virtual switch.
+
+Make sure to evaluate VGBS after VBDL, to ensure the
+convertible boots in clamshell mode, the expected default.
+

+Subject: randomize_kstack: Improve entropy diffusion
+
+From: Kees Cook <keescook@chromium.org>
+
+[ Upstream commit 9c573cd313433f6c1f7236fe64b9b743500c1628 ]
+
+The kstack_offset variable was really only ever using the low bits for
+kernel stack offset entropy. Add a ror32() to increase bit diffusion.
