+Subject: drm/panel: simple: Fix Innolux G070Y2-L01 BPP settings
+
+From: Marek Vasut <marex@denx.de>
+
+[ Upstream commit fc1b6ef7bfb3d1d4df868b1c3e0480cacda6cd81 ]
+
+The Innolux G070Y2-L01 supports two modes of operation:
+1) FRC=Low/NC ... MEDIA_BUS_FMT_RGB666_1X7X3_SPWG ... BPP=6
+2) FRC=High ..... MEDIA_BUS_FMT_RGB888_1X7X4_SPWG ... BPP=8
+
+Currently the panel description mixes both, BPP from 1) and bus
+format from 2), which triggers a warning at panel-simple.c:615.
+
+Pick the later, set bpp=8, fix the warning.

+Subject: efi: fix return value of __setup handlers
+
+From: Randy Dunlap <rdunlap@infradead.org>
+
+[ Upstream commit 9feaf8b387ee0ece9c1d7add308776b502a35d0c ]
+
+When "dump_apple_properties" is used on the kernel boot command line,
+it causes an Unknown parameter message and the string is added to init's
+argument strings:
+
+ Unknown kernel command line parameters "dump_apple_properties
+ BOOT_IMAGE=/boot/bzImage-517rc6 efivar_ssdt=newcpu_ssdt", will be
+ passed to user space.
+
+ Run /sbin/init as init process
+ with arguments:
+ /sbin/init
+ dump_apple_properties
+ with environment:
+ HOME=/
+ TERM=linux
+ BOOT_IMAGE=/boot/bzImage-517rc6
+ efivar_ssdt=newcpu_ssdt
+
+Similarly when "efivar_ssdt=somestring" is used, it is added to the
+Unknown parameter message and to init's environment strings, polluting
+them (see examples above).
+
+Change the return value of the __setup functions to 1 to indicate
+that the __setup options have been handled.

+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit c700525fcc06b05adfea78039de02628af79e07a ]
+
+syzbot found that when an AF_PACKET socket is using PACKET_COPY_THRESH
+and mmap operations, tpacket_rcv() is queueing skbs with
+garbage in skb->cb[], triggering a too big copy [1]
+
+Presumably, users of af_packet using mmap() already gets correct
+metadata from the mapped buffer, we can simply make sure
+to clear 12 bytes that might be copied to user space later.
