+Subject: ACPI: button: Add DMI quirk for Samsung Galaxy Book2 to fix initial lid detection issue
+
+From: Shubham Panwar <shubiisp8@gmail.com>
+
+commit 8fa73ee44daefc884c53a25158c25a4107eb5a94 upstream.
+
+Add a DMI quirk for Samsung Galaxy Book2 to fix an initial lid state
+detection issue.
+
+The _LID device incorrectly returns the lid status as "closed" during
+boot, causing the system to enter a suspend loop right after booting.
+
+The quirk ensures that the correct lid state is reported initially,
+preventing the system from immediately suspending after startup. It
+only addresses the initial lid state detection and ensures proper
+system behavior upon boot.

+commit bf58f03931fdcf7b3c45cb76ac13244477a60f44 upstream.
+
+If a BIOS provides bad data in response to an ATIF method call
+this causes a NULL pointer dereference in the caller.

+Subject: hv_netvsc: Fix VF namespace also in synthetic NIC NETDEV_REGISTER event
+
+From: Haiyang Zhang <haiyangz@microsoft.com>
+
+commit 4c262801ea60c518b5bebc22a09f5b78b3147da2 upstream.
+
+The existing code moves VF to the same namespace as the synthetic NIC
+during netvsc_register_vf(). But, if the synthetic device is moved to a
+new namespace after the VF registration, the VF won't be moved together.
+
+To make the behavior more consistent, add a namespace check for synthetic
+NIC's NETDEV_REGISTER event (generated during its move), and move the VF
+if it is not in the same namespace.

+Subject: nilfs2: fix kernel bug due to missing clearing of buffer delay flag
+
+From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
+
+commit 6ed469df0bfbef3e4b44fca954a781919db9f7ab upstream.
+
+Syzbot reported that after nilfs2 reads a corrupted file system image
+and degrades to read-only, the BUG_ON check for the buffer delay flag
+in submit_bh_wbc() may fail, causing a kernel bug.
+
+This is because the buffer delay flag is not cleared when clearing the
+buffer state flags to discard a page/folio or a buffer head. So, fix
+this.
+
+This became necessary when the use of nilfs2's own page clear routine
+was expanded. This state inconsistency does not occur if the buffer
+is written normally by log writing.
