Bug Description

SRU Justification

       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The following upstream
       stable patches should be included in the Ubuntu kernel:

       v5.15.120 upstream stable release
       from git://git.kernel.org/

mptcp: fix possible divide by zero in recvmsg()
mptcp: consolidate fallback and non fallback state machine
mm, hwpoison: try to recover from copy-on write faults
mm, hwpoison: when copy-on-write hits poison, take page offline
drm/amdgpu: Set vmbo destroy after pt bo is created
x86/microcode/AMD: Load late on both threads too
x86/smp: Use dedicated cache-line for mwait_play_dead()
can: isotp: isotp_sendmsg(): fix return error fix on TX path
bpf: ensure main program has an extable
HID: wacom: Use ktime_t rather than int when dealing with timestamps
HID: logitech-hidpp: add HIDPP_QUIRK_DELAYED_INIT for the T651.
Revert "thermal/drivers/mediatek: Use devm_of_iomap to avoid resource leak in mtk_thermal_probe"
perf symbols: Symbol lookup with kcore can fail if multiple segments match stext
scripts/tags.sh: Resolve gtags empty index generation
drm/amdgpu: Validate VM ioctl flags.
parisc: Delete redundant register definitions in <asm/assembly.h>
nubus: Partially revert proc_create_single_data() conversion
