Add the msm_disp_snapshot module which adds supports to dump dpu
registers and capture the drm atomic state which can be used in
case of error conditions.
changes in v5:
- start storing disp_state in msm_kms instead of dpu_kms
- get rid of MSM_DISP_SNAPSHOT_IN_* enum by simplifying the functions
- move snprintf inside the snapshot core by using varargs
- get rid of some stale code comments
- allow snapshot module for non-DPU targets

irq_hpd interrupt should be handled after dongle plugged in and
before dongle unplugged. Hence irq_hpd interrupt is enabled at
the end of the plugin handle and disabled at the beginning of
unplugged handle. Current irq_hpd with sink_count = 0 is wrongly
handled same as the dongle unplugged which tears down the mainlink
and disables the phy. This patch fixes this problem by only tearing
down the mainlink but keeping phy enabled at irq_hpd with
sink_count = 0 handle so that next irq_hpd with sink_count =1 can be
handled by setup mainlink only. This patch also set dongle into D3
(power off) state at end of handling irq_hpd with sink_count = 0.
Changes in v2:
-- add ctrl->phy_Power_count
Changes in v3:
-- del ctrl->phy_Power_count
-- add phy_power_off to dp_ctrl_off_link_stream()
Changes in v4:
-- return immediately if clock disable failed at dp_ctrl_off_link_stream()

After panel power up, if PSR entry attempted too early,
PSR state may get stuck in transition.
This could happen if the panel is not ready

since abortion is not permitted after the SDP has been sent.

ASan reported a memory leak of BPF-related ksymbols map and dso. The
leak is caused by refount never reaching 0, due to missing __put calls
in the function machine__process_ksymbol_register.
Once the dso is inserted in the map, dso__put() should be called
(map__new2() increases the refcount to 2).
The same thing applies for the map when it's inserted into maps
(maps__insert() increases the refcount to 2).

The following command segfaults on my x86 broadwell:
$ ./perf stat -M frontend_bound,retiring,backend_bound,bad_speculation sleep 1
WARNING: grouped events cpus do not match, disabling group:
anon group { raw 0x10e }
anon group { raw 0x10e }
perf: util/evsel.c:1596: get_group_fd: Assertion `!(!leader->core.fd)' failed.
Aborted (core dumped)
The issue shows itself as a use-after-free in evlist__check_cpu_maps(),
whereby the leader of an event selector (evsel) has been deleted (yet we
still attempt to verify for an evsel).
Fundamentally the problem comes from metricgroup__setup_events() ->
find_evsel_group(), and has developed from the previous fix attempt in
commit 9c880c24cb ("perf metricgroup: Fix for metrics containing
duration_time").
The problem now is that the logic in checking if an evsel is in the same
group is subtly broken for the "cycles" event. For the "cycles" event,
the pmu_name is NULL; however the logic in find_evsel_group() may set an
event matched against "cycles" as used, when it should not be.
This leads to a condition where an evsel is set, yet its leader is not.
Fix the check for evsel pmu_name by not matching evsels when either has a
NULL pmu_name.
There is still a pre-existing metric issue whereby the ordering of the
metrics may break the 'stat' function, as discussed at:

After some investigation, I think I found the root cause: commit
2bfc6cd81b ("move kernel mapping outside of linear mapping") moves
BPF JIT region after the kernel:
| #define BPF_JIT_REGION_START PFN_ALIGN((unsigned long)&_end)
The &_end is unlikely aligned with PMD size, so the front bpf jit
region sits with part of kernel .data section in one PMD size mapping.
But kernel is mapped in PMD SIZE, when bpf_jit_binary_lock_ro() is
called to make the first bpf jit prog ROX, we will make part of kernel
.data section RO too, so when we write to, for example memset the
.data section, MMU will trigger a store page fault.
To fix the issue, we need to ensure the BPF JIT region is PMD size
aligned. This patch acchieve this goal by restoring the BPF JIT region
to original position, I.E the 128MB before kernel .text section. The
modification to kasan_init.c is inspired by Alexandre.

commit 2bfc6cd81b ("riscv: Move kernel mapping outside of linear

mapping. Currently, MODULES_VADDR is defined as below for RV64:
| #define MODULES_VADDR (PFN_ALIGN((unsigned long)&_end) - SZ_2G)
But kasan_init() has two local variables which are also named as _start,
_end, so MODULES_VADDR is evaluated with the local variable _end
rather than the global "_end" as we expected. Fix this issue by
renaming the two local variables.

- netfilter: nft_fib_ipv6: skip ipv6 packets from any to link-local
- udp: fix race between close() and udp_abort() resulting in a panic
- fix out of bounds when parsing TCP options before packets are
validated (in netfilter: synproxy, tc: sch_cake and mptcp)
- mptcp: improve operation under memory pressure, add missing
wake-ups
- mptcp: fix double-lock/soft lookup in subflow_error_report()
- bridge: fix races (null pointer deref and UAF) in vlan tunnel
egress
- ena: fix DMA mapping function issues in XDP
- rds: fix memory leak in rds_recvmsg
Misc:
- vrf: allow larger MTUs
- icmp: don't send out ICMP messages with a source address of 0.0.0.0
- cdc_ncm: switch to eth%d interface naming"

Pull btrfs fix from David Sterba:
"One more fix, for a space accounting bug in zoned mode. It happens
when a block group is switched back rw->ro and unusable bytes (due to
zoned constraints) are subtracted twice.
It has user visible effects so I consider it important enough for late
-rc inclusion and backport to stable"

btrfs: zoned: fix negative space_info->bytes_readonly
Once drm_framebuffer_init has returned 0, the framebuffer is hooked up
to the reference counting machinery and can no longer be destroyed with
a simple kfree. Therefore, it must be called last.
If drm_framebuffer_init returns 0 but its caller then returns non-0,
there will likely be memory corruption fireworks down the road.
The following lead me to this fix:
