I overlooked the issue because when I was working on the said commit,
only the front audio is tested. Apology for that.
Changing supports_autosuspend in driver is too late for disabling
autosuspend, because it was already used by USB probe routine, so it can
break the balance on the following code that depends on
supports_autosuspend.
Fix it by using usb_disable_autosuspend() helper, and balance the
suspend count in disconnect callback.

In the case of MSO (Multi-SST Operation), the EDID contains the timings
for a single panel segment. We'll want to hide the fact from userspace,
and expose modes that span the entire display.
Don't modify the EDID, as the userspace should not use that for
modesetting, only modify the actual modes.
v3: Use pixel overlap if available.
v2: Rename intel_dp_mso_mode_fixup -> intel_edp_mso_mode_fixup

Add splitter configuration to crtc state, and read it where
supported. Also add splitter state dumping. The stream splitter will be
required for eDP MSO.
v4:
- Catch invalid splitter configuration (Uma)
v3:
- Convert segment timings to full panel timings.
- Refer to splitter instead of mso in crtc state.
- Dump splitter state.
v2: Add warning for mso being enabled on pipes other than A.

Currently if stream->signal is neither SIGNAL_TYPE_DISPLAY_PORT_MST or
SIGNAL_TYPE_DISPLAY_PORT then variable ret is uninitialized and this is
checked for > 0 at the end of the function. Ret should be initialized,
I believe setting it to zero is a correct default.

I met below warning when cating a small size(about 80bytes) txt file
on 9pfs(msize=2097152 is passed to 9p mount option), the reason is we
miss iov_iter_advance() if the read count is 0 for zerocopy case, so
we didn't truncate the pipe, then iov_iter_pipe() thinks the pipe is
full. Fix it by removing the exception for 0 to ensure to call
iov_iter_advance() even on empty read for zerocopy case.

This reverts commit 134f98bcf1b898fb9d6f2b91bc85dd2e5478b4b8.
The r8153_mac_clk_spd() is used for RTL8153A only, because the register
table of RTL8153B is different from RTL8153A. However, this function would
be called when RTL8153B calls r8153_first_init() and r8153_enter_oob().
That causes RTL8153B becomes unstable when suspending and resuming. The
worst case may let the device stop working.
Besides, revert this commit to disable MAC clock speed down for RTL8153A.
It would avoid the known issue when enabling U1. The data of the first
control transfer may be wrong when exiting U1.

Commit 5ee759cda51b ("l2tp: use standard API for warning log messages")
changed a number of warnings about invalid packets in the receive path
so that they are always shown, instead of only when a special L2TP debug
flag is set. Even with rate limiting these warnings can easily cause
significant log spam - potentially triggered by a malicious party
sending invalid packets on purpose.
In addition these warnings were noticed by projects like Tunneldigger [1],
which uses L2TP for its data path, but implements its own control
protocol (which is sufficiently different from L2TP data packets that it
would always be passed up to userspace even with future extensions of
L2TP).
Some of the warnings were already redundant, as l2tp_stats has a counter
for these packets. This commit adds one additional counter for invalid
packets that are passed up to userspace. Packets with unknown session are
not counted as invalid, as there is nothing wrong with the format of
these packets.
With the additional counter, all of these messages are either redundant
or benign, so we reduce them to pr_debug_ratelimited().

When we switch between SAGV on vs. off we need to reprogram all
plane wateramrks accordingly. Currently skl_wm_add_affected_planes()
totally ignores the SAGV watermark and just assumes we will use
the normal WM0.
Fix this by utilizing skl_plane_wm_level() which picks the
correct watermark based on use_sagv_wm. Thus we will force
an update on all the planes whose watermark registers need
to be reprogrammed.

Populate conn_state->max_bpc with something sensible from the start.
Otherwise it's possible that we get to compute_sink_pipe_bpp() with
max_bpc==0.
The specific scenario goes as follows:
1. Initial connector state allocated with max_bpc==0
2. Trigger a modeset on the crtc feeding the connector, without
actually adding the connector to the commit
3. drm_atomic_connector_check() is skipped because the
connector has not yet been added, hence conn_state->max_bpc
retains its current value
4. drm_atomic_helper_check_modeset() ->
drm_atomic_add_affected_connectors() -> the connector
is now part of the commit
5. compute_baseline_pipe_bpp() -> MISSING_CASE(max_bpc==0)
Note that pipe_bpp itself may not be populated on pre-g4x machines,
in which case we just fall back to max_bpc==8 and let .compute_config()
limit the resulting pipe_bpp further if necessary.

This adds a new SND_PCI_QUIRK(...) and applies it to the Intel NUC 10
devices. This fixes the issue of the devices not having audio input and
output on the headset jack because the kernel does not recognize when
something is plugged in.
The new quirk was inspired by the quirk for the Intel NUC 8 devices, but
it turned out that the NUC 10 uses another pin. This information was
acquired by black box testing likely pins.

Since commit 9e2369c06c8a18 ("xen: add helpers to allocate unpopulated
memory") foreign mappings are using guest physical addresses allocated
via ZONE_DEVICE functionality.
This will result in problems for the case of no balloon memory hotplug
being configured, as the p2m list will only cover the initial memory
size of the domain. Any ZONE_DEVICE allocated address will be outside
the p2m range and thus a mapping can't be established with that memory
address.
Fix that by extending the p2m size for that case. At the same time add
a check for a to be created mapping to be within the p2m limits in
order to detect errors early.
While changing a comment, remove some 32-bit leftovers.
This is XSA-369.

Bailing immediately from set_foreign_p2m_mapping() upon a p2m updating
error leaves the full batch in an ambiguous state as far as the caller
is concerned. Instead flags respective slots as bad, unmapping what
was mapped there right away.
HYPERVISOR_grant_table_op()'s return value and the individual unmap
slots' status fields get used only for a one-time - there's not much we
can do in case of a failure.
Note that there's no GNTST_enomem or alike, so GNTST_general_error gets
used.
The map ops' handle fields get overwritten just to be on the safe side.
This is part of XSA-367.
