Remove debug messages that served as sanity checks during the initial
implementation phase of underrun/overrun completion codes. These checks
are now unnecessary.
Instead, improve the default debug messages for underrun/overrun events,
so that they are consistent with the reset of the completion codes.

Move handling transfer events without a target transfer TRB into
handle_transferless_tx_event(), this type of event does not utilize the
rest of handle_tx_event() and as a result it's better to separate it
into a dedicated function.
Additionally, this change reduces handle_tx_event()'s size and makes it
more readable.

move the checks for all those cases into one xhci_link_chain_quirk()

xhci DbC driver polls the host controller for DbC events at a reduced
rate when DbC is enabled but there are no active data transfers.
Allow users to modify this reduced poll interval via dbc_poll_interval_ms
sysfs entry. Unit is milliseconds and accepted range is 0 to 5000.
Max interval of 5000 ms is selected as it matches the common 5 second
timeout used in usb stack.
Default value is 64 milliseconds.
A long interval is useful when users know there won't be any activity
on systems connected via DbC for long periods, and want to avoid
battery drainage due to unnecessary CPU usage.
Example being Android Debugger (ADB) usage over DbC on ChromeOS systems
running Android Runtime.

The transferred length is incorrectly zeroed for cancelled isoc
transfer TDs when the transfer ring stops on a cancelled TD with
a 'Stop - Length Invalid' completion code.
Length was always set to zero in these cases even if it should be
set to the sum of the TRB transfer block lengths up to
the TRB the ring stopped on, _excluding_ the one stopped on.
No issues reported due to this isoc case. Found while inspecting
related case in bulk transfer 'Stop - Length Invalid' handling.
Change this so that 'Stop - Length Invalid' transfer completion
cases always sum up TRB lengths instead of report a zero length.

Based on grepping through the source code this driver appears to be
missing a call to drm_atomic_helper_shutdown() at system shutdown
time. Among other things, this means that if a panel is in use that it
won't be cleanly powered off at system shutdown time.
The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart comes straight out of the kernel doc "driver
instance overview" in drm_drv.c.
This driver users the component model and shutdown happens in the base
driver. The "drvdata" for this driver will always be valid if
shutdown() is called and as of commit 2a07396828
("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a noop")
we don't need to confirm that "drm" is non-NULL.

DSB_STATUS bit 16 is supposed to be a sticky bit informing us whether
the DSB was idle or not when the pipe's delayed vblank (when double
buffered registers latch) occurred. Unfortunately it turns out this
is a level triggred signal, ie. the bit will be set whenever the
DSB is busy during the scanline window between start of delayed
vblank and vtotal. Try to document that fact by renaming the bit.
Sadly this also thwarts my plan to use this bit to sanity check
that the (to be introduced) DSB based vblank evasion did its job
correctly. That would require an edge triggered signal instead.
So looks like we'll have to rely mostly on luck instead :(

====================
Netfilter fixes for net
The following patchset contains two Netfilter fixes for net:
Patch #1 fixes CONFIG_SYSCTL=n for a patch coming in the previous PR
to move the sysctl toggle to enable SRv6 netfilter hooks from
nf_conntrack to the core, from Jianguo Wu.
Patch #2 fixes a possible pointer leak to userspace due to insufficient
validation of NFT_DATA_VALUE.
Linus found this pointer leak to userspace via zdi-disclosures@ and
forwarded the notice to Netfilter maintainers, he appears as reporter
because whoever found this issue never approached Netfilter
maintainers neither via security@ nor in private.

Add cmdq_pkt_logic_command to support math operation.
cmdq_pkt_logic_command can append logic command to the CMDQ packet,
ask GCE to execute a arithmetic calculate instruction,
such as add, subtract, multiply, AND, OR and NOT, etc.
Note that all arithmetic instructions are unsigned calculations.
If there are any overflows, GCE will sent the invalid IRQ to notify
CMDQ driver.
