The WARN_ON_ONCE/WARN_ON fired unconditionally on any completion
timeout, including the recoverable case where the interrupt was lost but
the hardware actually finished the transfer. This produced a noisy splat
with a full call trace even though the driver successfully recovered via
tegra_qspi_handle_timeout().
Since tegra210 uses threaded interrupts, the transfer completion can be
signaled before the interrupt fires, making this false positive case
common in practice.
Almost all the hosts I sysadmin in my fleet produce the following splat:
WARNING: CPU: 47 PID: 844 at drivers/spi/spi-tegra210-quad.c:1226 tegra_qspi_transfer_one_message+0x8a4/0xba8
....
tegra-qspi NVDA1513:00: QSPI interrupt timeout, but transfer complete
Move WARN_ON_ONCE/WARN_ON to fire only on real unrecoverable timeouts,
i.e., when tegra_qspi_handle_timeout() confirms the hardware did NOT
complete. This makes the warning actionable instead of just polluting
the metrics.

Prabhakar <prabhakar.csengg@gmail.com> says:
This patch series addresses three issues in the RZV2H RSPI driver:
1. The max_speed_hz field was advertising a prohibited bit rate, which
could lead to incorrect behavior when userspace applications attempt
to set the SPI clock speed.
2. The clock configuration logic allowed for an invalid combination of
SPR=0 and BRDV=0, which is not supported by the hardware.
3. Simplified the clock rate search function as min/max speed parameters
are not needed.
Note, patches apply on top of next-20260409.
The spr_min and spr_max parameters passed to
rzv2h_rspi_find_rate_variable() and rzv2h_rspi_find_rate_fixed() were
always called with RSPI_SPBR_SPR_MIN and RSPI_SPBR_SPR_MAX respectively.
There is no need to pass these as parameters since the valid SPR range
is fixed by the hardware.

The combination of SPR=0 and BRDV=0 results in the minimum division
ratio of 2, producing the maximum possible bit rate for a given clock
source. This combination is not supported in two cases:
- On RZ/G3E, RZ/G3L, RZ/V2H(P) and RZ/V2N, RSPI_n_TCLK is fixed at
200MHz, which would yield 100Mbps. The next hardware manual update
will explicitly state that since the maximum frequency of the
RSPICKn clock signal is 50MHz, settings with N=0 and n=0 resulting
in 100Mbps are prohibited.
- On RZ/T2H and RZ/N2H, when PCLK (125MHz) is used as the clock
source, SPR=0 and BRDV=0 is explicitly listed as unsupported in
the hardware manual (Table 36.7).
Skip the SPR=0/BRDV=0 combination in rzv2h_rspi_find_rate_fixed() to
prevent the driver from selecting an invalid clock configuration on the
affected SoCs.
Additionally, remove the now redundant RSPI_SPBR_SPR_PCLK_MIN define
which was previously set to 1 to work around the PCLK restriction, but
was overly broad as it incorrectly blocked valid combinations such as
SPR=0/BRDV=1 (31.25Mbps on PCLK=125MHz).

On RZ/V2H(P), RZ/G3E and RZ/G3L, RSPI_n_TCLK is fixed at 200MHz.
The max_speed_hz was computed using clk_round_rate(tclk, ULONG_MAX)
with SPR=0 and BRDV=0, resulting in 100Mbps - the exact combination
prohibited on these SoCs. This could cause the SPI framework to request
a speed that rzv2h_rspi_find_rate_fixed() would skip, potentially
leading to a clock selection failure.
On RZ/T2H and RZ/N2H the max_speed_hz was correctly calculated as
50Mbps for both the variable PCLKSPIn and fixed PCLK clock sources.
Since the maximum supported bit rate is 50Mbps across all supported SoC
variants, replace the clk_round_rate() based calculation with a define
RSPI_MAX_SPEED_HZ set to 50MHz and use it directly for max_speed_hz.

This codec driver depended on the legacy GPIO API, and nothing
in the kernel is defining the platform data, so get rid of this.
Two in-kernel device trees are defining this codec using
undocumented device tree properties, so support these for now.
The same properties can be defined using software nodes if board
files are desired. The device tree use the "-gpio" rather than
"-gpios" suffix but the GPIO DT parser will deal with that.
Since there may be out of tree users, migrate to GPIO descriptors,
drop the platform data that is unused, and assign the dac_clk the
value that was used in all platforms found in a historical dig,
and support setting the clock to the PLL using the undocumented
device tree property.
Add some menuconfig so the codec can be selected and tested.

We currently create a single DPT for the entire FB, so we can't
actually do the per-plane remap. Reject it for now.

`ip6t_eui64`, `xt_mac`, the `bitmap:ip,mac`, `hash:ip,mac`, and
`hash:mac` ipset types, and `nf_log_syslog` access `eth_hdr(skb)`
after either assuming that the skb is associated with an Ethernet
device or checking only that the `ETH_HLEN` bytes at
`skb_mac_header(skb)` lie between `skb->head` and `skb->data`.
Make these paths first verify that the skb is associated with an
Ethernet device, that the MAC header was set, and that it spans at
least a full Ethernet header before accessing `eth_hdr(skb)`.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
Use the TRAILING_OVERLAP() helper to fix the following warnings:
1 net/netfilter/x_tables.c:816:39: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
1 net/netfilter/x_tables.c:811:39: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
This helper creates a union between a flexible-array member (FAM)
and a set of members that would otherwise follow it. This overlays
the trailing members onto the FAM while preserving the original
memory layout.

UDP-Lite (RFC 3828) socket support was recently retired from the core
networking stack. As a follow-up of that, drop the connection tracker
and NAT support for UDP-Lite in Netfilter.
This patch removes CONFIG_NF_CT_PROTO_UDPLITE and scrubs UDP-Lite
awareness from the conntrack core, NAT core, nft_ct, and ctnetlink.
Please note that stateless packet inspection, matching, ipsets or
logging support for IPPROTO_UDPLITE is preserved.
As conntrack no longer extracts UDP-Lite ports or tracks its L4 state,
when performing NAT the UDP-Lite checksum cannot be updated anymore.
That is an expected and acceptable consequence of removing UDP-Lite
conntrack module.

Originally this did not matter because defrag was enabled once per netns
and only disabled again on netns dismantle. When this got changed I should
have adjusted checkentry to not leave defrag enabled on error.

Add pr_fmt to prefix log messages with the module name for
easier debugging in dmesg.
Add checkentry functions for IPv4 (ttl_mt_check) and IPv6
(hl_mt6_check) to validate the match mode at rule registration
time, rejecting invalid modes with -EINVAL.
The evaluation function returns false in case the mode is
unknown, so this is a cleanup, not a bug fix.

Add /proc/net/ip_vs_status to show current state of IPVS.
The motivation for this new /proc interface is to provide the output
for the users to help them decide when to tune the load factor for
hash tables, which is possible with the new sysctl knobs coming in
followup patch.
The output also includes information for the kthreads used for stats.
